Yellow-throated Warblers breed in pine forests with an open understory, bald cypress swamps, and woodlands near streams. During the winter, they use similar habitats as well as second-growth woodlands, parks, and gardens.Back to top
Yellow-throated Warblers eat insects such as beetles, caterpillars, flies, and scale insects. They creep up branches near the top of the canopy and probe into crevices, pine cones, and clusters of pine needles for insects. During the nonbreeding season, they also forage on insects attracted to agave and coconut palm flowers.Back to top
Yellow-throated Warblers nest in the canopy of mature forests. They tend to place the nest near the edges of branches or in Spanish moss dangling from the trees.
Females primarily build the nest. Many nests are in Spanish moss, where females make a cup-shaped pocket in the moss and line it with grasses, weeds, feathers, and strands of moss woven into the nest. In the absence of Spanish moss, females weave together strips of bark, grasses, and weed stems to form a cup and line it with plant down and feathers.

Yellow-throated Warblers hop up branches much like a Brown Creeper or Black-and-white Warbler. They forage more deliberately and with less fluttering than other warblers, probing crevices, pine cones, and pine needles for insects. Males establish territories with song during the breeding season and generally associate only with their mate and offspring. During the nonbreeding season, they form mixed-species flocks with Carolina Chickadees, Tufted Titmice, and other warblers.Back to top
Yellow-throated Warblers are common, and their populations increased by close to 1% per year between 1966 and 2019, according to the North American Breeding Bird Survey. Partners in Flight estimates the global breeding population at 2 million and rates them 9 out of 20 on the Continental Concern Score, indicating a species of low conservation concern. Yellow-throated Warblers appear to be expanding northward and are recovering from population losses at the northern edge of their range in southern Michigan and northern Ohio, the causes of which are unknown.Back to top
