Yellow Warbler (Dendroica petechia) Science Article 8 abstract Across its vast range, the Yellow Warbler is a highly variable species. Forty-threesubspecies are currently recognized, and are treated geographically as three groups. The aestivagroup breeds throughout much of the U.S. and Canada, from northern Alaska, northern Yukon,northwestern and central Mackenzie, northern Saskatchewan, northern Manitoba, northernOntario, central […]

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 […]
Notes on the Yellow Warbler in Surinam.
Yellow Warbler (Dendroica petechia) Science Article 9 abstract The Yellow Warbler (Dendroica petechia) is a common winter visitor in Surinam. According to Zimmer (Amer. Mus.Novit. No. 1428, 1949: 5), only the race aestiva has been taken there, but the race brewsteri probably also occurst here since it has been found in both British and French […]
Yellow Warbler nests: building materials and cowbirdparasitism
Yellow Warbler (Dendroica petechia) Science Article 4 abstract Nests are traditionally defined as receptacles in which to house eggs and chicks; however, for the Yellow Warbler (Dendroica petechia), nests may have additional biological significance, especially with respect to Brown-headed Cowbird (Molothrus ater) parasitism.

JUVENILE GRAY JAY PREYS UPON MAGNOLIA WARBLER
Magnolia Warbler (Dendroica magnolia) Science Article 1 abstract A juvenile Gray Jay (Perisoreus canadensis) was observed to capture, kill, and eata healthy juvenile Magnolia Warbler (Dendroica magnolia), demonstrating that Gray Jaysdepredate free-flying birds in addition to nestlings and dead adults. Predation of birds, which was manifested in a recently independent bird, may be a regular […]
SERIES OF NESTS OF THE MAGNOLIA WARBLER.
Magnolia Warbler (Dendroica magnolia) Science Article 2 abstract The warblers were late in 1907. The cold, backward spring was behind time in unfolding catkin and leaf whereon the insect hosts prey, and the warblers who live on the insect life keep pace with the resurrection and birth of moth and butterfly, mosquito and aphis, caterpillar […]
Interspecific song learning in a wild Chestnut-sided Warbler.
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. […]
DEMOGRAPHIC AND POPULATION RESPONSES OF CAPE MAYWARBLERS WINTERING IN MULTIPLE HABITATS
Cape May Warbler (Dendroica tigrina) Science Article 2 abstract Wintering Cape May Warblers (Dendroica tigrina) were studied in three habitats along an altitudinal gradient in the Dominican Republic. Results of this study are some of the first to link both population responses and individual condition of nonbreeding birds to prevailing ecological conditions across divergent habitats. […]
The Cape May Warbler (Dendroica tigrina) as an Abundant Autumnal Migrant and as a Destructive Grape Juice Consumer at Berwyn, Pa.
Cape May Warbler (Dendroica tigrina) Science Article 1 abstract For several years, previous to the crushing sleet of the past winter, a pie cherry tree crowned with the foliage of a fugitive Clinton grapevine overhung my shop platform; and a thirty foot pine bending under the weight of several Niagara grapevine runners, stood close to […]
