New World Warblers (Parulidae)

Tepui Whitestart (Myioborus castaneocapilla) - HBW 15, p. 781

French: Paruline des tépuis German: Tepuiwaldsänger Spanish: Candelita de Tepuí
Other common names: Tepui Redstart

Taxonomy: Setophaga castaneocapilla Cabanis, 1848, Roraima, 7000 feet [c. 2130 m], Venezuela.
Forms a superspecies with M. cardonai and M. albifacies, and M. pariae presumably also part of same group. Formerly considered conspecific with M. brunniceps, but the two differ in their songs and are widely separated geographically; treatment as separate species supported by recent phylogenetic study, which suggested that close plumage similarities between the two may be due to retention of ancestral traits, rather than to genetic similarity. Three subspecies recognized.
