Life of Short-toed Eagles in photos by Bernard Joubert

Feb 19, 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 Northern Ukraine. Photos of 2016

Jan 31, 2017 / Comment

PISMENNYI K. 2016. Northern UkraineHere is the next annual gallery of pictures taken in Kiev, Chernihiv and Sumy Regions of Northern Ukraine in 2016. Short-toed Eagles of local pairs monitored during more than 10 years are captured in them. All the birds are indicated in captions by a letter and a year of the first representation in photo galleries on our site, starting with A11 – the old, very striped and dark-spotted, rather small but aggressive female living in the Mizhrichynskyi Nature Park /map/.

 

Age-related timing of Short-toed Eagle migration

Many thanks to Luca Baghino for sharing this fresh article dedicated to ongoing studies of Short-toed Eagle migration from regions of Europe:

White Short-toed Eagle fledgling in Spain in 2013

Nov 22, 2015 / 1 Comment

EL ÁGUILA BLANCA (Circaetus gallicus)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.

 

Findings of the eagles in the Chernihiv Polissya

Sep 27, 2014 / Comment

The northern part of Chernihiv Region, so-called the Chernihiv Polissya /map/, is one of the best regions of Ukraine for Short-toed Eagles’ habitation. These lands, rich in Grass Snakes, Vipers, other reptiles and also in old pine forests, provide the eagles with good conditions for foraging and nesting. An expert in Ukrainian birds of prey, Sergey Domashevsky, during the expedition in 2009 has recorded several probable territorial pairs of the eagles there. Some of them were observed between the Sozh, the Dnieper rivers and Zamglay Bog /map/.

SKEETER A, SIMON A, MOROZ V, PISMENNYI K. 2011-2014. Chernihiv PolissyaThis year a local birdwatcher, Artem Skeeter, has found Short-toed Eagles’ nest at a place where he saw them during a few years before. Artem has discovered the nest just after finding of one old tail feather under a perch at the breeding site.30.08.14 : an adult male Short-toed Eagle gives a snake to the juvenile not far from the nesting tree He has managed to take a video of feeding the juvenile eagle by its father on a pine within the site. Also photos of the birds have been taken there in 2011-2012 and this year by Artem and by Andrew Simon, Viktor Moroz and me. This year’s juvenile could already fly on August 9. The date is the earliest known in Northern Ukraine for the last 10 years. On September 9 another juvenile Short-toed Eagle, judging by all, an offspring of the neighbour pair, was observed in the hovering flight over typical hunting grounds far from forests, that is unusually early for this region too.
