Crepuscular animal group (active in the dim light) or nocturnal (active at night) spend time in the night to avoid heat
Summer as it is today often has an unfavorable impact on living things.
No wonder when various ways are chosen to protect themselves from the heat of the sun. Most animals, for example, will choose to avoid heat.
Being crepuscular or nocturnal is a fundamental way to avoid heat.
Crepuscular animals, such as a small North American cat species called bobcat, will only live actively in the cold twilight times.
While nocturnal animals, such as forest dogs will become more active at night. So the animals do not have to deal with the heat in the daytime.
