Stages of plumage maturation of the Tawny-bellied Seedeater: Evidence of delayed plumage maturation and cryptic differentiation between juveniles and females
(Cooper Ornithological Society, 2011-11)
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 ...
Female tawny-bellied seedeaters do not prefer more colorful males in choice experiments
(Springer Tokyo, 2013-09)
Plumage coloration has long been studied as a sexually selected character. The tawny-bellied seedeater, Sporophila hypoxantha, is a sexually dichromatic species, with adult males the more colorful sex and juvenile males ...
Male Red-crested Cardinal plumage coloration is associated with parental abilities and breeding performance
(Nature Publishing Group, 2019-12)
Avian plumage coloration deriving from carotenoid-based pigments is among the most honest signals of individual quality. It has been argued that females may differentially allocate resources based on mate attractiveness ...
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 ...
Plumage variability and taxonomy of the Capped Seedeater Sporophila bouvreuil (Aves: Passeriformes: Emberizidae)
(MAGNOLIA PRESS, 2011)
The species Sporophila bouvreuil comprises four subspecies: S. b. bouvreuil, S. b. pileata, S. b. saturata and S. b. crypta. The males of each subspecies differ in plumage whereas the females and juveniles are very similar ...
Court cleaning behavior of the white-bearded manakin (manacus manacus) and a test of the anti-predation hypothesis
(Wilson Ornithological Soc, 2014-03-01)
The cleaning of display courts is used by several forest lekking birds to possibly serve as an anti-predation strategy against terrestrial predators. Using a pit viper replica in the leaf litter 10-20 cm from the court ...
