Biology

The yellow-breasted chat is a shy, skulking species of bird, often being heard but not seen. The breeding habitats of this species are dense, brushy areas and hedgerows. The nests of these birds are bulky cups made of grasses, leaves, strips of bark, and stems of weeds, and lined with finer grasses, wiry plant stems, pine needles, and sometimes roots and hair. Nests are invariably placed in thick shrubs and often only about above the ground. They lay from three to five, creamy-white eggs with reddish-brown blotches or speckles, incubated by the female, which hatch in 11 to 12 days. Both parents tend the young, which fledge in roughly 8 to 11 days. Chats are apparently vigilant guards of their nests, as parasitism by

They are not as monogamous, though, as other warblers. In one study in central Kentucky, DNA fingerprinting revealed that 17% of 29 yellow-breasted chat nestlings were not sired by the male of the social pair and three of nine broods contained at least one extra-pair nestling.
