The prairie warbler (Setophaga discolor) is a small songbird of the New World warbler family.

Description

These birds have yellow underparts with dark streaks on the flanks, and olive overparts with rusty streaks on the back; they have a yellow line above the eye, a dark line through it, and a yellow spot below it.

=Vocalizations=

Prairie warblers have two categories of songs, referred to as Type A and Type B. Type A songs are typically a series of ascending buzzy notes. The B songs are an ascending series of whistled notes that often contain some buzzy notes. Compared to A songs, the B songs are lower in pitch, have fewer, longer notes. The total song length is longer as well in Type B songs. The use of these two song categories is associated with certain contexts. A songs are sung throughout the day when males first arrive on their breeding grounds. Once males are paired they begin to sing B songs during the dawn chorus and then will intersperse A songs in their singing during the rest of the day. During this later period of singing A songs are typically used near females, near the nest, and in the center of their territories. In contrast B songs are used when interacting or fighting with other males and near the borders of their territories.

Part of their call note repertoire is a tsip call. During dawn, chorus B songs are interspersed with rapid loud "check" calls.

Distribution and habitat

These birds are permanent residents in the southern parts of their range. Other birds migrate to north-eastern Mexico and islands in the Caribbean.

Behaviour and ecology

=Breeding=

Their breeding habitats are brushy areas and forest edges in eastern North America. The prairie warbler's nests are open cups, which are usually placed in a low area of a tree or shrub. Incubation period is 12 to 13 days.

=Feeding=

Prairie warblers forage actively on tree branches, and sometimes fly around with the purpose of catching insects, which are the main food source of these birds.

=Behaviour=

These birds wag their tails frequently.

Status

The numbers of these birds are declining due to habitat loss; this species also suffers from nest parasitism by the brown-headed cowbird.
