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.

The amazing migration of the Judean Short-toed Eagle. Video by Guilad Friedemann (available in HD quality)

One more contribution from Guilad Friedemann. This time it is a video presentation. Using Google Earth tools Guilad invites us to follow David, one of the Short-toed Eagles tagged with the special GPS-loggers, from his home range in the Judean Foothills /map/ to the wintering grounds in Sudan. The virtual tour on his migration route is amazing!

Winter observations of Short-toed Eagle in Crimea

Feb 10, 2013 / 1 Comment

The following observations have been made for the first time in the history of studies in the Crimean Peninsula. The point, Cape Chauda /map/, is located strictly at the 45th parallel.

BESKARAVAYNYI M. 2012. Crimean PeninsulaWhile counting geese on Cape Chauda in the southern part of the Kerch Peninsula (Crimea, Ukraine) we have observed a young Short-toed Eagle (aged less than 1 year) on January 14, 2013. Then at the same location two individuals (male and female) in juvenile plumage too was observed on February 4, 2013. The birds were kept on a power pole surrounded by steppe.

Weather conditions in the autumn and winter of 2012/2013 years were soft, positive temperatures dominated, snowfall was rare and only for short periods. Observations in January and in February were made at above-zero temperature as well, snow cover was missing. Perhaps such weather conditions have caused Short-toed Eagles’ wintering in Crimea.

Possible prey items on Chauda: Steppe Viper (Vipera renardi); the snake is common there, but in warm winters can be active and can appear on the surface of the ground – we have seen them in previous winters; also voles couldn’t be excluded.

Wintering in Spain and habitat in Greece

Mar 23, 2006 / 1 Comment

Here you can acquaint yourself with the work on the wintering of Short-toed Eagle and Booted Eagle in Spain:

• José Enrique Martínes y José Antonio Sánchez-Zapata, 1999 – Invernada de Aguililla Calzada (Hieraaetus pennatus) y Culebrera Europea (Circaetus gallicus) en España [Wintering of Booted Eagles and Short-toed Eagles in Spain] // Ardeola 46 (1): 93-96 – Short-toed Eagle. file (Es) (source – Ardeola website).

…and with the abstract of an article about Greek Short-toed Eagles:
