Short-toeds in Northern Ukraine. Photos of 2018-2019

Aug 31, 2019 / 1 Comment

PISMENNYI K. 2018-2019. Northern UkraineThe photo collection of the previous year has been continued in 2019. All individuals have their unique index like K11m, where the last letter means sex: m – male, f – female, if it is known for certain. This is the continuation of a story in pictures of permanent annual monitoring of Short-toeds in Northern Ukraine which has been made for more than 15 years.

Short-toed Eagle nesting in the Visegrád MountainsThis video footage was taken by Vince Schwartz. It presents the Short-toed Eagle pair nesting in the Visegrád Hills /map/ as well as the hunting of the male of an immature pair settled in the neighbouring Pilis Hills /map/ in 2018.

Please, read the more detailed explanation by the author:

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, mean nest departure dates, reproduction rate of certain pairs.

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.
