Bewick’s Wren (Thryomanes bewickii), Yellow-billed Cuckoo (Coccyzus americanus), Golden-fronted Woodpecker (Melanerpes aurifrons), Ladder-backed Woodpecker (Picoides scalaris), White-eyed Vireo (Vireo griseus), and Verdin (Auriparus flaviceps) are all residents of the South Texas landscape. While the species are unique in appearance, they share the diet of arthropods with each of these species categorized as an insectivore during the breeding season. During this time, they need more nutrients to keep up with the pressures of finding a suitable mate and maintaining their young. The objective of this study was to investigate the influence of brush cover and arthropods on avian insectivores in native rangelands of South Texas.
