Chestnut-sided Warbler (Dendroica pensylvanica) Science Article 2 abstract Vocal learning involving imitation is the prevalent mode of song development in songbirds. The evidence for vocal learning both from experimental studies and from local song variants shared among neighbors (dialects) indicates that songbirds generally learn from their own species, and that a genetically determined signal recognition […]

EXTRAPAIR PATERNITY INCREASES VARIABILITY INMALE REPRODUCTIVE SUCCESS IN THE CHESTNUT-SIDEDWARBLER (DENDROICA PENSYLVANICA), A SOCIALLYMONOGAMOUS SONGBIRD
Chestnut-sided Warbler (Dendroica pensylvanica) Science Article 1 abstract A monogamous mating system that includes extrapair fertilization can potentially generate higher variability in male reproductive success than monogamy without extrapair fertilization. That increased variability could provide a correspondingly higher opportunity for sexual selection and, thus, for the origin and persistence of sexual dimorphism in monogamous species. […]
