Circaetus gallicus information navigator

The following articles have been published online this month. In the first one Ugo Mellone summarizes and analyzes results of many years of research on the migration of birds of prey through and around the Mediterranean Sea. The pattern of most circuitous migration route is exhibited by Short-toed Snake Eagle:

• Ugo MELLONE, 2020 – Sea crossing as a major determinant for the evolution of migratory strategies in soaring birds // Journal of Animal Ecology, 89 (6): pp.1298-1301. doi:10.1111/1365-2656.13241 (En).

The next paper is dedicated to the complex roadkill study. Unexpectedly, STE gets on the top 10 of the most vulnerable species of Europe:

The Batumi Raptor Count monitors the autumn migration of more than 1 million raptors including thousands of ST Eagles along the eastern Black Sea coast in Georgia at the Batumi bottleneck /map/.

Also, other publications are available at the BRC site.

Gábor Papp has collected and summarized information about colour-ringing of Short-toed Eagles in Hungary. The program has been continued for 7 years. The current numbers of ringed eagles, observations and photographing of the birds, prospects of new resightings are described in the communication:

The following papers about Short-toed Eagle mentioned on HoverOverUs before have recently appeared on ResearchGate portal in free access:

The annual review of Short-toed Eagle monitoring in Cévennes National Park /map/ and Lozère contains the latest data and unique observations:

• Jean-Pierre et Isabelle MALAFOSSE, 2018 – Le Circaète Jean-le-Blanc, résultats pour 2018. Suivi des Rapaces forestiers en Lozère et dans le Parc National des Cévennes [Short-toed Eagle, results for 2018. Monitoring of Raptors in Lozère and in the Cévennes National Park], rapport interne C.R.B.P.O./ P.N.C.: 12 p. – (Fr), (En) {rough translation}.

Many thanks to the authors and translators (Ferenc and Gábor Papp)!

The authors of the following papers studied Short-toed Eagles among other Raptors. Here are the results of those comparative studies focused on monitoring of migrating birds and on distribution constraints:

Diet and breeding site characteristics of six different raptor species, including STE, in Central India are compared in the following article:

• Satish PANDE, Reuven YOSEF, Federico MORELLI, Rajkumar PAWAR and Ram MONE, 2018 – Diet and habitat affinities in six raptor species in India // Avian Research, 9:36. doi:10.1186/s40657-018-0129-2 – (En).

That is a region where Short-toed Snake Eagles have potential food competitors. Besides, data on their diet and habitats in the Indian part of the distribution area are of great interest in themselves.
