The pair bond is maintained with impressive courtship displays, where the pair locks talons in mid-air and somersaults downward. Both parents incubate eggs and care for nestlings. The pair may also hunt together to tire their prey or to pirate fish from ospreys. Bald eagles will also harass vultures to force them to disgorge food. Just recently, the bald eagle was downgraded in status from federal endangered to federal threatened.
