It is a slow week for migrants in Morris and Somerset Counties. Although not the most interesting tern in New Jersey at the current time (a Whiskered Tern is currently in Cape May), the Caspian Tern in the above photograph is the only one reported in Morris County this year. Two are reported from Somerset County in 2014.
The Caspian Tern was seen from Water Street at the gull roost location. Later, it was seen flying in the northeast corner of the lake near the park on Washington Street and later again, back at the gull roost. It will be assumed these sightings are of the same bird unless two are seen at the same time. Other birds at Lake Musconetcong are 2 Pied-billed Grebes, 80 Double-crested Cormorants, Merlin, Ring-billed Gulls and the usual 40+ Mute Swans.
