Circaetus gallicus information navigator

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 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).

The represented article contains the detailed history of records of Short-toed Eagles in Switzerland almost within a century of observations:

• Kéry, M. & B. Posse, 1998 – Auftreten des Schlangenadlers Circaetus gallicus in der Schweiz von 1900 bis 1993 [Distribution of the Short-Toed Eagle in Switzerland from 1900 to 1993] // Der Ornithologische Beobachter, 95: 39-54. – (De).

• Agostini N., Mellone U., 2008 – Does migration flyway of Short-toed Eagles (Circaetus gallicus) breeding in Central Italy reflect the colonization history? // Journal of Raptor Research, 42(2): 158-159. – (En).

We extend our thanks to Ugo Mellone for pointing the article out. It can be found among other papers on the Research section of his website.
