Last weekend we had three of those four species end up in our nets. Easily identified by the stripe pattern on it's face is the Red-eyed Vireo.
The ability to separate the Warbling Vireo from the Philadelphia Vireo can be more difficult. Both were in our hands and there are a couple of things to look for that separate the two.
With the weather continuing to be warm and dry this weekend should be good for getting out into the field. The Warbling Vireos should just about be gone but the Philadelphias and Red-eyed will be moving through for a while yet. The next big group will be sparrows!
