Circaetus gallicus information navigator

The regular annual review of Short-toed Eagle monitoring in the Alpes de Haute-Provence /map/ coordinated by Cédric Arnaud:

• Cédric ARNAUD, 2015 – Suivi du Circaète Jean-le-blanc dans les Alpes de Haute-Provence. Petit coup d’œil en arrière : résultats du suivi pour l’année 2015 [Monitoring of Short-toed Eagle in the Alpes de Haute-Provence. Results for 2015]: 19 p. – (Fr) {rough translation}.

The list of contents (Fr): Résultats du suivi 2015 – 3; Suivi de la reproduction – 6; Régime alimentaire – 10; Migration et dates de présence – 11; IInterventions d’information, de sensibilisation et d’échanges – 12; Centre de soins de la faune sauvage 04-05 Aquila – 12; Observations particulières – 13; Bases de données et sites de saisies de données en ligne – 15; Participants – 16; Campagne de suivi & objectifs 2016 – 17; Site de saisie de données en ligne en 2016 – PNRV – 18; Résumé – 19.

The presented work is available on a website of the Electronic Theses & Dissertations Center. It is based on unique research data of Guilad Friedemann collected in period of 2011-2014. The main goal of the work was detection of the correlation between various environmental factors and migratory movements of Short-toed Eagles and Long-legged Buzzards of the Judean Foothills’ populations /map/:

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. – (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).

The 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.

The following two texts are dedicated to notable physical abilities of Short-toed Eagles and, like the previous one of Bernard Joubert, are going to be included in the next issue of La Plume du Circaète (Fr):

• Bernard JOUBERT, 2015 – Performance visuelle du Circaète [Visual abilities of Short-toed Eagle] // short-toed-eagle.net.

• Bernard JOUBERT, 2015 – Quelques réflexions sur le vol [Some reflections on the flight] // short-toed-eagle.net.

The articles about Short-toed Eagles in present southwestern /map/ and southeastern /map/ Poland are divided by about 80 years. Four of them, written by Viktor Zebe /map/ and published in the first half of the 20^th century, have been placed on the Ptaki Śląska – Birds of Silesia website (De):

The next paper by Adam Flis is available on a website of the Institute of Nature Conservation PAS:

• Adam FLIS, 2013 – Występowanie gadożera Circaetus gallicus w Lasach Janowskich i Lipskich [The occurrence of Short-toed Eagle in Janowskie and Lipskie Forests (SE Poland)] // Chrońmy Przyrodę Ojczystą, 69 (3): pp. 221–225. – (Pl).

Returning to the important topic of correct identification of differently aged Short-toed Eagles in the nature, Gábor Papp has tried to briefly describe the main characters of juvenile, 2, 3 and 4 cy eagles, and also visual differences between adult males and females. His description are illustrated with the corresponding images. Here is two versions of the text, Hungarian and English ones:

• Gábor PAPP, 2015 – A kígyászölyv kor és ivarhatározása – segédlet a terepi megfigyelések minőségének javításához [Ageing and sexing of the Short-toed Eagle – an aid to improve the quality of field observations in Hungary] // short-toed-eagle.net – (Hu), (En).

This bird had been photographed by Javier G. in Peñaflor (the environments of Zaragoza city, Spain) /map/ in August 2013. Thanks to the author and to Javier Blasco-Zumeta we have the following information about that unique record of leucism in Short-toed Snake Eagle:

That absolutely white bird was born in a forest of Aleppo pine (Pinus halepensis), successfully left the nest, was observed in its territory until the end of September, and when it was time to start the migration the juvenile Short-toed Eagle flew away.

If the bird has survived, its return to Europe may be expected next year, after 2 years of probable wintering and summering in Africa.
