Records at the species range boundaries

Aug 31, 2018 / Comment

Immature Short-toed Eagle in UK in 2014, by Roger StarbuckSeveral records of Short-toed Snake Eagle at the boundaries of the species range were reported this summer. Local birders informed about observation of an eagle again in the United Kingdom, at Ashdown Forest /map/ in East Sussex: it was seen several times since June 21st. Unfortunately, the age of that bird has remained unknown. Four years earlier, a young Short-toed Eagle had been observed at Morden Bog /map/, near Wareham.

Photos of Short-toed Eagle by Liudmila Pozhidaeva on the Birds of Siberia websiteAt the opposite side of the range’s northern boundary, not far from Barnaul /map/, the administrative centre of the Altai Krai, a Short-toed Eagle was recorded this year too. Photos of an adult Short-toed Eagle female by Askar Isabekov on the Birds of Kazakhstan websitePhotos of it are available on the Birds of Siberia website. This time it was an adult bird, as well as the previous one observed in 2016. Also, this summer has brought many encounters with ST Eagles to birders in Kazakhstan, just enjoy the pictures.

 

Short faunistic notes: CE Belgium and NE Italy

We are continuing to collect various texts about Short-toed Eagle records and observations in various regions. Along records in modern online databases, they give the fuller patern of the species distribution and its evolution within recent decades:

• Giacomo SGORLON, 2016 – Estivazione del Biancone Circaetus gallicus nella pianura Veneta Orientale [Summering of a Short-toed Eagle in the Eastern Veneto plain] // Uccelli d’Italia, 41: 150-152. – Short-toed Eagle. file (It) /map/.

• Lurent-Henry GÉE, 1989 – Séjour d’un Circaëte Jean-le-Blanc (Circaetus gallicus) en Meuse hutoise en juillet-aout 1988 [Stay of a Short-toed Eagle near the Huy City and the River Meuse in July-August 1988] // Aves, 26/3-4: 205-206. – Short-toed Eagle. file (Fr) /map/.

Two articles on Short-toed Eagle available online

We wrote about these two papers (López-Iborra et al., Yáñez et al.) after they had been published. Now full texts of them are available as well:

• G. M. López-Iborra, R. Limiñana, D. Pavón and J. E. Martínez-Pérez, 2011 – Modelling the distribution of Short-toed Eagle (Circaetus gallicus) in semi-arid Mediterranean landscapes: identifying important explanatory variables and their implications for its conservation // European Journal of Wildlife Research, 57: pp. 83-93. – Short-toed Eagle. file (En).

White Short-toed Eagle fledgling in Spain in 2013

Nov 22, 2015 / 1 Comment

EL ÁGUILA BLANCA (Circaetus gallicus)This bird had been photographed by Javier G. in Peñaflor (the environments of Zaragoza city, Spain) /map/ in August 2013. Thanks to the author and to Javier Blasco-Zumeta we have the following information about that unique record of leucism in Short-toed Snake Eagle:

That absolutely white bird was born in a forest of Aleppo pine (Pinus halepensis), successfully left the nest, was observed in its territory until the end of September, and when it was time to start the migration the juvenile Short-toed Eagle flew away.

If the bird has survived, its return to Europe may be expected next year, after 2 years of probable wintering and summering in Africa.

Two more articles on migration of Short-toed Eagles came out this year:

Mellone U., Klaassen R.H.G., García-Ripollés C., Limiñana R., López-López P., Pavón D., Strandberg R., Urios V., Vardakis M., Alerstam T., 2012 – Interspecific comparison of the performance of soaring migrants in relation to morphology, meteorological conditions and migration strategies // PLoS ONE 7(7): e39833. doi:10.1371 / journal.pone.0039833 – Short-toed Eagle. file (En).

The first one is based on comparative data concerning Osprey, Marsh Harrier, Egyptian Vulture and Short-toed Eagle.
