During the day coyotes are elusive and hard to find, but at night they become much more active. It is at this time that they often howl and are a source of annoyance to people who live in or near them. However, there is a good reason for this; it is the only time of day when resources are easily found.
The answer to the question of where do coyotes sleep at night depends on a number of factors, including environment and terrain. For example, in open areas they tend to sleep on high ground and in the cover of bushes or trees. They also tend to choose a spot that is away from the wind.
If they have pups, they may dig a den for themselves or use an existing burrow (often one created by raccoons, badgers, skunks or other medium-sized carnivores). They prefer some type of defensive cover at the site such as bushes, rocks or trees and a slope for drainage. During the winter, mother coyotes will sometimes move their young from den to den to protect them from harsh weather conditions.
It is important to remember that while they prefer to sleep in natural locations, coyotes are extremely adaptable. They can survive in a wide range of environments from prairies and deserts to forests, mountains and even cultivated areas like farmlands. They have even been known to live in cities. This is why it is always wise to be careful when you are close to a coyote.
