Life of Short-toed Eagles in photos by Bernard Joubert

February 19th, 2017 / Comment

JOUBERT B. 2010-2016. Haute-LoireThese amazing pictures and text were published in the latest La Plume du Circaète. Few of them were included in the previous galleries of Bernard Joubert on our site. Then, several new photos taken in March 2016 have been added and described by the author. Many thanks to him for sharing the pictures and especially for detailed comments on them, also to Ferenc and Gábor Papp for their kind help in the translation!

Moments of life

During these 20 years, while we have been following the Short-toed Eagles, we could obtain numerous pictures taken in ideal conditions, some of which we later published, however, I never played with the thought seriously that I should take advantage of it since photography is very laborious and has little use in conservation.

Nevertheless, in 2010, I decided that I would give it a try at a nest site where I could do it without any disturbance. In January, I built a hide, which I dug in the ground about twenty metres from the nest. I made a frame of beech and covered it with smaller pine branches. This nest site seemed to attract this particular pair, they visited it during last autumn several times.

I made myself comfortable in the hide in the first days of March, not knowing how remarkable moments and wonderful events of the everyday life I would experience soon.

I used a quite mediocre Nikon camera with 110 mm equivalent focus length*, but still I could record their whole breeding cycle except incubation without being noticed by them.

I would like to share a few pictures…

Short-toed Eagles in Isère. Reviews and galleries

March 20th, 2016 / Comment

Les galeries : Circaète Jean-le-BlancA 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. – Short-toed Eagle. file (Fr).

Also, please refer to the latest annual review:

• Françoise CHEVALIER, 2015 – Circaète Jean-le-Blanc Circaetus gallicus. Etude et suivis en Isère (38). Bilan 2015 [Short-toed Eagle. Research and monitoring in Isère. Summary for 2015] : 4 p. – Short-toed Eagle. file (Fr).

 

Aging and sexing of ST Eagles in the nature

December 7th, 2015 / Comment

A typically coloured adult Short-toed Eagle female, photo by András KovácsReturning 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.netShort-toed Eagle. file (Hu), Short-toed Eagle. file (En).

 

Data on Short-toed Eagle in new birding DBs

October 28th, 2015 / Comment
Circaetus gallicus by Oksana Raldugina on uabirds.org

The new birding database has been created this year for collecting pictures, geographical locations and other data of observations from Ukrainian birdwatchers. Among information on other species, it contains details of new records of Short-toed Eagles in various regions of Ukraine. The site has been made by Askar Isabekov and Andrew Simon as an analog of the well-known project for Kazakhstan that has already existed for 10 years. One more similar website is dedicated to Siberian birds. There is not any record of Short-toed Eagle on the last one yet; nevertheless, even isolated observations made at the edge of the species range would be of the great interest for ST Eagle researchers.
