Circaetus gallicus information navigator

The long field research on two raptors Short-toed Eagle and Long-legged Buzzard in the Judean Foothills /map/ allowed Guilad Friedemann to prepare his PhD Thesis which was published a few years ago:

• Guilad FRIEDEMANN, Yossi LESHEM, Ido IZHAKI, 2016 – Multidimensional differentiation in foraging resource use and competitive interactions over nesting sites between two sympatric top predators – PhD.Thesis: 104 p. – (En).

The document available at ResearchGate also contains articles published earlier and already covered on our site.

The research continues and we are looking forward to new broadcasts, videos and papers shared by the Israeli team.

Askar Isabekov has merged data from different birdwatching websites on the Birds of Northern Eurasia portal. This database allows to monitor appearing new pictures and observations of various bird species in several countries of Northern Eurasia, including Short-toed Eagles. At least 3 out of currently 12 regional sites were mentioned on HoverOverUs before.

Several 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 21^st. 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.

At 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 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.

The recently accepted article of Guilad Friedemann and others is a result of the study of interspecific interactions between Short-toed Eagles and Long-legged Buzzards and their breeding in the Judean Slopes /map/:

• Guilad FRIEDEMANN, Yossi LESHEM, Lior KEREM, Avi BAR-MASSADA & Ido IZHAKI, 2017 – Nest-site characteristics, breeding success and competitive interactions between two recently sympatric apex predators // Ibis. Accepted Author Manuscript. doi:10.1111/ibi.12498; the Supplementary online material – (En).

Results of a comparative study of using foraging resources by Short-toed Eagles and Long-legged Buzzards in the Judean Foothills /map/ are reported in the following fresh article of Guilad Friedemann & others:

• Guilad FRIEDEMANN, Yossi LESHEM, Lior KEREM, Boaz SHACHAM, Avi BAR-MASSADA, Krystaal M. MCCLAIN, Gil BOHRER & Ido IZHAKI, 2016 – Multidimensional differentiation in foraging resource use during breeding of two sympatric top predators // Scientific Reports 6. doi:10.1038 / srep35031 – ; the Supplementary information – (En).

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.

Let’s thank Guilad Friedemann for sharing the following article based on data of his studies in the Judean Foothills /map/:

Mumcuoglu, 2013 – Alternative nest-building behavior of the Long-legged Buzzard (Buteo rufinus) and the Short-toed Eagle (Circaetus gallicus) in the Judean Foothills, and the parasitic and non-parasitic arthropod fauna in their nests // Israel Journal of Entomology, Vol. 43: pp. 11-19. – (En).
