The life span of a black crow on average is 6 to 9 years. Unfortunately, over 50 percent black crows die during their first year of life.
Fully grown crows have very few predators with humans and hawks being the biggest threat to the birds. Young crows however, are susceptible to a large array of predators including owls, raccoons and other animals. Many young crows die from starvation or adverse weather conditions.
There are many species of crow around the world and they live in a variety of habitats, including urban areas. Crows are omnivores, so they will scavenge and eat whatever they can find.
