- 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.
Breeds in a variety of edge habitats in mature deciduous and mixed deciduous forests.
Arthropods, some fruits and seeds.

- Egg Description
- Creamy white with sparse dark spots around larger end.

Nest an open cup suspended by rim from fork of small branch in tree. Made of bark strips, dry grasses, rootlets, long pine needles, leaves, or hair, held together with insect silk and spider webbing.
Forages in middle and uppers stories of forest, gleaning insects off trunks, branches and leaves. Moves slowly from place to place and searches for a relatively long time from one spot.
Though Yellow-throated Vireo has disappeared from some small forest areas, populations increased slightly between 1966 and 2014, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 3.5 million with 99% spending some part of the year in the U.S., 1% breeding in Canada, and 22% wintering in Mexico. This U.S.-Canada Stewardship species rates a 9 out of 20 on the Continental Concern Score, and are not on the 2014 State of the Birds Watch List.
