Habitat features found within 4.1 ha sample areas surrounding the song perches of 33 Indigo Buntings (Passerina cyanea) and 33 Painted Buntings (Passerina ciris) in northeast Texas were compared to determine whether these species segregated according to habitat. The species did not differ in the proportions of open habitat or the type and amounts of successional and mature woodland in the sample areas surrounding their song perches. Indigo Buntings were mostly associated with lower elevations where they occurred along the edges of successional and mature woodlands. Painted Buntings showed no elevation bias. Compared to Indigo Buntings, Painted Buntings were associated with smaller, more numerous, and more heterogeneous stands of trees. In general, Indigo Buntings typically occurred where there were open areas within otherwise wooded habitats whereas Painted Buntings tended to occur where there were wooded areas in otherwise open habitat.
