Black vultures are commonly seen in the skies over America’s southern and eastern states. They are gregarious, often seen in communal roosts or feeding on carrion, helping keep the environment clean. Adults form long-term monogamous relationships and typically have two fluffy, yellow-beige colored chicks each year. Adults share incubation and feeding responsibilities, and continue to feed their young for as long as eight months after fledging, helping to establish bonds among kin that last a lifetime.
