September 16, 2015 – Warbling Vireo (Vireo gilvus)

Requested by: mostdelightfulhat

Found throughout most of western Canada, the United States, except the southeast, and parts of Mexico and Central America, these small birds are known for their distinctive songs. Previously considered two separate species, there are now six recognized subspecies of Warbling Vireo. They eat caterpillars, moths, and other insects, along with some fruit in the fall and winter. Females do a larger share of the nest building and chick care, though males assist them and guard them during nest construction. Both parents aggressively defend the nest from jays and other nest predators, mobbing them if they get too close.
