Worm-eating Warblers are common on our property in near the Missouri River. There are several breeding pairs, most of which favor the sides of forested, steep ravines. Worm-eaters usually arrive here about mid-April, about the same time as the Morel Mushrooms begin to appear. A double treat for my wife, Dayna, and me! These males were filmed during April and May of 2009 and 2010 in central Missouri:
The trilled song of Worm-eating Warblers is very similar to that of Chipping Sparrows, but you can usually guess which species you are hearing by the habitat. Worm-eating Warblers favor dense woodland, where Ovenbirds and Northern Parula Warblers are also common. Chipping Sparrows are common in more open habitats and often come to feeders. Worm-eating Warblers breed in the eastern third of the United States.
