American Avocet
In response to predators, the American Avocet sometimes issues a series of call notes that gradually changes pitch, simulating the Doppler effect and thus making its approach seem faster than it actually is. Nesting American Avocets aggressively attack predators, sometimes physically striking Northern Harriers or Common Ravens. American Avocet chicks leave the nest within 24 hours after hatching. Day-old avocets can walk, swim, and even dive to escape predators. he oldest recorded American Avocet was over 15 years old, when it was found in California, where it had been banded a decade and a half earlier.
