Eurasian Collared Dove - Behaviour

Behaviour

Collared Doves typically breed close to human habitation wherever food resources are abundant and there are trees for nesting; almost all nests are within a kilometre of inhabited buildings. The female lays two white eggs in a stick nest, which she incubates during the night and which the male incubates during the day. Incubation lasts between fourteen and eighteen days, with the young fledging after fifteen to nineteen days. Breeding occurs throughout the year when abundant food is available, though only rarely in winter in areas with cold winters such as northeastern Europe. Three to four broods per year is common, although up to six broods in a year has been recorded.

The male's mating display is a ritual flight, which, as many other pigeons, consists of a rapid, near-vertical climb to height followed by a long glide downward in a circle, with the wings held below the body in an inverted "V" shape. At all other times, flight is typically direct using fast and clipped wingbeats and without use of gliding.

The Collared Dove is not wary and often feeds very close to human habitation, including visiting bird tables; the largest populations are typically found around farms where spilt grain is frequent around grain stores or where livestock are fed. It is a gregarious species and sizable winter flocks will form where there are food supplies such as grain (its main food) as well as seeds, shoots and insects. Flocks most commonly number between ten and fifty, but flocks of up to ten thousand have been recorded.

The song is a coo-COO-coo, repeated many times. It is phonetically similar to the Greek decaocto ("eighteen"), to which the bird owes its zoological name. It also makes a harsh loud screeching call lasting about two seconds, particularly in flight just before landing. A rough way to describe the screeching sound is a hah-hah.

Collared Doves cooing in early spring are sometimes mistakenly reported as the calls of early-arriving Cuckoos and, as such, a mistaken sign of spring's return.

They are almost always seen in pairs and, like many birds, remain loyal to their mates.
