Answer

Behavioural responses to cope with variations in their environment are shown by few animals.
Desert lizards manage to keep their body temperature fairly constant by behavioural adaptations. They bask in the sun and absorb heat, when their body temperature drops below the comfort zone, but move into shade, when the ambient temperature starts increasing. Even snakes also show basking during winter months.
Since they are ectothermic, this kind of behaviour saves them from extreme temperatures.
Many smaller animals show burrowing behaviour to adapt to the temperature extremes.
Some species burrow into the sand to hide and escape from the heat.
Migrations shown by the birds and mammals are also behavioural responses for adapting to severe winter temperatures.
