Beginning of ST Eagle season in Europe

Apr 11, 2014 / Comment

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:

Breeding and survey season 2014 started with a rainy day in Maremma, Central Italy /map/. In spite of the bad weather, the pair was doing its job and this is my 38th year with the Short-toed Eagles.

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.

 

Some results of Short-toed Eagle monitoring in Ukraine

Nov 29, 2013 / Comment

Monitoring of 9 different pairs of Short-toed Eagles has been conducted during 10 years in Northern Ukraine (Kiev Region /map/, Mizhrichynskyi Park /map/ of Chernihiv Region, southern part of Sumy Polissya /map/). Some calculations and results of the monitoring are represented in tabular forms:

K. PISMENNYI, 2013 – Some data on breeding of Short-toed Eagle in Northern Ukraine // short-toed-eagle.netShort-toed Eagle. file; in the form of XLS file with formulas: Short-toed Eagle. file (En).

Juvenile Short-toed Eagles have recently left their nests. Typical (left) and untypical (right) behaviour in the presence of humanAverage breeding success amounts to 0.60 juvenile / territorial pair and is quite close to this index for France: 0.57. The last result is based on observations of 2835 (!) breeding cases which have been managed to make by French national Circaetus gallicus network for 11 years (Bernard Joubert, personal communication). Also some other conclusions can be made: old pines (Pinus sylvestris) are prefered by Short-toed Eagles for nesting in Northern Ukraine; the eagles more often change their nests than they successfully breed; nest height is highly variable; the eagles’ choice of a nest depends on their previous breeding success; after an unsuccessful season the nest is changed with high probability, after successful one the following choice of a nest is unpredictable.

 

Moulting of the biggest flight feathers of ST Eagles

Oct 31, 2013 / Comment

Recognizing the same Short-toed Eagle male (K11) from shorter and longer (0.8-0.9 km) distances based on condition of 14 the biggest flight feathers During 10 years of observations in Central Northern Ukraine (Kiev Region /map/, Mizhrichynskyi Park /map/) a lot of photos of several the same Short-toed Eagles have been taken. Some of them can be viewed in the galleries (just an example). Since Short-toed Eaglers’ the biggest flight feathers are often seen from a great distance they are easily recognizable in photos. Especially it concerns 4th-10th primaries of both wings. Accumulation of data allowed to determine inter-moulting periods of certain feathers:

K. PISMENNYI, 2013 – Short-toed Eagle. Replacement of the biggest 14 flight feathers // short-toed-eagle.netShort-toed Eagle. file (En).

First of all, the results might be of interest as additional information for recognizing individuals in the nature from year to year, together with individually typical plumage colouration and silhouettes in flight at certain angles in certain poses. Regular photographing of Short-toed Eagles at their breeding sites and foraging grounds allows to distinguish them with high probability without special marking, without stressing and often even without disturbing the birds at all.

 

Just some pictures from Northern Ukraine

PISMENNYI K. 2013. Northern Ukraine

This gallery contains some photos of Short-toed Eagle taken in Northern Ukraine this year. As usual, it is planned to be updated with new pictures if I manage to take something interesting. They may be not as of high quality as of interest for Short-toed Eagle watchers. That is why all of them are commented in detail. Single eagles are named individually with alphanumeric code, for example: “A11” means bird “A” of the gallery of 2011, but “A” without a number here means that the individual has not been marked yet in previous galleries.

PISMENNYI K. 2012. Northern Ukraine

Just like last year I would like to share some photos, which, though have not perfect quality, can tell something about different aspects of Short-toed Eagles’ life as here, in Northern Ukraine, so in general. Also like last year the photo gallery will be updated with new images during the season. Every update will be described in comments.

Short-toed Eagles in Ukraine in 2011
Although some photos taken by me this year in Ukraine aren’t of the highest quality, they’re interesting (at least in my opinion) and they can’t wait for the autumn to be put on the site. That is why the regular annual gallery is published right now in a bit different format. It is going to be renewed during the season of observations of Short-toed Eagles.
