This wren is a secondary-cavity nester using natural cavities or woodpecker holes in trees, crevices in stone walls or buildings, nest boxes and even empty flower pots. This wren breeds in Texas from near sea level to 1100 m (3500 ft) in a variety of habitats in th eastern part of the state, especially those with thick undergrowth, often near water (Oberholser 1974). TBBA atlasers found 39 confirmed breeding dates from February 23 (a bird on a nest) to July 26 (recently fledged young).īREEDING HABITAT. Carolina Wren is a resident species in Texas, breeding from mid-February to late August (based on egg dates from February 26 to August 13 Oberholser 1974). Records were found at the edges of the South Texas Brush Country.ĭata from North American Breeding Bird Survey routes in the eastern United States indicate the primary range (more than one wren detected per route) extends from souther New England and the southern parts of Pennsylvania, Ohio, Indiana and Illinois, Missouri and eastern Kansas south to the Gulf Coast and into northeast Mexico (Howell and Webb 1995, Sauer et al. Further west breeding sites were much more scattered in the Rolling Plains and Edwards Plateau with a few in the High Plains. During the 1987-1992 field work seasons of the TBBA project, volunteers found most confirmed breeding records for Carolina Wren in the Pineywoods, Post Oak Savannah and Blackland Prairies, eastern Rolling Plains, eastern Edwards Plateau, Coastal Prairies and Coastal Sand Plain regions (see the region map in Lockwood and Freeman (2004).
