The Common Yellowthroat
(Geothlypis trichas) is a bird species breeding in wetlands across much of North America (Zink and Klicka, 1990; Guzy and Ritchison, 1999).
These species include Wood Duck, Great Blue Heron, Marsh Wren (wetland species), Willow Flycatcher, Gray Catbird, Common Yellowthroat
, Yellow Warbler, and Song Sparrow (grassland and shrubby field species).
To evaluate potential differences in fitness relative to phenological period, we estimated mass change in 13 species of landbird migrants [Red-eyed Vireo (Vireo olivaceus), Ruby-crowned Kinglet (Regulus calendula), Hermit Thrush (Catharus guttatus), Veery (Catharus fuscescens), Wood Thrush (Hylocichla mustelina), Gray Catbird (Dumetella carolinensis), Blue-winged Warbler (Vermivora pinus), Nashville Warbler (Vermivara mficapilla), Magnolia Warbler (Setophaga magnolia), Chestnut-sided Warbler (Setophaga pensylvanica), Ovenbird (Seiurus aurocapillus), Common Yellowthroat
(Geothlypis trichas), and White-throated Sparrow (Zonotrichia albicollis) ].
Temporary (migrating) residents included the hermit thrush, eastern towhee, wood thrush, white-throated sparrow, ovenbird, ruby-crowned kinglet, blackpoll warbler, common yellowthroat
, and blue-throated warbler.
