Setophaga angelae

Dendroica angelae

[edit] Identification

Upperside mostly black with white wing-bars, thin white eye-brow, broken white eye-ring, and white spots on ear-coverts and neck. Underparts are basically white with strong black stripes.

Immatures are more gray, and in even younger birds, with greenish colors replacing the black.

[edit] Distribution

Elfin-woods Warbler was not discovered until 1971. It is endemic to Puerto Rico, where it is limited to two areas: eastern Puerto Rico where it is found in Luquillo Mountains, and in the west, where it is only found in the upper parts of Maricao State Forest.

It is considered threatened due to the small area of occurrence and the limited habitat. The two areas are 100 miles apart, and there is therefore very limited chance of gene flow from one area to the other.

This is an immature bird based on the grey rather than black markings
