21 Apr PNW Migration Update

MacGillivray’s, Nashville, Hermit and Wilson’s Warblers, Warbling Vireos, Western Kingbirds and Black-headed Grosbeaks.  All in the area or nearby pipelines.  I witnessed hundreds of butter-butts shaking the leaves on both sides of the Cascades this weekend.  Yep, it is full on barrage mode.

Friday-Saturday migration was “green doughnut” monstrous.  I have the loop saved but it is on a flash drive somewhere, so trust me on this one.  Saturday-Sunday was a bit more muted  but birds were still plodding north.  And last night?  Another “green doughnut” event!  20+ dBZ across the region.  A bit of weather coming ashore in Gray’s Harbor may have kept the coastal movement in check, but inland it was just wild.
