A new article written by Dimitris E. Bakaloudis by results of researches of Short-toed Eagle in Greece /map/ is put now on the Ornis Fennica site. You can find it among a few other works on the Online early section:
• Dimitrios E. Bakaloudis, 2009 – Implications for conservation of foraging sites selected by Short-toed Eagles (Circaetus gallicus) in Greece // Ornis Fennica 86:89–96. – 
(En).
Two articles have been discovered on the Net:
• D.E. Bakaloudis, C.G. Vlachos, G.J. Holloway, 2000 – Nest features and nest-tree characteristics of Short-toed Eagles (Circaetus gallicus) in the Dadia-Lefkimi-Soufli Forest, Northeastern Greece // Raptor Res. 34(4): 293-298. – (En) /map/ (source – www.researchgate.net).

We extend our thanks to Ugo Mellone for pointing the article out. It can be found among other papers on the Research section of his website.
You can find an article of Christos G. Vlachos on the University of New Mexico. University Libraries website. The work was dedicated to Short-toed Eagle ecology in North-Eastern Greece /map/:

Let us draw your attention to a work of Dimitris E. Bakaloudis, Christos G. Vlachos and Graham J. Holloway on Short-toed Eagle in northeast Greece /map/:

If you are interested in some documents on Short-toed Eagles in Russian you should visit a website of the Working Group on Raptors of Northern Eurasia. We have told about this resource several times. The main subsection of the site is free electronic texts database, where you can raise a query for Circaetus and get the result as a list of texts dedicated to the species and also of texts with mentions of it (Ru)(En). There are 35 documents on Short-toed Eagle in all at the moment.
