Hooded Warbler (Wilsonia citrina) Science Article 6 abstract We tested whether Hooded Warblers (Wilsonia citrina) experienced a smaller food supply insmall versus large forest fragments in northwestern Pennsylvania. Using 16 fragments that ranged in size from 0.7 to 214 ha, we videotaped parental feeding rates to nestlings in 35 nests and sampled arthropod abundance on […]

Hooded Warbler (Wilsonia citrina) Science Article 2 abstract Studies on the effects of forest fragmentation on the reproductive ecology of forest songbirds have focused almostexclusively on the egg and nestling stages. Little is known about survival or habitat use of fledglings in their first weeks out of the nest.Weradiotracked adult HoodedWarblers (Wilsonia citrina) attending fledglings […]

Hooded Warbler (Wilsonia citrina) Science Article 5 abstract Males of socially monogamous species may benefit from using behavioral tactics to ensure their paternity of the young produced by their social mates. We tested whether male Hooded Warblers (Wilsonia citrina) use mate guarding and high song output in an attempt to prevent extra-pair copulations (EPC) by […]

Hooded Warbler (Wilsonia citrina) Science Article 4 abstract Adoption is a widespread phenomenon in birds and generally occurs at a low frequency within a species (reviewed in Rohwer 1986, Meek and Robertson 1991). Adoption of fledglings is common in seabirds due to the mobility of chicks soon after hatch. BRIDGET J .STUTCHBURY, The Auk 113(1):218-220, […]

Hooded Warbler (Wilsonia citrina) Science Article 3 abstract Overwintering male and female Wilsonia citrina defended exclusive feeding territories in the Yucatan Peninsula, Mexico. Woody vegetation ranging from successional scrub to tall evergreen forest was utilized by the species, but males were most abundant in closed-canopy forest of moderate to tall stature, while females were commonest […]

Hooded Warbler (Wilsonia citrina) Science Article 1 abstract Modelling and mapping of hooded warbler (Wilsonia citrina) nesting habitat in forests of southern Ontario were conducted using Ikonos and Landsat data. The study began with an analysis of skyward hemispherical photography to determine canopy characteristics associated with nest sites. It showed that nest sites had significantly […]

Hooded Warbler (Wilsonia citrina) Science Article 7 abstract Dwight (1900:284-285) provided two hypotheses to explain the variable amount of black plumage in female Hooded Warblers (Wilsonia citrina): ‘The adult winter plumage . . . shows a variable amount of black about the head and throat.
