Materials on the breeding biology of Short-toed Eagle for Alexander Abuladze‘s thesis (Ru) were collected since 1973 on a territory of Georgia and of Western Azerbaijan:
• А. В. Абуладзе, 2006 – Змееяд (Circaetus gallicus) [Raptors of Georgia. Short-toed Eagle (Circaetus gallicus)] – Хищные птицы Грузии : Дисс … канд. биол. наук. – Тбилиси. – С. 87-91 (208 с.).
You can find the full text of the thesis on a website of the National Parliamentary Library of Georgia.
These photos were taken in the national park "Smolenskoe Poozerje" /map/ by Marina Sidenko in 2009-2010 years. Two Short-toed Eagles’ nests were found there at the same nesting site. Many thanks to Marina for the comments on every picture!
The following note of Viktor Belik is published in the 8th volume of the «Strepet» ornithological journal:

Intraspecies communication and contest behaviour
For 3 hours, the 24th March 2010, I am the witness of a specific behavior between a male and an intruding female. The scene takes place on a nest, two weeks before the laying-date. At first, the male “marks” his site ostensibly. An unknown female, interested by the nest appears …

New interview about the biology and current conservation situation of Short-toed Eagle in Italy has been given by Francesco Petretti. Like two previous interviews about Short-toed Eagles it is published on the Interviews section of the European Raptors website.
