13 Mar 2015 — PNW Migration Update

Perhaps sensing the looming trough birds filled the airspace last night.

There isn’t any new migrant reports so this has to be staging waterfowl.  I am still puzzled about the density of birds headed up the spine of the Cascades.  Perhaps they use the Columbia Gorge to get to the east side?

Anyway, since it was a nice night to take wing and it looks like the next couple of days, maybe not so much, i put in all three PNW radar loops in today’s gallery.  RTX is Scappoose, LGX is Gray’s Harbor, and ATX is Seattle.
