While the Yellow-throated Vireo is associated with forest edge habitat, it actually requires large blocks of forest to breed successfully. Numbers decrease sharply in forests smaller than 100 hectares (250 acres) in the northeastern United States.
The Yellow-throated Vireo is typically a solitary bird on migration and during the winter. It forms only loose associations with mixed-species foraging flocks. In the summer, pairs associate only long enough to raise a brood of young.
