The Santa Marta wood warbler ( Myiothlypis basilica , syn .: Basileuterus basilicus ) is a small songbird from the wood warbler family (Parulidae). It is easy to identify by its distinctive head plumage and can be easily distinguished from other members of the genus Myiothlypis .
features
Santa Marta wood warbler reach a body length of 14 centimeters. The wing length is 6.3 centimeters in the male, 6.4 to 6.6 centimeters in the female. Adult Santa Marta wood warblers have a thin white crown stripe on the black crown of the head and a wide white superciliar stripe that extends to the black nape of the neck. There is a semicircular white spot under the eye, another behind the ear; the rest of the head plumage is black. The animals have an olive-green upper side plumage with olive-brown to dark brown wing-coverts, a yellow lower-side plumage and a white throat. Young birds in the first year hardly differ from adult birds except for the olive tips on the white crown stripe. The plumage on the flanks is slightly olive washed. Young birds in the moulting wear a cream to buff colored drawing instead of the white plumage-parts on the head; the rest of the head plumage is dark grayish. No other distinguishing features are known.
Occurrence
Santa Marta wood warblers are endemic to the mountain ranges of the Sierra Nevada de Santa Marta National Park in northern Colombia . They live in pairs or in small groups on the edge of bush forests, dense undergrowth in stunted forests or secondary forests , often along a body of water or in ravines , at heights of 2100 to 3000 meters. However, they are usually found above an altitude of 2300 meters. There are no studies on the breeding behavior and nest building.
Due to the small, fragmented distribution area, they have been listed as vulnerable by the IUCN since 2004. The exact population size is unknown; between 1000 and 2499 individuals are estimated. The bird protection organization BirdLife International found a decrease in the population.
