Circaetus gallicus information navigator

This video footage is made up of short parts shot in Northern Ukraine within 2017-2019 years during field observations at Short-toed Eagles’ breeding and hunting areas. The attention was aimed rather at various kinds of behaviour, including territorial conflicts, training of juveniles, individual behavioural features of particular birds.

The 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.

This 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.

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. They 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.

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.net – ; in the form of XLS file with formulas: (En).

Average 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.
