It's about 4:30pm, and I am watching what I believe are 5 Black Terns as seen
from the Hunting Creek Bridge in Alexandria in the middle of the river looking
toward the Ferris wheel. All of the birds have all dark wings and back,with
one bird having a dark belly. Never plunge-diving like the Forster's Terns on
the river.
I've tried unsuccessfully to get decent digiscoped pictures.
