Un énorme dortoir de Faucons crécerellettes en Albanie

The Lesser Kestrel (Falco naumanni) is one of the most gregarious species of the Falco genus. Not only are they colonial breeders (up to 500 pairs), but also they usually tend to gather in flocks during the autumn migration. Large assemblies of Lesser Kestrels have been reported during migration or wintering (e.g., 6,000-10 ,000 individuals in a town in South Africa). Recent surveys by the Ligue pour la Protection des Oiseaux (LPO) revealed a roost of over 28 000 Lesser Kestrels in Senegal.
On 18 July, 2008, Piotr Miniasa, Krzysztof Kaczmarekb, Anna Piaseckac and Marika Kuncewiczd encountered a large roost of Lesser Kestrels in the Drino valley, near the village of Jorgacat (39u569N, 20u169S), southeastern Albania. During the late afternoon numerous groups of birds, comprising 10-50 individuals each, were spotted along a stretch of agricultural land measuring several kilometers. They estimated the total number of Lesser Kestrels in the valley at 4,000-6,000 individuals.
Large aggregations of Lesser Kestrels seem to be rare within the European breeding range of the species, where only birds coming from considerably more limited areas gather. If individuals from a local breeding population made up the majority at the Albanian roost, this country, in contrast to previous reports, would appear to have one of the largest European populations of Lesser Kestrel
