Mourning Dove (Zenaida macroura)

About the Bird

Seen/Heard at
Decorah, Decorah North

Diet
Mourning doves are ground foragers. They eat primarily seeds, but will also eat berries and snails. Nestlings are fed crop milk or “pigeon milk” by both parents: a secretion from the lining of the crop of parent birds that is regurgitated to young birds.

Nesting
Mourning Doves breed from mid-March through mid-August. Males bring nesting materials to females, including pine needles, twigs, and grass stems. Females weave them into loose, unlined, cup-shaped nests about eight inches across. Mourning doves lay two white unmarked eggs per clutch and may produce as many as six broods per year in the southern United States. Females and males incubate eggs for 14 days and young stay in the nest for 12-15 days before fledging. Both sexes feed young. To learn more, visit Cornell’s website

Doves, Flamingos, and male Emperor Penguins are the only three bird species that produce ‘milk’ to feed their young. This curd-like substance contains protein, fat, minerals and antibodies to nourish and protect young.
