Euracian Collared Dove - Couple



Hey friends i am back with my another bird click... Enjoy watching different birds with its information !! The Eurasian Collared Dove (Streptopelia decaocto) most often simply called the Collared Dove. It is a medium sized dove, distinctly smaller than the Wood Pigeon, similar in length to a Rock Pigeon but slimmer and longer-tailed, and slightly larger than the related Turtle Dove, with an average length of 32 cm (13 in) from tip of beak to tip of tail, with a wingspan of 47–55 cm (19–22 in), and a weight of 125–240 g . It is grey-buff to pinkish-grey overall, a little darker above than below, with a blue-grey under wing patch. The tail feathers are grey-buff above, and dark grey tipped white below; the outer tail feathers also tipped whitish above. It has a black half-collar edged with white on its nape from which it gets its name. The short legs are red and the bill is black. The iris is red, but from a distance the eyes appear to be black, as the pupil is relatively large and only a narrow rim of reddish-brown iris can be seen around the black pupil. The eye is surrounded by a small area of bare skin, which is either white or yellow. The two sexes are virtually indistinguishable; juveniles differ in having a poorly developed collar, and a brown iris. The Collared Dove is not migratory, but is strongly dispersive. Over the last century, it has been one of the great colonisers of the bird world. Its original range at the end of the 19th century was warm temperate and subtropical Asia from Turkey east to southern China and south through India to Sri Lanka. 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 1 km (0.62 mi) 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 14 and 18 days, with the young fledging after 15 to 19 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 wing beats and without use of gliding. Thank you for visiting my gallary :) Have a Nice day !! Deval Jayswal
