After each fledging class of blue birds, I remove the old nest to try and keep the box clean and parasite free. This bird has tried to take advantage of the clean box and set up house keeping. We are not sure what bird this is.
Our best guess at this point in time is Bell’s Vireo but since we have never seen a Bell’s Vireo and the Cornell Bird site pictures show a bird that has more yellow in the belly, we can not be sure.
Any help is appreciated.
