Returning of Short-toed Eagle to Poland

Migration birds of prey from Lublin region

After 153 days of silence GSM transmitter of the adult Short-toed Eagle female tagged in Poland in 2012 started working again in Africa on March 1st. So, Polish ornithologists could mark her spring migration route receiving coordinates of her location each hour. The route was different from the autumn one: the bird visited Greece and Ukraine where she was travelling during almost 3 weeks, maybe because of the bad weather conditions, but finally she achieved the old breeding territory in Poland /map/. Her partner was observed there on April 17th with caught snake in his beak. The female joined him 2 days later.

You can find more information about the project on the Lublin Ornithology Society website and you can see detailed descriptions of the Short-toed Eagle’s adventures on the LTO page in Facebook (Pl). Also please view the migration map:

Winter observations of Short-toed Eagle in Crimea

Feb 10, 2013 / 1 Comment

The following observations have been made for the first time in the history of studies in the Crimean Peninsula. The point, Cape Chauda /map/, is located strictly at the 45th parallel.

BESKARAVAYNYI M. 2012. Crimean PeninsulaWhile counting geese on Cape Chauda in the southern part of the Kerch Peninsula (Crimea, Ukraine) we have observed a young Short-toed Eagle (aged less than 1 year) on January 14, 2013. Then at the same location two individuals (male and female) in juvenile plumage too was observed on February 4, 2013. The birds were kept on a power pole surrounded by steppe.

Weather conditions in the autumn and winter of 2012/2013 years were soft, positive temperatures dominated, snowfall was rare and only for short periods. Observations in January and in February were made at above-zero temperature as well, snow cover was missing. Perhaps such weather conditions have caused Short-toed Eagles’ wintering in Crimea.

Possible prey items on Chauda: Steppe Viper (Vipera renardi); the snake is common there, but in warm winters can be active and can appear on the surface of the ground – we have seen them in previous winters; also voles couldn’t be excluded.
