Why do lizards and other small animals living in the desert climb to the tops of bushes in the hottest part of the day?

In this way, lizards and small animals are saved from the heat. During the day, the sun turns the surface of the earth into a hot frying pan, and you can escape from it either by hiding in the sand, a mink, or by climbing to the tops of bushes. At the tops of the bushes, the temperature is much lower than on the sand. This is the main reason why lizards and small animals climb and sit on them.
