Results of many years’ study of Short-toed Eagle biology in the south-western Kopetdag /map/ by Sergey Bukreev are presented in the following article:
• Букреев С.А., 1996 – Материалы по биологии туркестанского змееяда (Circaetus gallicus heptneri; Falconiformes Accipitridae) на юго-западном Копетдаге [Notes on the biology of Circaetus gallicus heptnery in the south-western Kopetdag] // Зоол. журн., т.75, вып.5. – С. 726-735. (Ru).
This article (Ru) written by Roald Potapov about Short-toed Eagle in southern Tajikistan /map/ was published for the first time in 1960:
• Потапов Р.Л., 1960 – К биологии орла-змееяда в южном Таджикистане [Notes on biology of the Short-toed Eagle in southern Tajikistan] // Изв. сель.-хоз. и биол. наук АН Тадж. ССР 1, 2: 135-137; and was republished in the Russian Ornithological Journal this year:
• Потапов Р.Л. – К экологии орла-змееяда Circaetus gallicus в южном Таджикистане [Notes on ecology of the Short-toed Eagle Circaetus gallicus in southern Tajikistan] // Русский орнитологический журнал 2009, Том 18, Экспресс-выпуск 518: 1789-1792. (Ru).
Thanks to Maxim Gavrilyuk for the pointing this republication out.
One of works of the oldest Short-toed Eagles researcher in France – Yves Boudoint /map/ – is represented below. This text describes some interesting details of biology of the species and includes notes on some traditional and untraditional methods of study:
