27 March 2017 – PNW Migration Update

This is way past getting old so lets not discuss it.

Black-headed Grosbeaks in San Diego, Ospreys, Rufus Hummingbirds, and most Swallows are firmly established in the Metro Region.

Elsewhere at the national level we can see the SE and Gulf Coast hopping.  A few storms to dodge here and there but plenty of open air.  Thanks Paul!

18 March 2016 – PNW Migration Update

Well, it would appear waterfowl are on the move.

Looking at last night’s radar we can see low level migration but with 20+ dBZ patches coming from the Counties of Benton/Polk/Marion and Multnomah/Clark (WA).  Which are home to Finley/Basket Slough/Ankeney (FBA) NWR, and Sauvie Island WMA/Ridgefield NWR.  Note how the birds that take off from FBA split.  Some head to the coast and some head up the valley.  Curious.  There is also a slug of migrants heading up the western slopes of the Cascades.  Again, curious.

It’s a very interesting radar image today, but exactly what is going on is all speculation.  Tomorrow we’ll take a look at Paul’s national radar composite.

In the Region: Rufus Humming Birds are now being reported and a Loggerhead Shrike was reported on the east side of the Cascades.

South: Swainson’s Hawks have made it to the Central Valley and a Bullock’s Oriole has also been reported there.
