One bird of prey may steal another's meal, a behavior that biologists call piracy, or kleptoparasitism.
The prey may change hands several times, perhaps from Northern Harrier to Peregrine Falcon to Bald Eagle. The Peregrine - like the young one seen here - may steal a meal, or have its meal stolen, or both!
