The gray wood warbler ( Setophaga plumbea , syn .: Dendroica plumbea ) is a small songbird from the genus of the wood warbler ( Setophaga ) in the family of the wood warbler (Parulidae). This species forms a superspecies with the bird species Black Warbler ( Setophaga pharetra ) and Puerto Rico Wood Warbler ( Setophaga angelae ) . The distribution area is in the Lesser Antilles . The IUCN lists the species as "not endangered" (least concern).
features
Gray warbler reach a body length of 14 centimeters. The wing length is 5.8 to 6.6 centimeters in the male and 5.6 to 6.2 centimeters in the female. Adult gray forest warblers have gray head plumage, a conspicuous white spot over the reins , a narrow, whitish, fuzzy stripe over the eyes that begins above the eye and extends to the neck and a white line under the eye. The upper side plumage is gray, the wings blackish with gray feather edges and two white wing bands. The tail is blackish with gray feather edges and white tail tips on the outer feathers, the under tail-coverts are white. The underside plumage is medium gray with a white central region on the throat, chest and abdomen. The beak is blackish and the legs are flesh-colored.
Young birds in the first year have dull olive to greyish-olive head and top plumage. The stripe above the eyes, the spot above the reins, the line under the eye and the underside plumage is pale yellow.
Occurrence, nutrition and reproduction
Gray Warbler occurs in Guadeloupe ( Marie-Galante , Terre-de-Haut ) and Dominica in the Lesser Antilles. The birds, which are loyal to their location, inhabit dry forest and bushland in lowlands, small mixed vegetation with a lot of undergrowth in the mountains and rainforests. Their diet consists of insects and berries. They look for these in the lower regions of the vegetation, mainly in the undergrowth. They can easily be observed.
The breeding season takes place between March and July. They put their bowl-shaped nest low in bushes or in bromeliads. They use leaves and fine roots as nesting material. The nest is less compact than that of the related species Strichelwald warbler. A clutch consists of two to three eggs. There are no studies on the incubation period and nestling time.
Systematics
The birds on Guadeloupe have a darker underside plumage and an indicated blurred formation of spots on the throat and in the upper chest area; especially with the plumage in the first year. They were called the subspecies Setophaga p. guadeloupensis described; this subspecies is not officially recognized.
