Turkey Vultures are fairly large birds with long, broad wings. Their colors are dark brown with a featherless red head and pale bill. They are graceful but unsteady soarers and fly low to the ground and have a great sense of smell. Turkey Vultures are scavengers and can be seen at roadsides, farm fields, countryside, and landfills. They help clean the environment by eating flesh off dead animals before they decay. Researchers have noted that turkey vultures can travel 200 miles a day. Their life span is up to 24 years old and they live in Southern, Canada, North America, and South America.
