They usually do so when the temperature is warmer and will re-emerge in the late summer or early fall. [5] Mosquitoes also are reported to undergo aestivation. [6] False honey ants are well known for being winter active and aestivate in temperate climates. Bogong moths will aestivate over the summer to avoid the heat and lack of food sources. [7]

In temperate regions of the southern hemisphere, where seasonal cold temperatures are not as extreme or long lasting, freeze tolerance is more common. [ 2 ]
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature.

Sunning or basking, sometimes also known as sunbathing, is a thermoregulatory or comfort behaviour used by humans, animals, especially birds, reptiles, and insects, to help raise their body temperature, reduce the energy needed for temperature maintenance or to provide comfort.
Meat chickens: Free-range broilers are reared for meat and are allowed access to an outdoor range for at least 8 hours each day. RSPCA standards state that in order for chickens to be free range, there must not be more than 13 chickens per square meter. [ 23 ]

The legs are yellow and unfeathered. The beak is yellow or horn-colored. [6]: 69 The back is long and broad, and the breast fairly deep. [14]
