29 March 2016 – PNW Migration Update

Continuing north winds probably hampered migration a bit, but not completely.  There was a nice push of birds in east Clark County probably originating from Steigerwald.

Looks like this ridge of high pressure may stick around for a while.  That will bring some much needed relief from the rain, but as long as it hangs in the Gulf of Alaska we will continue get these north winds aloft.

One glance at the Winds of the Earth and you can pretty much guess the Central Flyway and possibly the southern part of the Atlantic Flyway is set up for decent migrating conditions.

Black-headed Grosbeaks have made it to San Diego, Common Yellow-throat and Northern Rough-winged Swallows to the Willamette Valley.
