Wilson’s Warblers Song:
Nests of Wilson’s Warblers are well hidden on the ground near trees or shrubs and made from leaves and sedges for the base. Grass, bark, moss, and plant material are woven into a cup shape and lined with soft grass and animal hair.
They lay around five eggs which take about eleven days to hatch and an additional ten days for the young to leave the nest.

Wilson’s Warblers distract potential nest predators by pretending to have a broken wing and drawing the predator away before flying off.
