Prothonotary Warblers Song:


Nests of Prothonotary Warblers use abandoned woodpecker nest holes in trees that are near water. Males place moss in the hole, and then the female makes a cup-shaped nest from grass and leaves, and other plant material.

They lay up to seven eggs which take about two weeks to hatch and an additional ten days for the young to leave the nest.
