How different reproduction of different pairs can be? Some adult Short-toed Eagles occupy the same sites from year to year. They had yet been identified in 2011 by photos taken since 2006 and according to previous and new observations. The birds had got indexes A11, B11 etc. although, in spoken communication we give them more harmonious names: for example, K11 is Barry, B11 is Ospry, and so on. Then later pictures of the individuals repeatedly got into the annual photo galleries. The natural identifying details are general plumage patterns, shapes of heads, wings, beaks and general silhouettes in flight from certain angles as well as signs of moulting. The number of the examined images should be enough to select the details and to collate them. Thus, now it is possible to compare the mean reproduction – – of pairs of individuals identified from year to year for certain, definitely without replacements of mates and without clear differences in objective conditions for breeding.

• K. PISMENNYI, 2015 – Data on breeding of Short-toed Eagle in Northern Ukraine – , XLS file with formulas – ; Replacement of the biggest 14 flight feathers – ; Some short notes on Short-toed Eagles in Northern Ukraine in 2014 // short-toed-eagle.net (En).
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/.
This 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. 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.
Gábor Papp reports that 4 eaglets were colour-ringed there this year and also ringing of 2 more was orginized by Zoltán Turny (MME/Birdlife) in Transdanubia /map/ and was done by rangers of Danube-Ipoly National Park at the following sites:
› Vértes – by Antal Klébert and István Staudinger; this is the 2nd year that the pair use this nest on an oak;
› the Budai Hills – by Bíró Sándor and Zoltán Turny; this is the 4th year in a row of breeding in this nest on a pine.
We would like to bring to your attention the 5th gallery of photos taken by Bernard Joubert at a nest of Short-toed Eagle in Haute-Loire /map/. Although the pair has eventually occupied another (last year’s) nest for the breeding, Bernard’s camera has captured scenes of the early nesting behaviour of the birds. Thanks to the researcher, we have a possibility to see unique moments of this eagles’ life once again.
One more season of Short-toed Eagles’ stay in Europe has begun recently. Observers watched the first scenes of their breeding activity. Please enjoy some pictures and photos:
At the first blush the pictures by Francesco are simple and rough, but they are accurate and for an experienced observer all the depicted scenes are easy to imagine in reality.
Bernard Joubert observed the same Short-toed Eagles at their old nest in Haute-Loire /map/ since March 10th. The pair occupied the nest also in 2009 and 2012 years. A special hide allows getting unique knowledge of the behaviour of the eagles and taking magnificent photos. According to a recent message from Bernard, the female has finally chosen another nest – one that was occupied in 2013.
My observations at breeding sites of ST Eagles in Kiev Region /map/ began on April 5th. Like in Haute-Loire the same old pair at first seems to be going to occupy the same nest, for 4th year in a row. Now we have to wait and see what will happen next.
At this time, when Short-toed Eagles are arriving to their breeding sites in northern parts of their European and Asian areal, we would like to draw your attention to the article about Short-toed Eagle from the monograph of Dr. Alexander Abuladze:
