Yellow Rumped Warbler, Dendroica coronata

Facts and Information

Yellow Rumped Warbler migration through the San Juan Islands Washington. The Yellow Rumped Warbler is part of the order Passerine, also known as Perching birds or songbirds, and are among the most common birds on earth. Travelling in large flocks, they build nests in trees and hunt insects from the tree canopy during the spring and summer months. In the winter and colder months they forage for available berries.

The Yellow Rumped Warbler is a frequent sight here in Washington state, with a widespread, stable population. They are commonly found all across the state and across the country, as well as into Canada. They are a migratory species, spending winters in the southern states and Mexico, and summers in the western United States and all across the Canadian provinces. These birds are generally among the first breeders to return north in the springtime. This bird is one of only seven species of warblers that are commonly found in the San Juan Islands. They arrive in mid-to-late March and some remain into September before beginning their journey south."

Yellow Rumped Warblers have distinctive yellow patches on their rumps, as their name indicates. There are actually two subspecies of this bird, the Audubon and the Myrtle, which have certain color variations that distinguish one from the other. The clearest variation between the two is the bright yellow throat patch of the Audubon subspecies, whereas the Myrtle's throat patch is white, as well as being slightly larger. Both subspecies are just under five inches long with thin, pointed bills, a long narrow tail, two white wing bars, and a broken light ring pattern around the eyes.
