Comparative studies of migration and distribution

Dec 8, 2018 / Comment

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:

Staying in N France and migration in S Turkey

Two Short-toed Eagles together, Brassoir - 2016 / by Rémi MalignatHenry de Lestanville describes in his paper staying of 2 Short-toed Eagles at Brassoir in summer 2016 and the current status of the species in Picardy /map/:

• Henry DE LESTANVILLE, 2018 – Stationnement de deux Circaètes Jean-le-blanc Circaetus gallicus à Brassoir en 2016 [Staying of two Short-toed Eagles at Brassoir in 2016] // Avocette, 42 (1) – Revue naturaliste de Picardie Nature: pp. 3-8. – Short-toed Eagle. file (Fr).

An impressive number of ST Eagles migrating at Sarimazi, Southern Turkey /map/, in autumn 2018 is reported on the Egyptian Vulture New LIFE site: 10853. This raises a lot of questions about real strength of their streams from Eastern Europe. Many thanks to Gábor Papp for sharing!

 

Short-toed Eagle research projects in Croatia

Sep 30, 2018 / Comment

The following paper by Ivan Budinski established principles of the local Short-toed Eagle population monitoring program in Croatia:

• Ivan BUDINSKI, 2014 – Nacionalni program za monitoring zmijara (Circaetus gallicus) [National monitoring program for Short-toed Eagle] // Udruga BIOM. Zagreb: 10 p. – Short-toed Eagle. file (Hr).

The author is one of Croatian researchers involved in the project of GPS tracking of Paško, the local young Short-toed Eagle. The map of the bird’s migratory movements is available online and regularly updated.

 

GPS-GSM tracking of Short-toed Eagle in Croatia

GPS-GSM tagging of Short-toed Eagles in Hungary

Oct 14, 2017 / Comment

Within the framework of the Turjánvidék LIFE project, which aims the preservation of habitats of such species as the endangered Hungarian Meadow Viper (Vipera ursinii rakosiensis), two Ecotone GPS-GSM trackers were bought in 2016. The main aim was to follow the life of a Short-toed Eagle pair residing close to and hunting regularly on viper habitats. Since the capture of the adult male failed in 2017, experts marked the offspringÖrs on SATELLITETRACKING.EU of this pair with the transmitter /map/. The chick was named Örs, an ancient Hungarian name meaning «human», «man» or «hero» but also a name of a Hungarian tribe from ancient times.

Örs left the natal area on October 1st and its tracks can be followed on SATELLITETRACKING.EU.

The other transmitter was deployed on a repatriated individual in 2016, which died two months later in Poland. Its tracks are not available on the aforementioned website yet, however, another post will appear here if so.
