Yellow Warbler

Setophaga petechia

Early Spring Date: April 18
Late Spring Date: June 1
Most Frequently Seen: April 28 - May 8

Yellow Warblers are common in the Washington metro area, but not at Monticello Park. They nest in deciduous habitats near water, including in Alexandria along Four Mile Run and on the Haul Road at Dyke Marsh. Since 2005, the average number of spring sightings at Monticello has been about 10. They are most likely to be in the park around the first week in May.

Where to See Them in the Park

Yellow Warblers sometimes forage in the brush on the knoll. On occasion, they will go into the stream to bathe or drink, but you are more likely to see them hopping around in the brush near the stream.

Females are like the males, but they are somewhat duller and lack the red streaks. Both males and females have yellow undertail coverts.


The Yellow Warbler's song is a perky sweet-sweet-sweet-a-little-more-sweet.

The Yellow Warbler is the most widespread of all the New World warbler species. It has at least 35 subspecies, varying in size and appearance. Members of the subspecies who visits Monticello winter in Central and South America. The males of some of the other subspecies have chestnut caps.

Origin of Names

Common Names: Yellow from the plumage. The New World Warblers were named for their similar appearance to European warblers, to whom they are not related. Most of the New World warblers do not warble (sing continuously with notes that change frequently).
Genus Name: Setophaga means "moth eating".
Species Name: Petechia in the medical field refers to red spots on human skin created by broken capillaries below the surface. The red streaks on the breast of the male Yellow Warbler resemble this skin condition.
