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.

Kunal Kambli in his recent post for The Weather Channel writes that Short-toed Eagle is among the species whose populations in India have declined in last years according to:

• SoIB 2020. State of India’s Birds, 2020: Range, trends and conservation status. The SoIB Partnership. Pp 50. – (En).

Unlike others, the population of Short-toeds in India is settled. Although, there are no more or less exact evaluations of its current size, it is undoubtedly significant, and the species is under highest legal protection in the country. However, the short- and long-term negative trends are ascertained on the background of the global population trend estimated as stable. This is a kind of unpleasant surprise and causes of the local population decline deserve to be figured out and analysed in details.

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.

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.

The total scale of collected data in the journal of the ST Eagle national monitoring program in France is amazing and deserves special attention (Fr):

Thanks a lot to Renaud Nadal for sharing that remarkable review!

A lot of information about observations and data on the current state of Short-toed Eagle population in the Isère Department /map/ are available on the LPO Mission rapaces and Faune Isère sites. Foremost, the following article by Françoise Chevalier deserves a particular attention:

• Françoise CHEVALIER, 2014 – Quatorze ans de recherche et de suivi des couples de circaète Jean-le-Blanc Circaetus gallicus dans le sud-est du département de l’Isère [Fourteen years of research and monitoring of Short-toed Eagle in the southeast of the Isère Department] // Le Bièvre, tome 26: pp. 26-33. – (Fr).
