Nashville Warbler

The Nashville Warbler (Leiothlypis ruficapilla) is a small songbird with a length of approximately 4.3 to 4.7 inches (11-12 cm) and a wingspan of 6.7 inches (17 cm). It weighs between 0.23 and 0.34 ounces (6.5-9.5 grams). The male and female Nashville Warblers have similar plumage, with an olive-green back, yellow underparts, and a distinctive white eye ring. The crown of the head is a rusty-red color, giving this species its common name.

During migration, the Nashville Warbler travels from its breeding grounds in Canada and the northern United States to its wintering grounds in Central America and northern South America. This species breeds in coniferous and mixed forests, particularly in the boreal forests of Canada.

The Nashville Warbler feeds primarily on insects, such as caterpillars, beetles, and spiders, which it gleans from the foliage of trees and shrubs. During migration, it may also consume fruit and nectar.

In terms of conservation status, the Nashville Warbler is listed as a species of least concern by the International Union for Conservation of Nature (IUCN). However, like many songbirds, it is vulnerable to habitat loss and fragmentation caused by deforestation and urbanization.

Birdwatchers often identify the Nashville Warbler by its distinctive white eye ring and rusty-red crown. Its olive-green back and yellow underparts make it difficult to spot among foliage, but its distinct markings make it easier to identify. During migration, these birds may be seen in a variety of habitats, including woodlands, forests, and even urban parks and gardens.
