Hawaiian Islands (based on Pratt 1979; Berger 1981; James and Olson 1991): (1) Corvus hawaiiensis (Corvidae, one species), (2) Myadestes thrushes (Turdinae, five species [two sympatric]), (3) Acrocephalus familiaris (Acrocephalinae, one species), (4) Chasiempsis sandwichensis (Monarchini, one species), (5) Hawaiian Oo and Kioea (Meliphagidae, five species [two sympatric]), and (6) Hawaiian hone...

—The Yellow Warbler (Dendroica petechia) has a mating system characterized by monogamy and biparental care, and has the broadest breeding distribution of any Dendroica species. When faced with a short breeding season and unpredictable conditions at high latitude, they display physiological responses to help optimize the tradeoff between individual risk and reproductive success. Because these ci...

Brood parasitism by Brown-headed Cowbirds (Molothrus ater (Boddaert, 1783)) often reduces the reproductive success of their hosts. We examined whether the ability of females to avoid or mitigate the costs of brood parasitism improved with age in a population of YellowWarblers (Setophaga petechia (L., 1766)) breeding near Revelstoke, British Columbia, between 2004 and 2011. Cowbirds parasitized ...

We use stable isotope data to investigate the role of winter habitat use in altering the breeding phenology of yellow warblers Setophaga petechia . We fi rst confi rm that δ 13 C and δ 15 N isotopic signatures vary with winter habitat use in this species . We then examine the relationship between winter habitat use, breeding phenology and productivity within four age-sexclasses, since life hist...

Referential alarm calls that denote specific types of dangers are common across diverse vertebrate lineages. Different can indicate a variety threats, which often require actions to evade. Thus, benefit from the call, listeners referential must be able decode signaled threat and respond it in an appropriate manner. Yellow warblers ( Setophaga petechia ) produce “seet” signal conspecifics presen...
