An impressive number of ST Eagles migrating at Sarimazi, Southern Turkey /map/, in autumn 2018 is reported on the Egyptian Vulture New LIFE site: 10853. This raises a lot of questions about real strength of their streams from Eastern Europe. Many thanks to Gábor Papp for sharing!

Immature Short-toed Eagle in UK in 2014, by Roger StarbuckSeveral records of Short-toed Snake Eagle at the boundaries of the species range were reported this summer. Local birders informed about observation of an eagle again in the United Kingdom, at Ashdown Forest /map/ in East Sussex: it was seen several times since June 21st. Unfortunately, the age of that bird has remained unknown. Four years earlier, a young Short-toed Eagle had been observed at Morden Bog /map/, near Wareham.

Photos of an adult Short-toed Eagle female by Askar Isabekov on the Birds of Kazakhstan websitePhotos of it are available on the Birds of Siberia website. This time it was an adult bird, as well as the previous one observed in 2016. Also, this summer has brought many encounters with ST Eagles to birders in Kazakhstan, just enjoy the pictures.
