Forster's Tern on Shenandoah River--Again!

This afternoon was overcast and drizzly, so I decided to make a quick check of the Shenandoah River, Jefferson County, on the way home from work. Imagine my surprise when one of the first birds I spotted was a Forster's Tern perched on a log with three Double-crested Cormorants--my second observation of this species in the Eastern Panhandle in 10 days. This was just south of the Route 9 bridge along John Rissler Road. I noted a total of 8 waterbird species south and north of the Route 9 bridge, as follows:

Red-necked Grebe 1 (1 south of Route 9 / 0 north of Route 9)
Double-crested Cormorant 22 (7 / 15)
Canada Goose 16 (10 / 6) - including 3 apparent Canada x White-fronted hybrids
Wood Duck 4 (3 / 1)
Green-winged Teal 1 (0 / 1) adult male
Ruddy Duck 10 (0 / 10) about 50:50 males (in full breeding plumage) and females
Forster's Tern 1 (1 / 0)
Belted Kingfisher 1 (1 / 0)
