28 April 2017 – PNW Migration Update

I think it is a season’s first, but maybe not.  There is a big high pressure system out in the Pacific, centered west of California.  But it is big enough to throw north winds down the I5 corridor.

Combine that with marginal, at best, weather the last couple of days and you get the lack luster migration we’ve been seeing.  Birds are on the move, just not enthusiastically.

So, we’ll look elsewhere:

26 April 2017 — PNW Rain Report

It’s going to continue to be VERY rainy.  All kinds of known records are being broken from San Fransisco to Vancouver BC, and it is not going to let up anytime soon.  Cliff Mass deserves a permanent link and i’ll get around to it.  In the mean time, go ahead and check out his weather blog.

I have no idea how the birds are picking their way north but they continue to slog their way through the dreary.  Some reports of early Western Wood Pewee and Olive-sided Flycatcher and one “dubious” report of a singing Swainson’s Thrush.

There are no regional radar loops worth looking at over the last couple of days, so i am going to save disk space.

Oh, hey Wedgwood – throw me a life preserver if you have one to spare.

24 April 2017 – PNW Migration Update

Personally, i am really tired of: 1) being time constrained due to obligations during the work week and 2) RAIN.

I only have one static image from Friday/Saturday, when it wasn’t raining for most of the night, that shows a really nice flight up the Pacific Flyway.

But birds are finding a way to push north.  Lots of new arrivals: American White Pelican, Black-headed Grosbeak, Warbling and Cassin’s Vireo, Wilson, Yellow, Hermit and Nashville Warblers, all expected Empids, Western Tanager, Vaux’s Swift, Cinnamon Teal, Sora, American Bittern, Bullock’s Oriole, Western Kingbird and in San Diego Lazuli Bunting.

A lot of these birds are slightly ahead of schedule

21 April 2017 – PNW Migration Update

Well, a relatively clear night with light winds out of the south and you would expect a surge of migrant activity.  But it was really rather muted.  We did get a smattering of 20+ dBZ returns; i just expected a much deeper and widespread response.

Arrivals, or increased reporting: Vaux’s Swifts and Wilson Warblers.

Two notes — another well organized low is headed our way (read, more rain) and there was a pretty interesting flight path down the Columbia and out to the coast that can be seen in last night’s loop; i don’t recall seeing that before.

Rain.  So take a look at a static shot of the national radar composite instead.

Thanks Paul!

18 April 2017 – PNW Migration Update

Crimony. Is it ever going to stop raining?  Thank goodness we have a president that is gutting all of out climate change initiatives and research.

Anyway, we can see some decent movement between the rain cells here in the Metro area.  But if you want to see really dodgy flight behavior take a look at the Aberdeen (ABR) loop i put in the gallery today! And a static shot of the National Composite — lots going on last night.

Western Wood Pewees in San Diego, while up here: more Nashville Warblers, Yellow Warblers, Black-headed Grosbeaks, Warbling Vireos and even a Hermit Warbler.  All pretty much on schedule.  Shorebird migration is underway as well.

17 April 2017 – PNW Migration Update

Friday through Sunday: Friday not so much, Saturday bada bing, Sunday ??? the radar is wonky.

Friday/Saturday the rain kept our friends pretty much grounded; some decent movement but on the  light side.

Saturday morning i went into the coast range and found the Sooty Grouse, Mountain Quail and Gray Jays calling. Didn’t see either chicken but the Jays were conspicuous. My usual transect is being radically altered by logging and i did not hear one Red-breasted Nuthatch; lots of Orange-Crowns but still a bit early for MacGillivray’s or Hermit Warblers.

Saturday/Sunday was the first green doughnut of the season.  I went out to Sauvie Island on Sunday morning and i have never seen so many butter-butts; there were thousands of them.  As one woman said when i facetiously asked her if she’d seen any Yellow-rumps today, “Good Lord! I’ve never seen so many!”  And there was a smattering, but decent representation of Organe-crowns and Black-throated Grays as well.  Golden-crowned Sparrows are thinning out, the Purple Martins are back as well as the House Wrens.  Some sneaky Starling tried to trick me into thinking the Western Wood Pewees were back as well, but fool me once ……

Last night, Sunday/Monday, the radar only picks up around midnight; not sure what that’s about but we can see a decent flight for a bit.

A reported influx of Hammond’s and Pacific Slope Flycatchers hit the Metro area this weekend. Nashville Warblers and Cassin’s Vireos also showed up on the listservs.
