Yellow Warbler (Dendroica petechia) Science Article 13 abstract Using morphological or behavioural features correlated with paternal care, females can, priorto mating, assess the potential parental contribution of males. As a first step in a study of female matechoice in yellow warblers, this study was designed to examine the importance of paternal care by malesof diVering […]

Yellow Warbler (Dendroica petechia) Science Article 15 abstract We studied Wilson’s Warbler (Wilsonia pusilla) and Yellow Warbler (Dendroica petechia) habitat use in allopatric and sympatric populations in the Rocky Mountains of northern Colorado and southeastern Wyoming in order to better understand the different habitat needs and interactions of these two species. Janet M. Ruth and […]

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 […]

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 […]

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 (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 […]

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 […]

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 […]

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 […]

American Redstart (Setophaga ruticilla) Science Article 4 abstract We examined American redstarts (Setophaga ruticilla) for protozoan blood parasites on their wintering grounds to determine whether transmission of these parasites occurs prior to spring migration. A total of 73 blood smears from 37 birds were examined for presence and intensity of infection. Thirty-six birds were sampled […]
