Yellow Warbler (Dendroica petechia) Science Article 3 abstract Although interspecific brood adoption has been reported in several species of birds, theprocess by which it occurs has seldom been reported. We observed a pair of Song Sparrows (Melospiza melodia) that adopted a brood of Yellow Warblers (Dendroica petechia) and, gradually, over several days, took over the […]

Cuckoldry and lack of parentage-dependent paternal care in yellow warblers:a cost-benefit approach
Yellow Warbler (Dendroica petechia) Science Article 10 abstract Theory suggests that a male strategy of reducing parental care in response to reducedparentage should evolve only under certain conditions. Expected paternity in subsequent matings ispredicted to be primary in effect, because it determines whether there is a future benefit to compensatemales for the cost of reduced […]
Autumn stopover ecology of the BlackpollWarbler (Dendroica striata) in thorn scrub forestof the Dominican Republic
White-faced Whitestart (Myioborus albifacies) Science Article 1 abstract We used mist-netting, color-banding, resighting, and behavioral observations to study the autumn stopoverecology of migrating Blackpoll Warblers (Dendroica striata) in coastal thorn scrub forest in the area of Cabo Rojo,Pedernales Province, Dominican Republic. Blackpoll Warblers were the most abundant migrant present in this habitatthroughout most of October […]
transoceanic migration of the blackpoll warbler:summary of scientific evidence and response tocriticisms by murray
White-faced Whitestart (Myioborus albifacies) Science Article 2 abstract The hypothesis that Blackpoll Warblers (Dendroica striata) make transoceanicflights in autumn from the northeastern U.S. and southeastern Canada to South Americahas been proposed or supported in more than 25 papers by many authors, using manytechniques.M urray (1989; unpubl.) has criticized this hypothesis, but cited only a few […]
Female Site Fidelity And Polygyny In The Blackpoll Warbler (Dendroica Striata)
White-faced Whitestart (Myioborus albifacies) Science Article 3 abstract From 1980 to 1982, 8-30% of male Blackpoll Warblers (Dendroics atriata) studied on Kent Island, New Brunswick, were bigamous each year (2 = 16.8%). I tested whether differences in the quality of the breeding situation can give rise to polygynous matings. Five territory parameters and two male […]
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. Michelle Mico, UFS (Delta Marsh) Annual Report, Vol. 30, 1995 Download article […]
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 […]
Demography and Ecology of Montane ForestBird Populations in the Green Mountains of Vermont
White-faced Whitestart (Myioborus albifacies) Science Article 4 abstract Bicknell’s Thrush (BITH) and Blackpoll Warbler (Dendroicastriata; BLPW) were selected as focal study species because: 1) Bicknell’s Thrush is restricted to montaneforests and Blackpoll Warbler is a near-obligate resident of this habitat in the Northeast Kent P. McFarland, Christopher C. Rimmer and James E. Goetz, Vermont Monitoring […]
An investigation of territorial behavior in theamerican redstart utilizing recorded songs
American Redstart (Setophaga ruticilla) Science Article 9 abstract The territorial behavior of the American Redstart (Setoph_a rz~ticilla) has been studied by Hickey (1940)) and in greater detail by Ficken (1962). Hickey has described this species as being ‘highly territorial,’ defending an area by song and formalized displays. Ficken has described the territory as being maintained […]
Continent-wide variation in feather colour of a migratory songbird in relation to body condition and moulting locality
American Redstart (Setophaga ruticilla) Science Article 7 abstract Understanding the causes of variation in feather colour in free-living migratory birds has been challenging owing to our inability to track individuals during the moulting period when colours are acquired. Using stable-hydrogen isotopes to estimate moulting locality, we show that the carotenoid-based yellow
