STE in Northern Ukraine. Video & data on breeding. 2016

Mar 26, 2017 / Comment

Short videos representing scenes of life of Short-toed Eagles in Northern Ukraine have been compiled from those that were shot in previous year. Also, you can view here a few tables containing statistical data collected in the region within 2004-2016 years and processed to a certain extent. The artificial platform for Short-toed Eagle nestingThey include: general breeding success, frequency of nesting tree change, distances between two nesting trees occupied by one pair in two consecutive seasons and between all nesting trees at the same breeding sites, nesting tree diameter, nest height, estimated nest departure dates, reproduction rate of certain pairs.

 

Meeting in Roquefixade (France), a brief review

Roquefixade: a lot of sites for Short-toed Snake EaglesParticipants of the 4th Circaetus meeting

After Langeac (2004), Nadaillac (2008), and Florac (2012) the 4th Circaetus meeting took place in Roquefixade (the Ariège Department), on October 8th and 9th, 2016. Forty naturalists involved in the monitoring of the species, found themselves there at the invitation of Nature Midi-Pyrénées and LPO Mission Rapaces, to share their experience of the studies. The total number of the meeting participants was about fifty. The program illustrated the diversity of birders’ approaches within their means and goals.

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.
