Food abundance and parental care in yellow warblers

Yellow Warbler (Dendroica petechia) Science Article 1 abstract Emlen and Oring (1977) suggested that monogamy in birds is maintained because of the need for strict biparental care. A corollary of their suggestion is that paternal care should decrease under conditions of high food abundance. An alternative is that paternal care would increase if males take […]

Extra-pair mating, male plumage coloration andsexual selection in yellow warblers (Dendroica petechia)

Yellow Warbler (Dendroica petechia) Science Article 14 abstract Extra-pair mating has been proposed as a source of sexual selection responsible for secondary sexual traitsthat are common among socially monogamous birds, although supporting evidence is scant. In the socially monogamous yellow warbler, males are larger than females, and unlike females, have extensivereddish streaking on their breasts. […]

Yellow-billed Cuckoo (Coccyzus americanus): A Technical Conservation Assessment

Yellow-billed Cuckoo (Coccyzus americanus) Science Article 5 abstract In western North America, yellow-billed cuckoos (Coccyzus americanus) have undergone catastrophic declines; the eastern subspecies has undergone less rapid declines in most areas since approximately 1980. Direct loss and degradation of low-elevation riparian woodland habitats have been cited as the primary causes for the declines in yellow-billed […]

Interspecific Aggression By Yellow Warblers In A Sun Coffee Plantation

Yellow Warbler (Dendroica petechia) Science Article 5 abstract Non-breeding habitat use is mediated infrequently by interspecific aggression in migratory birds. Such aggression occurs most commonly among birds exploiting rich resource patches such as nectar, fruit, or other similar resources (Greenberg et al. 1994). Interspecificterritoriality and dominance is less commonly noted among insectivorous species (Rappole and […]
