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 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.

More historical data about Short-toed Eagles in Switzerland can be found on a webpage of the journal Ornithologische Beobachter:

• Karl Daut, 1910 – Seltenere Vertreter der schweizerischen Avifauna. Der Schlangenadler – Circaetus gallicus (Gm.) [A rare representative of the Swiss avifauna. Short-toed Eagle] // Der Ornithologische Beobachter, VIII (1): pp. 1-3. – Short-toed Eagle. file (De).

The former and present state of the species in the Canton of Valais /map/ is described in the communication, published this year:

Lionel Maumary, 2015 – Nouvelle nidification du Circaète Jean-le-Blanc en Valais [New nesting of Short-toed Eagle in Valais] // Oiseaux.ch (Fr).

Ornotho.ch search results for Circaète Jean-le-BlancThe following web resource deserves to be mentioned again: the map of the sighting locations is available for the registered contributors of Ornitho.ch only. However, any visitor of the site can view the photo gallery. The most of the pictures of Short-toed Eagles represented there have been taken in Switzerland.

Circaetus gallicus by Oksana Raldugina on uabirds.org

The new birding database has been created this year for collecting pictures, geographical locations and other data of observations from Ukrainian birdwatchers. Among information on other species, it contains details of new records of Short-toed Eagles in various regions of Ukraine. The site has been made by Askar Isabekov and Andrew Simon as an analog of the well-known project for Kazakhstan that has already existed for 10 years. One more similar website is dedicated to Siberian birds. There is not any record of Short-toed Eagle on the last one yet; nevertheless, even isolated observations made at the edge of the species range would be of the great interest for ST Eagle researchers.
