Setophaga petechia

Length: 5 inches Wingspan: 8 inches Seasonality: Summer / Migrant
ID Keys: Male yellow body with darker-shaded wings, reddish streaking on underparts

Yellow Warbler - Setophaga petechiaYellow Warblers are one of the most widespread and common warblers in North America. During the summer breeding season they can be found from north of the Arctic Circle, all the way southward through Mexico   The Yellow Warbler familiar to most in the United States appears as the bird to the right, and represents the migratory form. Additional forms exist in other parts of the Western Hemisphere (Caribbean, Mexico, Central America), and have much more chestnut or rufous color on the head.

Habitat: Woodlands, brush and thickets, orchards, residential areas. They are often found near water, including the brushy or otherwise vegetated margins around wetlands, lakes, ponds, and rivers.

Diet: Mostly insects.  Shows a decided preference for caterpillars.  Occasionally will eat fruits and berries. 

Behavior: Uses a variety of foraging methodologies, including observing from a perch and flying out to capture flying insects (flycatching), climbing through vegetation and gleaning insects from vegetation foliage, or hovering and gleaning insects.

Nesting: May through July. The nest is built in the fork of a small tree or bush by the female.  It is a sturdy, multi-layer cup, built primarily of grasses, strips of bark, and weed stems.  The inside is lined with softer materials such as downy plant fibers, hair, or feathers. She lays 3 to 6 eggs, and she alone incubates the eggs. The young hatch after about 12 days, with the young fledging about 10-12 days after hatching.Yellow Warblers are uniquely aware of the presence of Brown-headed Cowbird eggs in the nest. If cowbird eggs are detected, the female will often abandon all eggs in the nest, layering over the eggs and building a new nest floor on top of the old nest.

Migration: Yellow Warblers are neotropical migrants, wintering in Mexico, Central America, and South America.  Non-migratory forms and other forms also exist in Central America, Mexico, and the Caribbean.

Similar Species: Cape May Warbler, Wilson's Warbler.  Female Yellow Warbler also can be similar to an Orange-crowned Warbler.

South Dakota "Hotspot": They aren't a difficult species to find in most of the state. They are found in a variety of habitats, but riparian areas or brushy growth near water are areas that often hold Yellow Warblers. This includes many of the state parks in the eastern part of South Dakota, where riparian vegetation grows along a water feature.

Feeders: Yellow Warblers aren't typically common feeder visitors, but they will on rare occasions attend feeders for nectar (sugar water), fruit, or suet. This is most likely to occur in the spring or fall when unusually cold temperatures reduce normal insect foods to a minimum.

Conservation Status: Generally stable and widespread.  Not as susceptible to habitat loss as many other species, due to its preference for woodland edges and second-growth forest. The IUCN considers the Yellow Warbler to be a species of "Least Concern".
