Eurasian collared doveStreptopelia decaocto
Smaller than common pigeons, with ash-grey plumage, a black neck band, which discontinues at the front. Neck and chest have pink tinge. The species is widespread in South Asia, Europe and North Africa. The Thracians worshiped it as a sacred bird that lived in the Balkans since ancient times.
Back in 1838, the species was first scientifically recorded in Bulgaria. Later in the 20th century it began to rapidly expand its European territory, reaching Norway and Britain. They travel singularly or in flocks near farms and settlements, but rarely outside them.
In favourable habitats the collared doves breed throughout the year. Some couples grow up to six broods a year. They build their nests in a variety of places - trees, buildings, lamp posts and more. The nest typically contains two eggs and is constructed of twigs and has a loose base, which allows seeing the eggs. The young leave the nest after 15-18 days.
