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.

10 May 2016 – PNW Migration Update

Winds eased up a bit and shifted to a NNE direction, pushing coastal migrants offshore a bit.  And with that migration picked up as well.

Still waiting to hear of Willow Flycatcher arrivals.  There’s been one report for the metro area — closest other Oregon report is one from Skinner Butte in Eugene. I find this type of dispersion, well, curious.  The next closest report is way the hell down in Bakersfield at the south end of the Central Valley.  Their average arrival date is 13 May, so maybe they are running a bit late this year?  HERE is the 2016 distribution map.

Western Wood Pewees have been around for a couple of days.

11 April 2016 – PNW Migration Update

Since i take the weekends off from this project i’m not sure what the birds were up to Friday and Saturday night.

But i do know what they were doing in the field.  Duck numbers are down, Snow Geese are gone but there are plenty of Cacklers still around.  A few more shorebirds are around.  The snipe are winnowing, Sooty Grouse are booming and a few cranes are practicing their mating dance.  Common Yellowthoats are firmly entrenched. Chipping Sparrows are dotting the landscape.  And northbound Blue-winged Teal are popping up in their usual low density numbers but to the delight of those who happen upon this strikingly beautiful bird.

On the listserves; MacGillivray’s Warbler, Black-headed Grosbeak, and Western Tanager have made it to the Willamette Valley.

Outliers of Hammond’s Flycatcher, Swainson’s Thrush and Western Wood Pewee have been reported as well.  Treat those as you will.

Last night we had light to moderate migration across the region so i am going to conserve cloud space and only put in the RTX loop today.  LGX and ATX both had approximately the same density.

08 April 2016 – PNW Migration Update

Unfavorable but light winds did not deter migrating birds.  Most of the action was up in the Seattle area with a very strong flight across the Strait of Juan de Fuca.  Also, a significant movement along the coast.

Sora, Chipping Sparrow, Black-headed Grosbeak and Western Wood Pewee have now been reported in the northern Willamette Valley.
