19 March 2018 – PNW Migration Update

There is continued light movement up the valley. Probably waterfowl re-positioning.

There has been really nothing to report in the new arrivals, but on the “it’s just around the corner” front:

Increasing: Rufous Hummingbirds, Turkey Vultures and Ospreys, Tree and Violet-green Swallows.

Bushtit flocks are breaking up and singlets and doubles are now being seen.

Ruby-crowned Kinglets can now be heard singing.  This is a special time as they will soon be gone and their’s is one of the most glorious songs.

Waterfowl numbers are shrinking as well.

We’ll save some disk space and not post a radar loop today — it’s just sub 10 dBZ blue.


12 March 2018 – PNW Migration Update

Rufous Hummingbirds have made it to the Portland area.

Bullock’s Orioles are in Merced Co. in the Central Valley.

Lots of birds are on the move; most likely waterfowl beginning to head north.

The Pacific Flyway continues to have very light migration, it is just a trickle down the Central Flyway, the Mississippi Flyway had some serious weather, but the Atlantic Flyway is still rocking.

26 October 2017 – PNW Migration Update

I’m still not seeing the duck numbers i expect but the Cackling Geese have DEFINITELY arrived.  I saw 2 to 3 thousand of them yesterday in the rural fields of Clackamas County.

But the number of migrants wanes:

23 October 2017 – PNW Migration Update

First clear night since the last update and it was, as expected, a moderate event.  We still see good movement on the western flanks of the Cascades and a nice pulse mid-valley probably associated with duck and goose movement between the NWR’s.

I’m not seeing much except coastal movements on the listserves. I got out into the field a little this weekend; found a large flock of Pine Siskins, and had about 30 gulls around the Willamette Falls area – one Western, one Herring, and 28 Olympic, no Icelandic and no pure(ish) Glaucous-winged.

18 October 2017 – PNW Migration Update

The slowing of migration continues.  In fact it is barely noticeable in the Portland area.  So we’ll take a look at the ATX (Seattle) radar where the migration returns are more pronounced, especially across the Strait.

17 October 2017 – PNW Migration Update

Another low density night.  Two in a row signals the waning of the season.  There’s still plenty of ducks to show up but they might just trickle in.

A weather system is headed in from the Gulf of Alaska.  Adventurous birders could scour the coast for oddball Asian vagrants.  Not my cup of tea but, just saying…
