Generally a lot bigger than whitewings and much slower flyers than either mourning or whitewing. Shot one bird that I put into my mourning dove pile and when I started to clean the birds I noticed a faint collar and odd wing color. It appears that there is some interbreeding going on.
BTW,they are larger than a white wing
The Eurasian dove and the white wing dove we have shot for years here in Utah and in Arizona both are generally the same size. The adult white wing is often larger.
The Eurasian dove has longer tail feathers. For body size here and in Arizona, both are the same, if both are adult birds and not half breeds.
White-winged Doves are large, plump doves at 29 cm (11 in). Most populations of White-winged Doves are migratory, wintering in Mexico and Central America.
Eurasian 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. Juveniles differ in having a poorly developed collar, and a brown iris.
The collared dove is not wary and often feeds very close to human habitation and often 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 sizeable 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.
