American Avocet

The American avocet (Recurvirostra americana) is a large wader in the avocet and stilt family, Recurvirostridae, that is found in North America. It spends much of its time foraging in shallow water or on mud flats, often sweeping its bill from side to side in water as it seeks its crustacean and insect prey. The call has been described as both a shrill and melodic alarm bweet, which rises in inflection over time. Avocets use three distinct calls: common call, excited call, and broken wing call. The common call is a loud repeated wheep. The excited call has a similar wheep sound, but it speeds up rather than having an even rhythm. Lastly, the broken wing call is noticeably different from the other two calls. It is a distressed screech sound and is alarming rather than melodic.
