However, one caveat: track down each singer at this time of year (spring migration).
You just don't know for certain unless the singer is seen. Habitat type is also helpful. If you are in the middle of State Forest lands and hear tons of incessant Red-eyed Vireo songs in the treetops, they probably are all Red-eyed Vireos. The tricky ones are those which are singing from mixed second growth habitat with lots of scrubby bushes and shorter deciduous trees (i.e., power line cuts/edges, old orchards, etc.), or which are singing from a suburban neighborhood...it can be very difficult to be 100% certain of ID by song without a sighting.

It's song was just as my son, Chris, described to me: like Red-Eye, but softer, higher pitched (squeaky), and at a slower pace. Perhaps it was a new overnight arrival that just happened to land near my house. After this, I had a difficult time getting back to sleep. Larry -- ================================ W.
