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 specialized 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. – (Sk) /map/.

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.
These articles were published in 2012-2013. They all are dedicated to studies of migration of Short-toed Eagles. Now the full texts can be found on a site of Mediterranean Raptor Migration Network, on the section of papers:

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. – (En).
The northern part of Chernigov Region, so-called the Chernigov Polesye /map/, is one of the best regions of Ukraine for Short-toed Eagles’ habitation. These lands, rich in Grass Snakes, Vipers, other reptiles and also in old pine forests, provide the eagles with good conditions for foraging and nesting. An expert in Ukrainian birds of prey, Sergey Domashevsky, during the expedition in 2009 has recorded several probable territorial pairs of the eagles there. Some of them were observed between the Sozh, the Dnieper rivers and Zamglay Bog /map/.
This year a local birdwatcher, Artem Skeeter, has found Short-toed Eagles’ nest at a place where he saw them during a few years before. Artem has discovered the nest just after finding of one old tail feather under a perch at the breeding site. He has managed to take a video of feeding the juvenile eagle by its father on a pine within the site. Also photos of the birds have been taken there in 2011-2012 and this year by Artem and by Andrew Simon, Viktor Moroz and me. This year’s juvenile could already fly on August 9. The date is the earliest known in Northern Ukraine for the last 10 years. On September 9 another juvenile Short-toed Eagle, judging by all, an offspring of the neighbour pair, was observed in the hovering flight over typical hunting grounds far from forests, that is unusually early for this region too.
Two new works of Short-toed Eagle researchers are available on the Web now. Please, find the abstracts on the following pages:
