After I finished checking out the boardwalk over near the Old Cedar Bridge in the Minnseota Valley NWR I decided to head north on the path that leads under the new Cedar Ave Bridge and over to the Bass Ponds.
The small trees that line the trail make for good habitat to search for warblers during the spring and fall migrations. During the summer you can still find a few warblers hanging around, usually yellow warbler or common redstart, as in this case.
You may expect a bird that is called a redstart to have some red coloration to it. This is true with the male of the species, which has reddish feathers on its wings, back and tail, but the female redstart, pictured here, has yellow color instead of red.
They use these colored feathers on the wings and tail by flashing them to startle insects. When the insects flush the redstart is there to reap the rewards.
