The Use of Thermal Refugia by Two Small Desert Birds

Observations of diurnal microsite selection during the summer in the Sonoran Desert for two small insectivorous birds--the Verdin and the Blacktailed Gnatcatcher--are discussed. The potential effects of occupancy of these sites on avian water economy and rates of evaporative water loss are also exam...
