|Brightly colored but easily overlooked. A bird of shrubland and old fields, the Blue-winged Warbler expanded its breeding grounds northward throughout the 20th century.Hybridizes extensively with Golden-winged Warbler, giving rise to the distinctly plumaged "Brewster's" and "Lawrence's" warblers.|
The Blue-winged Warbler continues to expand its range and may be responsible for the decrease in Golden-winged Warbler populations in some areas.
The oldest recorded Blue-winged Warbler was a male, and at least 9 years old, when it was recaptured and rereleased during banding operations in New Jersey.
