Black-Whiskered Vireo
Vireo altiloquus
The Black-Whiskered Vireo is a summer songbird of South Florida and the Keys, recognized by a bold dark line beside its pale throat.
This Caribbean species reaches Florida in spring to breed in mangroves, tropical hardwood hammocks, and mature coastal vegetation. Its repeated whistled phrases are often heard before the bird is seen.
It searches leaves and twigs methodically for insects and also eats small fruit. Dense native tree cover supports nesting and migration.
