15 apr 2014 PNW Migration Update

With winds shifting to WNW the pace of migration abated a bit last night.  Or perhaps they were spooked by the blood moon.  Either way the march north continues just at a slower pace.

All of the swallows have been reported, a Western Flycatcher, and reports to our south on the appearance of Wilson’s Warblers.  Here they come.

Here is Paul’s archived National Radar Composite from yesterday.  The SE coast, a couple of spots in New England and along the Pacific Flyway.  But other than that, the Northerlies had the birds sit last night out.
