There are two forms of the
Yellow-rumped Warbler, the Myrtle and the Audubon's. The Audubon's (shown in
the picture to the right) is generally found in the western half of the
continent, while the Myrtle is generally found in the eastern half.
Note the differing throat color and facial pattern for the two forms, as seen in
photos of both (bottom of the page). Both forms can be found in South Dakota.
Yellow-rumped Warblers are able to digest some berries and fruits that most
other warblers can't. This allows them to arrive earlier in the spring and
stay later in the fall than many other warblers, and also allows them to
winter in the southern U.S
Habitat: Conifer forests in the summer,
common in a wide variety of habitats during migration.
Diet: Insects and berries. Winters
further north than most warblers because of it's ability to digest berries.
Behavior: Uses a wide variety of methods when
foraging for food, including flycatching and snatching insects in mid-air,
hovering and grabbing prey from the foliage, clambering through foliage and
along branches and tree trunks, or feeding on the ground. Males stick
very tightly to females during courtship, exhibiting courtship displays at
Nesting: Late May through mid-July
Migration: Neotropical migrant, wintering in the southern U.S. and
Conservation Status: Generally stable throughout its range.
