This video is a compilation of various short parts of the filming
done in Northern Ukraine during the last year’s season from spring to fall. The shown moments of Short-toed Eagles’ life are provided with explanatory subtitles. The second part of the annual photo gallery contains descriptions of behaviour and habits of local STEs as well. Please see them under each presented picture.

Two articles on Short-toed Eagle available online
Jan 19, 2016 / CommentWe 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:

Reproduction of certain pairs within 10 years in Ukraine
Oct 31, 2015 / Comment
How different reproduction of different pairs can be? Some adult Short-toed Eagles occupy the same sites from year to year. They had yet been identified in 2011 by photos taken since 2006 and according to previous and new observations. The birds had got indexes A11, B11 etc. although, in spoken communication we give them more harmonious names: for example, K11 is Barry, B11 is Ospry, and so on. Then later pictures of the individuals repeatedly got into the annual photo galleries. The natural identifying details are general plumage patterns,
shapes of heads, wings, beaks and general silhouettes in flight from certain angles as well as signs of moulting. The number of the examined images should be enough to select the details and to collate them. Thus, now it is possible to compare the mean reproduction – – of pairs of individuals identified from year to year for certain, definitely without replacements of mates and without clear differences in objective conditions for breeding.
