Breeding males are stunning bright yellow with a black back and red head. Females and immature males are duller, sometimes mostly grayish with just faint yellow on the face and undertail coverts. Always note two white wingbars and pale bill. Breeds mainly in coniferous or mixed forests at middle or high elevations. Winters as far south as Central America, where it can be found in any forested habitat. Often stays high in the canopy. Listen for male’s burry song in the spring and summer and short, rising rattle year-round.
