Blue-winged Warbler

Blue-winged Warbler: Medium-sized warbler with olive-green upperparts and yellow underparts. The head is yellow with thin black eye line and olive-green nape. Wings are dark gray with two white bars. When its range overlaps with the Golden-winged Warrbler, it often interbreeds with or displaces it.

● Song: "beee-buzzz"

● Foraging & Feeding: Blue-winged Warbler: Diet consists of insects and spiders; forages in trees and shrubs.

● Breeding & nesting: Blue-winged Warbler: Four to seven brown and gray flecked white eggs are laid in a grass-lined cup of dead leaves and fibers, and built on or very near the ground in thick undergrowth. Incubation ranges from 10 to 12 days and is carried out by the female.

● Similar species: Blue-winged Warbler: Occasionally hybridizes with Golden-winged Warbler to produce offspring with characteristics of both parents. Some have mostly white underparts (Brewster's Warbler), while some have the yellow plumage of the Blue-winged, but the dark throat of the Golden-winged (Lawrence's Warbler).

Flight Pattern

Weak fluttering flights of short duration.

● Range & Habitat: Blue-winged Warbler: Breeds from Nebraska, central Iowa, southern Wisconsin, southern Ontario, and central New England south through east-central and Atlantic coast states to northern Georgia. Spends winters in the tropics. Preferred habitats include abandoned fields and pastures grown up to saplings; forest clearings and edges with clumps of catbrier, blackberry, and various bushes and young trees.

4 and 6 letter alpha codes

The four letter common name alpha code is is derived from the first two letters of the common first name and the first two letters of common last name. The six letter species name alpha code is derived from the first three letters of the scientific name (genus) and the first three letters of the scientific name (species). See (1) below for the rules used to create the codes..

Four-letter (for English common names) and six-letter (for scientific names) species alpha codes were developed by Pyle and DeSante (2003, North American Bird-Bander 28:64-79) to reflect A.O.U. taxonomy and nomenclature (A.O.U. 1998) as modified by Supplements 42 (Auk 117:847-858, 2000) and 43 (Auk 119:897-906, 2002). The list has been updated by Pyle and DeSante to reflect changes reported by the A.O.U from 2003 through 2006.
