12 April 2017 – PNW Migration Update

A solid night of ….. rain.  I’m sure birds are slipping through, we just can’t see them.

So i put in the National Composite (thanks Paul) and the wind map.  A good study today about migration and weather.  Big flight up the Central Flyway,  shut down behind the squall line but advancement up the Atlantic Flyway ahead of the weather.

Central Valley is reporting Bullock’s Orioles, Black-headed Grosbeaks, Purple Martins, House Wrens, Wilson’s, Nashville and Yellow Warblers.  The Yellow and Nashville Warblers have made it to the Metro Area as well as the Purple Martins.
