30 Apr 2014 PNW Migration Update

Mild winds out of the east driven by a pressure differential did not deter the northbound train.  Another night of “Green Doughnuts”  I’m getting the first reports of Yellow-breasted Chats in the Central Valley.  I haven’t heard of any Lazuli Buntings yet, but i may have skipped a listserve or two.
