In June I found several redstarts nesting by the Old Cedar Avenue Bridge in the Minnesota Valley NWR. The female redstarts are less colorful then the males which makes them a bit harder to find. This female was carrying feathers probably for nesting material.
The nest is cup shaped and usually made of grass, bark,leaves, sticks, moss, feathers, and spider webs. The nest is fitted between the branches of a tree or large bush located in a wet deciduous forest with plenty of bushes for hunting insects.
During the winter these birds migrate south, most ending up in southern Mexico or South America, although there is a small percentage that will winter in southern California or Florida
