Circaetus gallicus in the Netherlands and Eastern Slovakia

Thursday, November 27th, 2014 / Comment

We try to check regularly appearing on the Web papers about Short-toed Eagle. Every freely accessible article is added to the collection, a kind of our library. Certainly, the majority of them aren’t new, but they are not of less interest due to this. The following ones can be viewed on websites of the journal of ornithology Tichodroma and of Sovon.nl, Dutch Centre for Field Ornithology:

• Štefan Danko, Jozef Mihók & Štefan Pčola, 2007 – Hniezdenie a výskyty hadiara krátkoprstého (Circaetus gallicus) na východnom Slovensku [Breeding and occurrence of the Short-toed Eagle in Eastern Slovakia] // Tichodroma 19: pp. 75–86. – Short-toed Eagle. file (Sk) /map/.

• Arjan Boele, Erik van Winden & Rik Winters, 2013 – Slangenarend en Noordse Nachtegaal nieuw in het BSP: van dwaalgast tot broedvogel? [Short-toed Eagle and Thrush Nightingale in the BSP: from accidental to breeding?] // Sovon-Nieuws, jaargang 26, nr 1: pp. 5-6. – Short-toed Eagle. file (Nl).

 

Short-toed Eagles in flight. Northern Ukraine. 2014

Saturday, November 22nd, 2014 / Comment
Fragments of Short-toed Eagles' flights in Northern Ukraine this year

These fragments of Short-toed Eagles’ flights have been shot at their breeding territories and hunting grounds in Kiev Region /map/ and in Mezhrechenskiy Park /map/ this year. The video is commented on, please, pay attention on subtitles. You can see eagles A11, B11, K11 and L11 in the clip. Certainly, also other more melodious names were given them for routine use. These STEs occupy their breeding sites within the same home ranges from year to year since at least 2006 and 2010. For a regular observer every bird has obvious individual traits. The video without compression can be downloaded.

The discovery of an ancient Circaetus in SW Bulgaria

Saturday, October 25th, 2014 / Comment

A fossil representative of the Circaetus genus was discovered in South-Western Bulgaria /map/. The birds had already lived in ancient Europe more than 7 millions of years ago; although, their origin from Africa is suggested as very probable. The paper is available on a website of the journal Acta zoologica bulgarica:

• Z. Boev, 2012 – Circaetus rhodopensis sp. n. (Aves: Accipitriformes) from the Late Miocene of Hadzhidimovo (SW Bulgaria) // Acta zool. bulg., 64 (1): pp. 5-12. – Short-toed Eagle. file (En).

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!
