The avian visitors are a pair of Mississippi Kites, a species that can be seen annually in the second half of May here in the north when their migration overshoots their typical breeding range of the Carolinas. Usually these sightings are in the southern part of New Jersey and last for just a few days. So to have these birds appear this far north, and as a pair was quite unusual.
