Coyotes are not strictly nocturnal. They may be observed during the day, but are generally more active after sunset and at night. You may see and hear coyotes more during mating season (January - March) and when the young are dispersing from family groups (October - January).
Coyotes eat what is prevalent and easy to find, shifting their diet to what is seasonally or locally available, including rodents, birds, vegetation, and insects. Like birds of prey, coyotes help to control the population of rodents in the City.
Coyotes are canines, which means that they are genetically related to wolves and domesticated dogs. In general, coyotes appear "sleeker" than domesticated dogs, with a flatter forehead and a more pointed snout. Coyotes appear to have longer legs than domesticated dogs, while dogs appear to have deeper chests. Also, they have very different tracks. Coyote tracks are more elongated, and they place their front and back paws in alignment when they walk.
Don't be alarmed if you see a coyote in the wild, but do be alert.
