What is the male Wood Duck's distinct flight call transcribed as when pairing in late winter?

Answer

*jeeeeee* (a high-pitched whistle)

Wood Ducks possess a unique vocal repertoire distinct from the typical duck quack. The male's characteristic call, particularly noticeable during flight as they pair up late in the winter, is a high-pitched whistle transcribed as *jeeeeee*. This sound is critical for communication during pair bonding displays. This contrasts sharply with the female’s vocalizations; when flushed, females emit a rising squeal (*do weep do weep*), and for alarm, they use a sharper *cr-r-ek, cr-e-ek* sound.
