Hello Everyone,

Yesterday (9/5/02) I searched for the Lesser Black-backed Gull from
sunrise to about 8:30 but did not see any dark mantled gulls at all.
Eagles kept the gulls in the harbor on the move.

Later in the day I stopped at Union at the Great Bend of the Hood Canal
and looked for the Franklin's Gulls that were reported there a few days
ago. I found one first winter bird with Mew, Bonapart's, Ringbilled
Gulls. Eagles kept these birds on he move as well.

Russell
