We studied the thermal ecology of northern bobwhites (Colinus virginianus) to better understand the role of temperature in the field behavior of these birds. We obtained descriptive data on thermal aspects of the landscape; bobwhite selection for Normalized Difference Vegetation Index (NDVI; vegetation biomass) classes and cover associations relative to their thermal properties; and thermal conditions at nests, mid-day coverts, and roosts. We collected data on 796-ha area in the Texas Rolling Plains during May 2000-July 2003 using satellite imagery, black-bulb temperature probes, mortality- and temperature-sensing radiotransmitters, and continuous-recording video cameras for nest observations"--page 1.
