|a The Mojave Desert is one of the driest and hottest deserts in North America. One would expect that birds living in this desert would be specialists adapted to survive such an environment. However, most of the avifauna present in the Mojave Desert range into cooler, more-humid regions. We report observations of horned larks (Eremophila alpestris) using burrows of the desert tortoise (Gopherus agassizii) during summer as refugia from hot above-ground temperatures. We show that horned larks appear selective of the micro-environment they choose and that burrows are the coolest, most-humid, microsites available. By using burrows of desert tortoises, horned larks may reduce evaporative water loss by ≤65% and they may avoid physiological stress, or potentially death. Additional research should investigate the importance of burrows of desert tortoises to other species as it is likely to provide a key microhabitat to many species that reside in the Mojave Desert. El desierto Mojave es uno de los más secos y calientes en Norteamérica. Se pensaría que los pájaros que viven en este desierto son especialistas adaptados para soportar ese ambiente. Sin embargo, la mayoría de la avifauna del desierto Mojave tiene una distribución geográfica que se extiende a regiones más frescas y húmedas. Reportamos observaciones de alondras cornudas (Eremophila alpestris) usando madrigueras de tortugas del desierto (Gopherus agassizii) durante el verano como refugio de las temperaturas altas en la superficie del suelo. Enseñamos que las alondras cornudas parecen discriminatorias del micro-ambiente que escogen, y que las madrigueras son los sitios más frescos y húmedos disponibles. Al utilizar las madrigueras de las tortugas del desierto, las alondras cornudas pueden reducir la pérdida evaporatoria del agua hasta 65%, y pueden evitar estrés fisiológico, o potencialmente la muerte. Investigación adicional debe evaluar la importancia de las madrigueras de las tortugas del desierto para otras especies porque es probable que provean un micro-hábitat a muchas especies que habitan en el desierto Mojave.
