Temperature Dependent Behavior of the Cactus Wren

Field and experimental observations show that, as temperature become progressively hotter, Cactus Wrens select relatively cooler micorhabitats, and that after the minimum temperature reaches a critical level of stress, activity decreases. These results lead us to conclude that insectivorous desert birds such as the Cactus Wren are true xerophiles, since they show behavioral adaptations for existence in the desert in the face of limited water intake.
