In some sexually dichromatic passerines, juvenile males retain a plumage similar to that of adult females through their first year or longer (delayed plumage maturation). The Tawny-bellied Seedeater (Sporophila hypoxantha) ...
A spectrophotometric study of plumage color in the Eared Dove (Zenaida auriculata), the most abundant South American Columbiforme
(Public Library of Science, 2016-05)
For birds, plumage color perception is critical in social interactions such as courtship, in both monochromatic and dichromatic species. In the Eared Dove (Zenaida auriculata), perhaps the most abundant South American ...
