Sorting gulls this morning at Carter Lake, Iowa, we were startled by the sudden appearance of an adult Peregrine Falcon, which flashed past us to land on a hapless Killdeer. It took off with its squirming prey, only to find itself beset by a brash immature Herring Gull, which chased it acrobatically until it dropped the Killdeer, which flew a short distance and dived into the water, only to be plucked from the surface by a 3rd-year Bald Eagle! The eagle landed in the shallows and plucked and consumed the plover. What a way to go!
