Family New World Warblers (Parulidae)

Least Concern

White-bellied Warbler (Basileuterus hypoleucus)


French: Paruline à ventre blanc German: Weißbauch-Waldsänger Spanish: Reinita ventriblanca

Basileuterus hypoleucus


, 1850,



Clearly very closely related to B. culicivorus, occasionally hybridizing with latter in area of range overlap in S Brazil & NE Paraguay; one recent genetic study suggested that hypoleucus is either an incipient species in the process of differentiation, or it represents a restricted polymorphism of B. culicivorus#R (but see under that species). Monotypic.


S Brazil (S Mato Grosso E to S Tocantins#R, W Minas Gerais and E São Paulo), SE Bolivia (Santa Cruz)#R and NE Paraguay.
