FIR ISLAND â From atop a dike Monday morning on Fir Island, Skagit Audubon Society President Jeff Osmundson and group member Tim Manns could identify the birds in all directions. A great blue heron to the north, a bald eagle to the south, snow geese flying overhead and dozens of dunlin flocking to the exposed shore of Skagit Bay â to name a few. Manns and Osmundson trained their spotting scopes on each species for U.S. Rep. Rick Larsen (D-Everett) while they rattled off facts about the birds most often seen in Skagit County. Larsen is touring birdwatching sites with Audubon Society groups in the stateâs 2nd Congressional District because heâs concerned about an upcoming change to the Migratory Bird Treaty Act.
