The brown- capped wood warbler ( Myioborus brunniceps ) is a small songbird from the genus Myioborus in the wood warbler family (Parulidae). The distribution area is in the Andes of Bolivia and Argentina . The IUCN lists the species as "not endangered" (least concern).
features
Brown-cap warblers reach a body length of 13 centimeters. The wing length is in the males 6.1 to 6.6 centimeters; in the females 5.9 to 6.0 centimeters. In the adult animals and young birds from the first year the head plumage is gray with a reddish-brown crown spot and the forehead and reins are blackish-gray.
The white line over the reins and the interrupted white eye ring are striking. The upper side plumage is gray with clearly contrasting olive spots on the coat. The back and torso are tinted olive, but grayer than the coat. The wings are blackish with narrow gray feather edges. The underside plumage is yellow. The tail is blackish with white outer feathers. The under tail-coverts are white, the beak and legs blackish.
Occurrence, nutrition and reproduction
Brown-cap warblers inhabit the edges of forests, mountain forests and clearings at altitudes of 1400 to 3200 meters. In Argentina they are mostly found at altitudes of 1400 to 1700 meters. In the department of Cochabamba in Bolivia they sometimes occur at an altitude of 3800 meters and move in the south of Bolivia outside the breeding season up to a height of 400 meters.
They seek their food consisting of insects in the lower and middle regions of the vegetation, mostly at heights of 2 to 8 meters. On their forays they can usually be seen in pairs or in small groups - often with other bird species. But they can also occur as solitary animals.
There are no studies on the nest building and the breeding and nestling times. Young birds that had just fledged were seen in January and February in the Tarija department in Bolivia.
Systematics
The tepui wood warbler ( Myioborus castaneocapillus ) used to be combined with the brown-cap wood warbler to one species. Due to the disjoint distribution and different vocal sounds, the Tepui wood warbler was recorded as an independent species, although both species are undoubtedly closely related and possibly sister species .
