The gyrfalcon is a casual bird this far south. But if you are going to see one in Oregon, the place to look is along the dunes and beach to the west of the spit road. These magnificent raptors have been seen a number of winters. Another apparently favored spot is the small bay east of the road. There is also a parking areas with some small ponds just to the west and north. These ponds are superb for shorebirds.
Walk out to the base of the jetty and scan over the water to the south. Landlubbers should know that Clatsop Spit is an outstanding place to see pelagic species without risking seasickness.
