There are birds on the move but we’re not at peak densities yet; it’s still early. In the Gray’s Harbor radar you can see a small, short but intense return on the south shore; so maybe the shorebirds are getting antsy as they begin to stage for a push south.
Note the Winds of the Earth screen shot. The winds are favorably out of the north; yet the density of flight remains modest at best. A good sign that earnest migration has yet to begin.
