We are backing a conservation project to save the Montagu’s Harrier in La Janda, in the Strait of Gibraltar. As some of you know, the numbers of Montagu’s Harriers in the region have plummeted dramatically, mainly due to change in agricultural practices and habitat destruction.

Our friends from the association Tumbabuey are working hard to preserve the population of Harriers and make it grow in the long term, with combined actions that include sustainable farming that favor the species.

If you want to contribute to this good cause it’s really easy, just follow this link to go to the crowdfunding website. There are nice rewards for those who contribute, but most importantly, you will be a fundamental part of this project!

We encourage all our friends to participate and help these magnificent raptors!

Beyond the Strait: Canarian endemics birding trip 2017!

In Birding The Strait we feel an special attraction for the landscapes and wildlife of the Canarian Archipielago. Indeed, this is one of our preferred destinations when not birding in Tarifa.

In early April we have been pleased to design and guide a tailor made birding trip combining Tenerife (3 days) and Fuerteventura (4 days) with an evident target: observing and photographing  the local endemics and specialities. We have beautifully meet all our targets, including some bonus in the form of 5 striking Red-billed Tropicbirds off Fuerteventura!

This is a selection of our best shots:

Houbara Bustard (ssp. fuerteventurae) in the astonishing planes of Tindaya , Fuerteventura.
The Blue Chaffinch (Fringilla teydea) is now considered a full species and has been splitted from the Gran Canaria Blue Chaffinch (F. polatzeki). These are, no doubt, among the most striking Canarian endemics.
The dark brown chest is the most distinctive character in the Canarian endemic subspecies of the Greatter spotted woodpecker (ssp. Canariensis)
The taxonomic rank of the Canarian falcons is under debate and many individuals should be considered intergrades between Barbary and Peregrine. The male in the picture, photographed in Fuerteventura, showed all the correct characters of a Barbary Falcon.
The Fuerteventura Stonechat shows a marked preference for the rocky slopes of the “Barrancos” and, amazingly, is not present in the neighbouring Lanzarote.
Photographing Common Ravens is often tricky, except when you meet the inquisitive canariensis subspecies.
Even if not endemic, the Trumpeter Finch is always a joy for the observers and photographers.
At times elusive, a displaying pair of Laurel Pigeons in Tenerife was a real highlight in the trip.
Adult “Fuerteventura” Buzzard showing obvious resemblance to the Atlas Long-legged Buzzards in Morocco and notably different to average individuals of the insulaum subespecies in Tenerife. Indeed, Buzzards of the local population in Fuerteventura have often been misidentified as Long-legged.

In perfect timing with this tour, the April 2017 issue of British Birds published a paper on the identification of the Buzzards in the Canary Islands on which we have contributed as co-aouthors and photographers.

Amazing numbers of Black Kites!

During the spring migration we get large concentrations of Black Kites, the most abundant migratory raptor in Western Europe, in the Strait of Gibraltar.

This short video from early March, shows impressive numbers of these raptors passing by before continuing their journey to their breeding grounds.

During migration, whenever easterly gales blow in the Strait, hundreds of raptors interrupt their journey and seek shelter on the sloping hillsides of Los Alcornocales Natural Park,  gathering in large communal roosts which do not occur elsewhere in Europe. Preserving this forest and securing the tranquility of the roosts is of paramount importance.

Birding The Strait in 2017 FIO International Birdfair

Birding The Strait has been present at 2017 FIO International Birdfair in Extremadura. We attended the stand of Andalusia on behalf of the Tarifa Council, participated in a professional workshop with international touroperators and gave a lecture titled “The migration of the Iberian Griffon Vultures to Africa, an overlooked wonder”.

Indeed, the  Griffon Vulture Migration is one of the most genuine experiences we offer and vulture study has constituted an important part of our carriers as field ornithologists in the Strait of Gibraltar and beyond.

During the lecture we reviewed what is known and what remains unknown on this still poorly studied phenomenon and highlighted the spectacularity of immense flocks of griffons crossing the Strait of Gibraltar.

One of the pictures included in the lecture, showing the massive concentration of Griffon Vultures in Tarifa during their autumn migration to Africa accros the Strait of Gibraltar.

It was a real honour to share the stage with our good friend Fernando Barrios, pioneer ornithologist and wildlife photographer in the Strait of Gibraltar and author of the reference work “Nomads of the Strait of Gibraltar“. He gave an authoritative lecture on the White-rumped Swift based on the research he conducted in the Strait of Gibraltar during the last decades of the previous century, when this African species colonized the European continent.

During the rest of this fabulous weekend we took the opportunity to do some birding in the always amazing Monfragüe National Park and the Plains of Caceres around Trujillo, where we easily found the local specialities, including Cinereous Vulture, Great Bustard, Little Bustard, Pin-tailed Sandgrouse and Black-bellied Sandgrouse.

Back in Tarifa, the first groups of Griffon Vultures crossing the Strait back from Africa have already been recorded along with thousands of Black Kites, growing numbers of Short-toed Eagle, Egyptian Vulture and Black Stork.

Two very special wintering Ospreys

Last 14th of January, the second edition of the Osprey Day was held in Andalusia. This event is promoted and coordinated by Amigos del Águila Pescadora (Friends of the Osprey), and comprises the Wintering Ospreys Count in Andalusia. Remarkably, over 100 observers and 15 entities participated, and Birding The Strait was pleased to be one of them for the second consecutive year.

As shown in the following figure, a total of 160 individuals (137 in 2016) were recorded, showing a marked western distribution. Indeed, nearly 50% of the individuals were found within Cádiz province. Among them, 20 Ospreys have chosen the reservoirs, rivers and the coastline of the Strait of Gibraltar as wintering quarters this year.

Among the later, two individual Ospreys deserve special attention. One of them is an adult Corsican female which we have been delighted to observe and photograph in our region over the last four winters. This bird was fitted with a green colour ring white code CAT and a GPS device in the Mediterranean island by Flavio Monti. This link to Movebanks shows the spectacular migration of CAT over the sea from her breeding site in Corsica to the Strait of Gibraltar in the autumn 2013 and back in the spring 2014 (following a route south of the Balearic Islands).

Coincidentally, CAT has been sharing part of his wintering ground in the Strait of Gibraltr with Beatrice, a very special Osprey that Roy Dennis fitted with a satellite tracking device in 2008 in Scotland. In autumn 2011 Roy Dennis and a team from the BBC Autumnwatch visited the Strait aiming to film Beatrice. Javi, that time working for Fundación Migres, was pleased to be their guide and took them to the river section where the Scottish Osprey was most regularly seen. Sadly, in March 2016 Beatrice died in Northern Spain because she could not catch fish in the swollen rivers caused by a long period of heavy rain. Beatrice has left a huge legacy on which we will write in a future blog post. Likewise, the Osprey migration across the Strait of Gibraltar and the successfully reintroduced breeding population will be future subjects on the Birding The Strait blog. Stay tuned!

Photographing large Eagles in Andalusia

“Autumn” (July-October) and “Spring” (February-May) are the periods when massive numbers of raptors cross Andalusia on migration to and back from Africa. However, Winter time, when migrant raptors are South of the Sahara, is probably the best momment to enjoy the largest, non migratory and iconic eagles of Spain, namely Golden, Bonelli´s and Spanish Imperial Eagle.

A significant number of juvenile and immature eagles from all over the Iberian Peninsula disperse South and reach Andalusia. Here, they concentrate in regions where food sources are abundant. This is the case of the Bonellí´s Eagle. Indeed, up to 15 (!) different individuals have been recorded simultaneously in La Janda, the Strait of Gibraltar, in previous weeks.

Adult eagles, released now from the chick rearing duties, get engaged in a new breeding season. This way, in January eagles become notaby showy while performing spectacular aerial courtship displays around their territories. This often leads to aggressive interactions, specially when an intruder enters an active breeding territory.

The following video shows the reaction of a pair of adult Spanish Imperial Eagles when they detect the presence of an immature Golden Eagle within their home range (set it to HD).

Furthermore, over the last winters, an unprecented presence of Lesser and Greatter Spotted Eagles has been recorded in La Janda region. If this were not enough, hybrids between both species have been observed as well, and an adult Steppe Eagle is overwintering in the same area!

Beyond La Janda, we have been recently testing different photography hides in Sierra Morena, Central Andalusia. This has been a very successful experience full of great observations and pictures!  Photographing large Eagles from hides is a perfect addition to our wildlife photography trips and courses in the Strait of Gibraltar.

The following pictures show part of our work . The comfort and reliability of these hides are unquestionable. Feel free to contact Birding The Strait if you want to enjoy this ultimate wildlife photography experience in Andalusia.
