Green Balkans observes pre-migratory flocks of Lesser kestrels in Thrace

Sep. 07, 2022
The most numerous pre-migration gathering of Lesser kestrels in Thrace was established by Green Balkans experts on the territory of northeastern Greece.

In August this year, representatives of the project "Life for Lesser kestrel" LIFE19 NAT/BG/001017 implemented by the Green Balkans with the support of the LIFE Program of the European Union, registered about 50 individuals in the area.

In 2021, the team observed for the first time more than 80 Lesser kestrels roosting together in the same area, and until now there have been no similar sightings for this territory.
In the wider region of Thrace, in the range of Bulgaria, Greece and Turkey, more than 22 nesting colonies of rare falcons are known, but the formation of common roosting sites during pre-migratory gatherings has so far only been reported in Greece and Bulgaria.

Thanks to the tracking of Lesser kestrels by means of satellite transmitters and field surveys from the Green Balkans, two areas of pre-migration gatherings have been established in Greece, as well as several in Bulgaria on the territory of the Protected Area "Sakar", Saint Iliyski Heights, the area of Burgas and other places. There are similar messages from experts and amateur ornithologists, such as Hristo Peshev, Petar Stankov, Yordan Vasilev, etc.

Pre-migration sites are extremely important for this bird species, where they gather additional energy reserves necessary for the long flight to wintering grounds in Africa.
