The white-eyed vireo's call
The white-eyed vireo call is sharp and described as 'quick-with-the-rain-check'. The song consists of about six to seven notes in which the first and last notes are diminutive and sharp, whereas the central notes are a quick trill.
In the breeding season, males sing this song to attract females. Young birds learn their father's song at the very beginning of their life and also try to mimic the song after they leave the nest.
They also modify their song by joining some elements from the neighbor's song. When the birds see a predator they produce a harsh call to scare them.
A breeding pair gives each other a small 'pik' call to contact each other. If these birds are captured or handled by human beings, they emit a rough squeal to alert their mate or to frighten humans.
