Adaptation of animals from the heat.

The main strategy for dealing with high desert temperatures is avoidance – many mammals simply avoid high daytime temperatures by being nocturnal (active in the dark). For example, the lynx is generally most active at dusk and dawn. Even daytime active birds are most active in the cold dawn. Many mammals, such as kangaroos, are never active during the day.
Another avoidance strategy is to seek a cool microclimate. The wren can safely rest in the shade; the rocky falcon will nest on the cool northeast ledge and avoid the hot southern sun.
