Records at the species range boundaries

Aug 31, 2018 / Comment

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 Short-toed Eagle by Liudmila Pozhidaeva on the Birds of Siberia websiteAt the opposite side of the range’s northern boundary, not far from Barnaul /map/, the administrative centre of the Altai Krai, a Short-toed Eagle was recorded this year too. 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.

 

A report on the rehabilitation of a Short-toed Eagle

Jun 30, 2018 / Comment

Although, this paper is rather old, it can be considered as a good example of a report on Short-toed Eagle rehabilitation. If all similar cases were described in such a detailed way, our knowledge on sexing and ageing of Short-toed Eagles would be much deeper:

We are continuing to collect various texts about Short-toed Eagle records and observations in various regions. Along records in modern online databases, they give the fuller patern of the species distribution and its evolution within recent decades:
