The Red-eyed Vireo is one of the most numerous birds in eastern United States forests. During breeding season it sings almost constantly, sometimes even at night. But, like other vireos, it isn’t seen very often because it stays high in the tree tops. It has a somewhat longer bill than the other vireos shown here. Of course, the red eye is diagnostic if you can see it in good light. This photo was taken in Itasca County, MN, during July, 2016.
