We have released a new clip to the series of Bird Migration Videos in our Youtube channel. We filmed it exactly one year ago. On this third episode we present the onset of the White Stork migration. We also talk about other migrants in the Strait of Gibraltar this time of the year, like black kites and swifts.

Bird migration videos for all

The large concentration of White Storks and Black Kites in the Tarifa area offers a magnificent spectacle. This show does not only draw the attention of keen birders, but regular tourists visiting Cadiz in summer are also stunned by it. Indeed, July and August is an excellent period for family birding in the Strait of Gibraltar.

The big show of the smaller birds

The migration of smaller birds is equally astonishing for the trained eye. It is currently known that the Strait of Gibraltar funnels the migration of European birds to Africa in a much bigger proportion than traditionally assumed. For instance, thousands of Common and Pallid Swifts can be seen heading south in a few hours. In addition, continuous flocks of migrant European bee-eaters can be heard by night as well.

The big days of “autumn” migration have only started. One more year, Birding The Strait will be offering birding wildlife excursions during this exciting time.

El Cernícalo Primilla en Tarifa

Las antiguas murallas del castillo de Guzmán el Bueno en Tarifa (Cádiz), albergan la colonia más meridional de cernícalo primilla de todo el continente europeo. Este es uno de los pocos sitios donde esta especie, típicamente migratoria, pasa el invierno en Europa. Desafortunadamente, la población del cernícalo primilla está sufriendo una disminución dramática en todo su ámbito de distribución. Esto se debe a múltiples factores. Es clave para la conservación de este fascinante y pequeño halcón, concienciar a las personas sobre su presencia y su interesante estilo de vida dentro de los núcleos urbanos. Por este motivo decidimos organizar un paseo guiado para conocer el Cernícalo Primilla en Tarifa, dentro del evento MigBird, promocionado por el Ayuntamiento de Tarifa.

El próximo sábado día 20, Birding The Strait ofrecerá una excursión gratuita por el Castillo. La colonia de cría del cernícalo primilla será el tema central de la actividad. Sin embargo, seguro que tendremos la oportunidad de observar muchas otras especies de aves también.

Esta actividad es parte de la responsabilidad social corporativa de Birding The Strait¡Ven y participa con nosotros!

Queremos agradecer a los 17 participantes por su amabilidad y entusiasmo. La mañana voló observando cernícalos primilla alrededor de sus nidos. Además, hemos visto numerosos milanos negros en migración activa desde África. Ha sido muy gratificante hablar con este variado grupo de entusiastas de la naturaleza de Tarifa, la provincia de Cádiz, otras regiones de España, Holanda y Suiza.

La sorpresa más gratificante para nosotros ha sido descubrir el notable conocimiento de las aves y la naturaleza de los participantes más jóvenes. Sin duda, iniciativas locales como MigBird están contribuyendo significativamente a aumentar la conciencia para la conservación de la vida silvestre en Tarifa. ¡Esto es realmente alentador! En Birding The Strait seguiremos trabajando en esta dirección tanto como podamos.

Finalmente, queremos agradecer a Diego y Lucía, del Ayuntamiento de Tarifa, por su apoyo.

Lesser Kestrels in Tarifa

The ancient ramparts of Guzman el Bueno Castle in Tarifa, hold the southernmost colony of Lesser Kestrels in the continent. In addition, this is one of the few sites where this typically migrant species overwinters in Europe. Unfortunatelly, the Lesser Kestrel population has suffered a dramatic decline throughout its range. This is due to multiple factors. This way, make people aware about the presence and fascinating lifestyle of this charming raptor is a key factor towards its conservation.

Tarifa #MigBird

Next Saturday 20th, Birding The Strait will be offering a free excursion around the Castle. The breeding colony of Lesser Kestrel will be the central subject of the activity. However, we will certainly have the chance to observe many other species as well.

This activity is part of Birding The Strait corporate responsibility . Come join us!

Aftermath

We want to thank the 17 participants for their friendliness and enthusiasm. The morning just flew by observing Lesser Kestrels around their nests. Moreover, we have seen numerous Black Kites in active migration from Africa. It has been very rewarding to discuss with this varied group of nature enthusiasts from Tarifa, other regions of Spain, Holland and Switzerland.

The most rewarding surprise has been to realize the remarkable knowledge for birds and nature by the youngest participants. No doubt, local initiatives such as MigBird are significantly contributing to increase the awareness for wildlife conservation in Tarifa. This is really encouraging! In Birding The Strait we will keep working in this direction as much as we can.

Finally, we want to thank Diego and Lucia, from the Tarifa Town Hall, for their support.

If you are interested in visiting this colony and learn more about the Lesser Kestrel and the other resident and migratory raptors, contact us!

Yes friends, the time has come!

One more year, since time immemorial, the raptor migration has started in Tarifa and the Strait of Gibraltar.

Black Kites on the move

Black Kites are always the first to be noticed. They are on the move in growing numbers. Adults are now in a race from their African wintering quarters to their breeding grounds in Europe. They are in a hurry to occupy the best possible nest site. The Sahara, the ocean, weather constrains and human infrastructure will be the main threats they will have to face. The Black Kite is, by far, the most abundant of all the raptors using this flyway. They often kettle in enormous flocks and gather in communal roosts providing a world class spectacle.

Bird Migration Series Part I & II

To celebrate this, we release in our youtube channel the second video of the Birding The Strait migration series. Follow this link to see the Part I.

The new video shows the spring migration back from Africa of the Black Kite  in the Strait of Gibraltar. It contains a selection of the best footage we have filmed over the last springs in Tarifa, the Strait of Gibraltar and Los Alcornocales Natural Park.


The show has only started. Birding The Strait will be offering guided birding day trips and tailor-made tours in Tarifa and the Strait of Gibraltar throughout the season. Feel free to contact us anytime for further information!

Birding Trip to the Western Sahara

Little Owls of the Saharae subspecies show a striking phenotypic adaptation to desert environment. This is one of the palest individuals we have recorded in the Western Sahara, where they are very variable.

We have just returned from a thrilling wildlife expedition into one of the most remote regions of the Western Palearctic: the Western Sahara. More precisely, we have spent 8 days exploring the wildlife and landscapes within the Dakhla, Aousserd and Bir Anzarane triangle. This has led us to ridges of dunes, extensive mudflats, forested wadis, endless steppes, rock massifs, unexpected waterholes and even off into the Atlantic Ocean. On this post we summarize some impressions and highlights of this Birding Trip to the Western Sahara.

Our second Birding Trip to the Western Sahara

Bay of Dakhla. The vast intertidal mudflats surrounded by sand dunes and arid planes create a very characteristic and powerful landscape.

Back in February 2016 we were invited by the Dakhla Attitude Hotel to a fam trip in the region. This was a memorable experience and we have been eagerly looking forward to returning since then. On this link you can read the trip report of our previous trip to the Western Sahara, including a large selection of pictures.

During our 2019 expedition we wanted to relocate key sites and target species, explore new trails getting deeper into the desert, reinforce our collaboration with local experts and logistics, and conduct nocturnal surveys for mammals. On this last (but not least) matter, our primary target was to observe the Sand Cat Felis margarita. This is probably the most elusive and least known feline in the Palearctic.

From our camp near Aousserd we could observe a pair of Golden Eagles around their nest, an African Golden Wolf peacefully standing by its lair in day time, a group of Pale Rock Martins, a Lanner and, above all, the immensity of the unexploited Saharan steppe.

In doing so we have camped in the desert and slept in jaimas (nomad tents) belonging to Saharawi camel herders, but also in cozy hotels in Dakhla. As for the transportation, we have used hired passengers cars and 4×4 with local expert drivers to safely get off the beaten track into the desert. Moreover, we used a boat to reach the most inaccessible corners of the huge Bay of Dakhla.

Using eBird in the Western Sahara

As usual during our Birding The Strait trips, we have invested a considerable effort to systematically upload all the resulting ornithological information to eBird, including pictures and sound recordings. This is our humble contribution to citizen science. As keen eBirders we have found it very exciting to complete bird checklists in some regions which have barely, if at all, being surveyed before. This way, all our records are accessible for the public in our eBird accounts, which can be consulted here (Yeray) and here (Javi).

We took much effort to report on eBird most of the birds we saw and heard during our trip. We also uploaded several pictures, like this of a Greater Hoopoe Lark. Picture by Yeray Seminario.

The Desert environment and its changing conditions

Birding in semi-desert environments always implies a high degree of uncertainty and surprise. Here, rainfall in precedent months and the resulting plant coverage is the main driving force. This way, some of the best and richer birding sites we found in 2016, such as the eastern end of the Aousserd road and Oued Jenna were very dry and quiet this time. In turn, the regions nearer the coast held a greener plant coverage and several flooded and very productive waterholes!

We got to see several flocks of dozens of Spotted Sandgrouse, along with fewer numbers of Crowned Sandgrouse. Picture by Yeray Seminario.
We got to see several flocks of dozens of Spotted Sandgrouse, along with fewer numbers of Crowned Sandgrouse.

Accordingly, some species which we struggled to find in 2016 were amongst the most widespread this year. This was the case of the Temminck’s Lark, for instance. In turn, the Black-crowned Sparrow-Lark was more scarce, although still well represented. Besides, the local specialties, like Saharan Dunn’s Lark and Cricket Longtail seemed to be in similar numbers. During this trip we missed some important targets including Sudan Golden Sparrow and Golden Nightjar. However, we enjoyed unbeatable observations of Pale Rock Martin, African Royal Tern, Spotted and Crowned Sandgrouses, and Houbara Bustard, to name but a few!

The Thick-billed Lark is one of the most impressive Larks in the region. This individual was photographed close to Aousserd in our 2016 expedition.

In this trip we have recorded a total of 86 bird scpecies, and a grand total of 111  considering our two visit to the Dakhla-Aousserd region.

Birding Highlights

Aside from the birds mentioned, other birding highlights during our trip included:

  1. A gang of Fulvous Chatterers breaking into our campsite in Oued Jenna to feed on our supplies and drink our water!Fulvous Chatterer by Yeray Seminario
  2. A flock of 5 Pale Rock Martins flying and contact-calling overhead.Pale Rock Martin by Yeray Seminario
  3. A male Houbara Bustard literally in the middle of nowhere.
  4. Two Pharaoh Eagle-Owls illuminated by our torches
  5. A pair of Lanner Falcons landing by a waterhole as we were watching Spotted and Corwned Sangrouses drinking.Lanner Falcons and flock of Spotted Sandgrouse by Yeray Seminario
  6. Several family groups of Cream-coloured Courses.
  7. Up to 8 different Cricket Longtails  at Oued Jenna.
  8. Large groups of Sandwich, Caspian, Common and African Royal Tern observed while navigating in the Bay of Dakhla with impressive sand dunes in the background.Mixed flocks of terns by Javi Elorriaga
  9. We enjoyed observing and photographing the varied array of Larks and Wheatears in their different plumages and variations, namely: Desert, Black, Black-earedNorthern, White-crowned and Red-rumped Wheatear; and Short-toed, Desert, Bar-tailed, Dunn’s, Black Crowned, Thick-billed, Temminck’s, Greater Hoopoe and Maghreb (Crested) Lark

The observation of two putative Maghreb Larks North of Bir Anzarane deserves special mention. Indeed, the taxonomic rank of the so-called “long-billed” Crested Larks is nowadays unclear. Interestingly, the presence of birds belonging to the senegalensis group of the Crested Lark in the region has been proposed. On this eBird checklist we have uploaded photos of two different “long-billed” larks, including a sound recording. We have provissionally asigned the records to Maghreb Lark Galerida macrorhyncha, but see also Qninba et al. 2019.  Are we facing yet another case of a typically Sahelian taxa expanding North into the Western Palearctic? Comments welcome!

Interestingly, we found two Corn Buntings around a waterhole not far from Dakhla. Much to our surprise, we later got to know that this was among the very first reports for the species in the region!

Mammal Watching

Mammals deserve special mention here. To our pleasure, we managed to find the sought-after Sand Cat! Indeed, we got to find this precious desert creature in each of our night surveys. Amazingly one of the encounters involved a Sand Cat hidden in low bushes a couple of meters from us! Never in our wildest dreams did we expect such an amazing observation.

Sand Cat in the Western Sahara. Photo by Javi Elorriaga/Birding The Strait
Sand Cat in the Western Sahara. This up close and personal encounter was one of the highlights of the trip.

But that was not it! An African Golden Wolf peacefully standing by its lair in the middle of the day made another highly unlikely target accomplished. In following nights, we had two additional encounters with wolfs while using torches from the car (stay tuned for the forthcoming nocturnal footage).

The list of mammas was completed with one Fennec, two Rüppel’s Foxes, African Savanna Hare, gerbils and the skull of a Saharan Striped Polecat.

We will return!

We are fascinated by the wildlife, landscape and tranquillity of this region. As expected in such an arid region, the density and diversity of birds is comparatively low. However, the interest and uniqueness of the avian community at the Western Palearctic level is out of question. The sense of wilderness greatly enhances the experience and the possibility of “coming through something new and unexpected” brings birding to a higher level. Moreover, the high chances of connecting with mammal species hard to find in other regions of the Maghreb is, no doubt, an additional highlight.

The Dunn's Lark is another local speciality Indeed, the Aousserd region is probably the most reliable site to observe this little known species within the Western Palearctic. Photo by Javi Elorriaga/Birding The Strait

Viaje de observación de aves y naturaleza en el Sáhara Occidental

Los mochuelos de la subespecie “Saharae” muestran una sorprendente adaptación fenotípica al ambiente desértico. Este es uno de los individuos más pálidos que hemos registrado en el Sáhara Occidental, donde son muy variables.

Acabamos de regresar de una emocionante expedición de naturaleza y vida salvaje a una de las regiones más remotas del Paleártico Occidental: el Sáhara Occidental. Más precisamente, hemos pasado 8 días explorando paisajes y naturaleza dentro del triángulo Dakhla, Aousserd y Bir Anzarane. Esto nos ha llevado a crestas de dunas, extensas marismas, wadis boscosos, estepas interminables, macizos rocosos y pozos de agua inesperados. En este artículo resumimos algunas de las impresiones y aspectos destacados de este viaje de observación de aves y naturaleza en el Sahara Occidental.

Nuestro segundo viaje de observación de aves al Sahara Occidental

Bahía de Dakhla. Las vastas marismas intermareales rodeadas de dunas de arena y mesetas áridas crean un espectacular paisaje muy característico.

En febrero de 2016, fuimos invitados por el Hotel Dakhla Attitude a un viaje de reconocimiento de la región. Para nosotros fue una experiencia memorable y desde entonces hemos estado ansiosos por volver. En este enlace puedes leer el diario completo de nuestro viaje anterior al Sáhara Occidental. En él, se incluye una buena selección de imágenes.

Durante nuestra expedición de 2019, queríamos reubicar sitios clave y especies objetivo. También explorar nuevos senderos que se adentren en el desierto, reforzar nuestra colaboración con expertos locales y de logística y realizar salidas nocturnas para mamíferos. En este último, pero no menos importante, asunto, nuestro objetivo principal era observar el gato de las arenas o gato del desierto Felis margarita. Este es probablemente el felino más esquivo y menos conocido en el Paleártico.

Great scenery by our camp in Leglat. Western Sahara.
Desde nuestro campamento cerca de Aousserd pudimos observar una pareja de águila real alrededor de su nido, un lobo dorado africano descansando pacíficamente junto a su guarida en pleno día, un grupo de aviones isabelinos, un halcón borní y, sobre todo, la inmensidad de la estepa  sahariana sin explorar aún.

Acampamos en el desierto y dormimos en jaimas (tiendas nómadas), pertenecientes a pastores de camellos saharauis, pero también en acogedores hoteles en Dakhla. En cuanto al transporte, utilizamos automóviles contratados y vehículos 4×4 con conductores expertos locales. De esta manera, pudimos salir a los caminos más complicados de forma segura. Además, utilizamos un barco para llegar a los rincones más inaccesibles de la enorme Bahía de Dakhla.

Usando eBird en el Sáhara Occidental

Como de costumbre, durante nuestros viajes en Birding The Strait, hemos invertido un esfuerzo considerable para cargar sistemáticamente toda la información ornitológica resultante en eBird. Esto incluye las imágenes y grabaciones de audio. Esta es nuestra humilde contribución a la ciencia ciudadana. Como entusiastas eBirders, hemos descubierto que es muy emocionante crear listas de aves en regiones que apenas han sido prospectadas antes. Si es que lo han sido alguna vez… De esta manera, todos nuestros registros son accesibles para el público en nuestras cuentas de eBird. Se pueden consultar aquí: cuenta de Yeray y cuenta de Javi.

Nos esforzamos mucho para registrar en eBird todas las aves que vimos y escuchamos durante nuestro viaje. También hemos subido varias fotos, como esta de una alondra ibis, muy extendida en la región.

El desierto y sus condiciones cambiantes

La observación de aves en ambientes semidesérticos implica un alto grado de incertidumbre y sorpresa. Aquí, la lluvia en los meses precedentes y la cobertura vegetal resultante es la principal fuerza impulsora de la vida. De esta manera, algunos de los mejores sitios de observación de aves que encontramos en 2016, como el extremo este de la carretera Aousserd y Oued Jenna, este año estaban muy secos y tranquilos. Sin embargo, las regiones más cercanas a la costa tenían una cobertura vegetal más verde y varios pozos de agua inundados muy productivos.

Pudimos ver varios bandos de docenas de gangas moteadas y un menor número de gangas coronadas.

Por otro lado, algunas especies difíciles de encontrar en 2016 fueron muy frecuentes este año. Este fue el caso de la alondra sahariana, por ejemplo. Sin embargo, la terrera negrita fue más escasa, aunque todavía bien representada. Además, las especialidades locales, como la alondra de Dunn y la prinia charlatana aparecieron en números similares. Durante este viaje, no vimos algunas especies importantes, como el gorrión dorado o el chotacabras dorado. Sin embargo, disfrutamos de observaciones inmejorables de avión isabelino, charrán real (subespecie albididorsalis), gangas moteadas y coronadas y avutardas hubaras ¡por nombrar algunos!

La calandria picogorda es una de los alaudidos más impresionantes de la región. Este individuo fue fotografiado cerca de Aousserd en nuestra expedición de 2016.

A lo largo de este viaje hemos registrado un total de 86 especies de aves. Esto hace un total de 111 especies, considerando nuestras dos visitas a la región de Dakhla-Aousserd.

Lo más destacado de las aves y naturaleza en el Sahara

Además de las aves mencionadas anteriormente, otras especies destacadas durante nuestro viaje incluyen:

  1. ¡El grupo de turdoides rojizos irrumpiendo en nuestro campamento en Oued Jenna para alimentarse de nuestros suministros y beber de nuestra agua nos sorprendió!
  2. Bandos de aviones isabelinos volando y reclamando justo encima de nosotros.
  3. Un macho de avutarda hubara africana literalmente en medio de la nada.
  4. Dos búhos desérticos iluminados por nuestras linternas.
  5. Un par de halcones borní en el bebedero donde estábamos viendo beber a las gangas moteadas y coronadas.
  6. Varios grupos familiares de corredores saharianos.
  7. Hasta 8 prinias charlatanas diferentes en Oued Jenna.
  8. Grandes grupos de charranes patinegros, pagazas piquirrojas y charranes común y real. Los pudimos observar desde el barco en la bahía de Dakhla, con las impresionantes dunas como fondo. 
  9. Disfrutamos observando y fotografiando la variada diversidad de collalbas y alondras en sus diferentes plumajes y variaciones. Entre ellas vimos: collalba desértica rubia, gris, negra de Brehm, y la culirroja; terreras común, sahariana, colinegra y negrita; alondras de Dunn, de pico grueso, sahariana e ibis y la cogujada magrebí.

Observación de Cogujada Magrebí

La observación de dos supuestas cogujadas magrebíes al norte de Bir Anzarane merece una mención especial. De hecho, el rango taxonómico de las llamadas cogujadas de “pico largo” no está claro en la actualidad. Curiosamente, se ha propuesto la presencia de aves pertenecientes al grupo senegalensis de la cogujada en la región. En esta lista de eBird hemos subido fotos de dos cogujadas diferentes de “pico largo”, incluyendo una grabación de sonido. Hemos asignado los registros a cogujada magrebí Galerida macrorhyncha, pero es interesante leer el artículo de Qninba et al. 2019. ¿Nos enfrentamos a otro caso de taxones típicamente del Sahel que se expanden hacia el norte en el Paleártico occidental? ¡Los comentarios bienvenidos!

Curiosamente, encontramos dos trigueros cerca de un bebedero no lejos de Dakhla. Para nuestra sorpresa, ¡más tarde supimos que este fue uno de los primeros registros de esta especie en la región!

Observación de mamíferos

En este viaje, los mamíferos merecen una mención especial. ¡Para nuestro gozo, logramos encontrar el codiciado gato del desierto, también llamado de las arenas! De hecho, conseguimos encontrar a esta preciosa criatura del desierto en cada una de nuestras salidas nocturnas. ¡Sorprendentemente, en uno de los avistamientos, el gato del desierto estaba escondido en unos arbustos bajos a tan solo un par de metros de nosotros! Jamás habríamos soñado una observación tan asombrosa.

Sand Cat. Photography by Javi Elorriaga, Birding The Strait.
Gato de las arenas en el Sáhara Occidental. Este encuentro cercano y personal fue uno de los aspectos más destacados del viaje.

¡Pero esto no fue todo! Un lobo dorado africano descansaba tranquilamente en su guarida al medio del día. De repente, habíamos logrado otro objetivo altamente improbable. En las noches siguientes, usando linternas desde el coche, tuvimos dos encuentros adicionales con lobos (estad atentos a las próximos vídeos nocturnos que tenemos en preparación).

Lobo Africano observado muy cerca de Aousserd

La lista de mamíferos se completa con un fénec, dos zorros de Rüppel, una liebre africana de sabana, jerbos y el cráneo de una zorrilla líbica.

¡Volveremos!

Hemos acabado realmente fascinados por la naturaleza salvaje, los paisajes y la tranquilidad de esta región. Como se esperaba en una región tan árida, la densidad y diversidad de aves es relativamente baja. Sin embargo, el interés y la singularidad de la comunidad aviar a nivel de Paleártico Occidental están fuera de discusión. La sensación de naturaleza salvaje mejora enormemente la experiencia. La posibilidad de “descubrir algo nuevo e inesperado” lleva a la observación de aves a un nivel superior. Además, las altas posibilidades de hallar especies de mamíferos difíciles de encontrar en otras regiones del Magreb es, sin duda, un punto extra adicional.

Gracias a la experiencia con la vida salvaje y la logística recopilada en nuestras dos expediciones a la región, ya estamos trabajando para ofrecer un nuevo viaje dedicado especialmente al Sahara Occidental.

Por último, queremos agradecer a Patrick Bergier y Go-South por la valiosa información que nos han proporcionado.

Bird Migration Videos in the Strait of Gibraltar – Part I

Short-toed Eagle crossing the Strait of Gibraltar, by Javi Elorriaga
Short-toed Eagle crossing the Strait of Gibraltar

Today we release in our Youtube channel the first of a series of bird migration videos in the Strait of Gibraltar. We have filmed these videos over the last three years around Tarifa. This is part of a collaboration project with the Nature Agency at the Ministry of Environment of Denmark . These videos make part of the exhibition on bird migration at the Skagen Grey Lighthouse information center (Denmark).

The Strait: a major migration bottleneck

The Strait of Gibraltar is the most important bottleneck in the flyway of the Short-toed Eagle between Europe and Africa. This video shows striking images of eagles in active migration across the Strait. The footage stresses the vital challenge that sea-crossing represents for soaring migrants (enable subtitles).

During 2019 we will upload new videos of this series to our Youtube channel, Stay tuned!

The Empire of the Eagle and Águila de Bonelli: Book review

Review of Empire of the Eagle and Águila de Bonelli
Review of Empire of the Eagle and Águila de Bonelli

There’s no denying, at Birding The Strait we are passionate about Eagles. We love seeking for them, photographing them and simply observing them in the wild. We are also wildlife photography and bird books enthusiasts. Indeed, this is one of our main sources of expenditure! So, we were excited to see two new books coming out last month: ‘The Empire of the Eagle’ by Mike Unwin and David Tippling, and ‘Águila de Bonelli (Bonelli’s Eagle)’ by Tony Peral.

Both have a special meaning for us. We contributed with a few pictures for the book ‘The Empire of the Eagle’ and we were looking forward to seeing them on print. On the other hand, ‘Águila de Bonelli’ has been created, edited and published by a friend of us, the photographer and naturalist, Tony Peral.

Review of ‘Águila de Bonelli’

Packaging of 'Águila de Bonelli' by Tony Peral

You know you are in front of a special book the moment the package with ‘Águila de Bonelli’ is being delivered. The amazing packaging with a Bonelli’s Eagle printed on the box and the wax seal, is really unique and classy. Some would compare the experience to the one you get when purchasing a limited edition vinyl. From the moment you untie the strings and open the box, you are on a trip to the land of the Bonelli’s Eagles.

Cover of 'Águila de Bonelli' by Tony Peral
Cover of ‘Águila de Bonelli’ by Tony Peral

The cover shows an adult female in flight. She is missing one of her tail feathers, which does nothing but improve the visual impact of the photography. It’s truly a statement of intents. The author, Tony Peral, provides further insight on the magnitude of his work stating in the introduction that he stopped counting the hours spent in his hide after 3000!

Good and authoritative texts

The book begins with six concise and well written chapters by Jose María Gil Sánchez and consists on an updated review of the biology and conservation of the species. English-speakers, don’t get distracted by the title, this book has been translated into English. However, the photographies, which are the most important part of the book are universal.

From there, as the prestigious Markus Varesvuo says in the prologue, comes a true festival of almost 100 photos, all of them of superb quality. The first, a double-page image, shows a subadult Bonelli’s Eagle right in the moment she is catching a Red-legged Partridge. Next page, an adult folds its wings to dive directing its gaze on you!

Every single photo on 'Águila de Bonelli' is fantastic

Not a single photo in the book is a filler, none is redundant, and none seems to be done in a known set or hide. Moreover, some photos in this book show scenes of Bonelli’s eagles very rarely seen before. This is one of those books that, if a child happens to find, it is very likely that he will want to be a wildlife photographer.

Review of ‘The Empire of the Eagle’

‘Empire of the Eagle’ is a compilation of texts and photographs of all the species of eagles in the worldby Mike Unwin, with selected photographies, curated by a renowned photographer: David Tipling .

This is a hardcover book with a clear emphasis on the photography side. Indeed, the introduction describes the book as “a photographic celebration of all the world’s eagles”. Sixty-eight species are treated throughout its 288 pages and distributed in five main sections: ‘Hunters of the Uplands’, ‘Predators of the Plains’, ‘Assasins of the Woodlands’, ‘Raptors of the Rainforest’ and ‘Wings over the Water’. Hence, unlike most of the books that treat groups of different species, the eagles are ordered by habitat, and not in taxonomic or alphabetic order.

Great summaries of  each raptor species

First, we find a brief Introduction section that deals with the personal attachment of the author to eagles. The authors also talk about the relevance of eagles in culture and history, its biology and conservation challenges.

The texts contain information about the natural history of each species, following a similar structure in all the cases. They include references to scientific research and anecdotic information, all written on an easy-reading, colloquial way. In any case, they are well documented, and deal with some very specific information. They occasionally include recent research results, adding to the overall value of the book. We can safely define the texts as brief summary introductions on each species.

An excellent compilation of eagle images

The quality of most images on the book is excellent. Also, the printing quality is what you would expect on a high-profile photography book. We noticed how some of the rarest species lack a spectacular image to depict the bird. There are probably not many photographies of some of these rare species out there! These pictures are an important testimony to how little we know about some eagle species in the world.

Which one we recommend?

We eagerly recommend both “Empire of the Eagle” and “Águila de Bonelli”. They are great books for anyone keen on wildlife. Specially, for those who are passionate about one of the most majestic groups of animals: the birds of prey. With christmas just around the corner, these remarkable books are a perfect gift!

“The Empire of the Eagle” y “Águila de Bonelli”: reseñas de libros

Review of Empire of the Eagle and Águila de Bonelli
Reseñas de “The Empire of the Eagle” (El imperio del águila) y “Águila de Bonelli”

No se puede negar, en Birding The Strait nos apasionan las águilas. Nos encanta buscarlas, fotografiarlas o simplemente observarlas en la naturaleza. También somos unos entusiastas de la fotografía de naturaleza y de los libros de aves. De hecho, estos son unos de nuestros principales desembolsos. Así que estábamos emocionados de ver dos nuevos libros que han salido el mes pasado: “The Empire of the Eagle” de Mike Unwin y David Tippling, y “Águila de Bonelli” de Tony Peral.

Ambos tienen un significado especial para nosotros. Contribuimos con algunas imágenes para el libro “The Empire of the Eagle” y estábamos ansiosos por verlas impresas. Por otro lado, “Águila de Bonelli”, un libro sobre el Águila Perdicera, ha sido creado, editado y publicado por un amigo nuestro, el fotógrafo y naturalista Tony Peral.

Ya sabes que estás frente a un libro especial en el momento en que recoges el paquete de “Águila de Bonelli”. El sorprendente empaquetado con un águila de Bonelli impresa en la caja y el sello de cera es realmente único y elegante. Algunos compararían la sensación con la que obtienes al comprar un vinilo de edición limitada. Desde el momento en que desatas los hilos y abres la caja, te sumerges en un viaje a la tierra de las águilas de Bonelli.

La portada muestra a una hembra adulta en vuelo. Le falta una de sus plumas de cola, cosa que no hace más que mejorar el impacto visual de la fotografía. Es realmente una declaración de intenciones. El autor, Tony Peral, proporciona más información sobre la magnitud de su trabajo ¡al afirmar en la introducción que dejó de contar las horas que pasó en su escondite fotográfico después de las 3000!

Textos acreditados de gran calidad

El libro comienza con seis capítulos concisos y bien escritos de José María Gil Sánchez y consiste en una revisión actualizada de la biología y la conservación de la especie. Hablantes de inglés, no se distraigan con el título, este libro también ha sido traducido al inglés. Aún así, las fotografías, que son la parte más importante del libro, son universales.

Un festival de fotografías de águila perdicera

Cada fotografía contenida en el libro “Águila de Bonelli” es fantástica.

A partir de aquí, como dice el prestigioso Markus Varesvuo en el prólogo, llega un verdadero festival de casi 100 fotos, todas ellas de excelente calidad. La primera, una imagen a doble página, muestra un águila perdicera subadulta justo en el momento en que atrapa una perdiz roja. En la página siguiente, un adulto pliega sus alas para dirigir su mirada hacia el lector.

Ni una sola foto en el libro es un relleno, ninguna es redundante y ninguna parece hacerse en un  sitio o posadero conocido. Además, algunas fotos en este libro muestran escenas de las águilas perdiceras muy raramente vistas antes. Este es uno de esos libros que, si un niño lo encontrase, es muy probable que quisiera ser fotógrafo de naturaleza.

Este libro en inglés: ‘Empire of the Eagle’ está escrito por Mike Unwin, que realiza una recopilación de textos sobre todas las especies de águilas en el mundo. Las fotografías están seleccionadas por un reconocido fotógrafo: David Tipling.

Este es un libro de tapa dura con claro énfasis fotográfico. De hecho, la introducción describe el libro como “una celebración fotográfica de todas las águilas del mundo”. En sus 288 páginas, el libro trata sesenta y ocho especies, distribuidas en cinco secciones principales: ‘Cazadores de las tierras altas’, ‘Depredadores de las llanuras’, ‘Asesinos de los bosques’, ‘Rapaces de la selva’ y ‘Alas sobre el agua’. Por lo tanto, a diferencia de la mayoría de los libros que tratan grupos de diferentes especies, las águilas están ordenadas por hábitat y no en orden taxonómico o alfabético.

Buenos textos recopilatorios sobre todas las águilas

Primero, encontramos una breve introducción que trata sobre el apego personal del autor a las águilas. Los autores también hablan sobre la relevancia de las águilas en la cultura y la historia, sus desafíos biológicos y de conservación.

Los textos contienen información sobre la historia natural de cada especie, siguiendo una estructura similar en todos los casos. Incluyen referencias a investigaciones científicas e información anecdótica, todas escritas de manera coloquial y de fácil lectura. En cualquier caso, están bien documentados y tratan con información muy específica. Ocasionalmente, incluyen resultados de investigaciones recientes, que se suman al valor general del libro. Podemos asegurar que los textos son como pequeñas introducciones resumidas de cada especie.

Una excelente selección de imágenes de águilas

La mayoría de las imágenes del libro tienen una calidad es excelente. Además, la calidad de impresión es lo que se esperaría de un libro de fotografía de alto perfil. Algunas de las especies más raras carecen de una imagen espectacular para representarla. ¡Probablemente no haya muchas fotografías de algunas de estas especies raras por ahí! Estas imágenes son un testimonio importante de lo poco que sabemos sobre algunas especies de águilas en el mundo.

¿Cuál te recomendamos?

Recomendamos con entusiasmo tanto “The Empire of the Eagle” como “Águila de Bonelli”. Son libros excelentes para cualquier persona interesada en la naturaleza y la vida salvaje. Especialmente, para los apasionados de uno de los grupos de animales más majestuosos: las aves rapaces. ¡Con la Navidad a la vuelta de la esquina, estos extraordinarios libros son el regalo perfecto!

Birding Northern Morocco: Trip Report

We recently finished a Birding Northern Morocco trip and just uploaded the trip report. You can find it here. It contains a full description of the itinerary, with pictures taken during the trip. It also has an annotated list of birds, mammals, reptiles, amphibians and insects! On this post we mention some of the highlights of this trip.

Birding Northern Morocco highlights

  • We found one of the targets, and in good numbers, almost right out of the plane. Seeing up to 11 African Royal Terns, a species recently split from the American Royal Tern, was certainly a highlight.
  • We got phenomenal views of one of the main targets of the trip: the Lanner Falcon. We had two adult Lanner Falcons at pleasure in our scopes, and also got great views of the birds in flight. That same morning we saw 2 Great Bustards from the last surviving population in Africa.
  • Seeing up to nine Marsh Owls at dusk near the Merja Zerga Lagoon was certainly one of the best moments of the tour.
  • The boat trip at Merja Zerga lagoon and the visit to a Eleonora’s Falcon colony provided excellent views and photography opportunities.
  • The Zaër Forest was productive after some work. We ended up seeing our three targets on site: Barbary Partridge, Double-spurred Francolin and Black-crowned Tchagra.
  • The visit to the old Roman city of Volubilis was a welcome addition to the trip.
  • A couple of Levaillant’s Woodpeckers provided some of the best experiences of the trip at Dayet Aoua.
  • We heard and saw the recently split Maghreb Wood Owl, closely related to the Tawny Owl. You can hear a recording of this bird here.
  • The Zaida Plains provided a welcome change of scenery. Here we found some desert specialties including one of our main targets: the Dupont’s Lark.

The most remarkable highlight of the Birding Northern Morocco trip was hitting all the targets while having a relaxed and friendly atmosphere. And let’s not forget the abundant and good food! This all made for a great trip to some of the most unexplored sites of Morocco.
