The Black-throated Blue Warbler is a small, compact songbird, with a length of approximately 4.3 to 5.1 inches and a wingspan ranging from 7.1 to 7.9 inches. The bird's overall shape is characterized by a short, rounded body, a short tail, and relatively long wings. Its bill is thin and sharp, perfect for capturing insects in mid-air or gleaning them from foliage. The bird's legs and feet are relatively small and delicate, which allow for agile movements through its preferred woodland habitat.

The Black-throated Blue Warbler exhibits a striking sexual dimorphism in its plumage, with males and females exhibiting dramatically different color patterns. Males are easily recognizable by their deep blue upperparts, black throat and flanks, and a distinct white patch on the lower belly and under the tail. The wings also feature a prominent white patch, which is visible in flight or when perched. Females, on the other hand, have olive-green upperparts, a buffy or whitish throat, and a pale yellow wash on the breast and belly. Both sexes have dark eyes and black legs and feet.

Black-throated Blue Warblers are energetic and active birds that spend much of their time foraging for insects and arthropods in the understory and middle levels of forests. They are known to use a combination of gleaning, hover-gleaning, and flycatching techniques to capture their prey. During the breeding season, males can be heard singing their distinctive, buzzy songs, which are used to establish and defend territories and attract potential mates. Black-throated Blue Warblers are also migratory birds, breeding in eastern North America and wintering in the Caribbean and Central America.

The preferred breeding habitat of the Black-throated Blue Warbler is mature deciduous and mixed forests, particularly those with a dense understory of shrubs and small trees. They are often found in areas with a mix of large, older trees and younger saplings, as well as in forests with a rich herbaceous layer. During migration and in their wintering grounds, Black-throated Blue Warblers can be found in a wider range of habitats, including secondary forests, woodland edges, and scrubby habitats. They are typically found at elevations ranging from sea level up to 3,500 feet.

The Black-throated Blue Warbler plays an essential role in maintaining the health and balance of forest ecosystems. As insectivores, they help control insect populations and maintain biodiversity within their habitats. Their predation on insects can also benefit human interests, as they help to keep pest populations in check and reduce the need for chemical pest control. Additionally, these birds are important indicators of overall forest health, as their presence often signifies the existence of a diverse and thriving ecosystem. Lastly, their striking appearance and melodic songs make them a popular attraction for birdwatchers and nature enthusiasts, contributing to ecotourism and fostering an appreciation for nature.
