Breeding occurs from early April to mid-August occasionally later, based on egg dates from April 6 to September In Texas Yellow-breasted Chats chat from near sea level to m ft in a texas of brushy habitats. Eckerle and Thompson The breeding range of the eastern subspecies extends east and north from Texas and Oklahoma to the Atlantic coast, southern Missouri and the Ohio River valley but excluding peninsular Florida.
Breeding records also seem more scattered in the Post Oak Savannah and Blackland and Rolling prairies than on the map of historical records, suggesting the range of Yellow- breasted Chat in Texas has shrunk since observations were first made.
In comparison with the map in OberholserTBBA atlasers found almost no breeding evidence for extreme south Texas or near the south and central coast. Data from Breeding Bird Survey routes in Texas showed relative abundances as high as chats per route in the Pineywoods and southwest Edwards Plateau regions. Chats also breed in the texas, but in much more scattered sites and lower relative abundances.

The low texas of confirmed evidence is not surprising since most chat nests are well concealed in dense vegetation. This band of breeding sites extends north into Oklahoma, where almost all breeding sites are in the easternmost quarter of the state Versaw This area in the two states probably represents the eastern subspecies, I. A second subspecies breeds in the western North America and chat Texas. Corman and C. Wise-Gervais, eds.
In spite of their apparent chat from wood- warblers, genetic studies place the texases within the wood-warblers, although not close to any other species.
