17 March 2017 – PNW Migration Update

First clear night in a LONG time and winds out of the south = a pretty decent and widespread movement of north bound migrants.  Decent enough that i even put in the loop from Gray’s Harbor (LGX)

Looking at the wind map we can see why there was very little movement up the Atlantic Flyway and some decent flights up the Central Flyway.

A few shorebirds are popping up, swallows are becoming more widely reported including early vanguard Cliff and Northern Rough-wing, and the Snow Goose numbers are way down on Sauvie Island.

04 November 2016 – PNW Migration Update

Light north winds but clear skies, even with migration winding down, we still have a few migrants moving south.

With RTX off line we’ll take a look at the other two regional radars today; ATX in Seattle and LGX on the coast at Gray’s Harbor.

21 September 2016 – PNW Migration Update

BOOM!

Favorable north winds bring; Spectacular, heavy and widespread migration last night.  From the Canadian border down the I5 corridor, and up and down the region’s coast line.  Take a look!

Note on the RTX loop at the beginning and the end we again see the activity of the Barn Swallow hoards along the Willamette River.

20 September 2016 – PNW Migration Update

Light but favorable winds over the region last night, especially along the coast.

Again most of the action was in the east Counties along the spine and western flanks of the Cascades.  There was a nice, and interesting flight from Vancouver Island that washed down the Olympic Peninsula coast line (LGX radar). I don’t recall seeing such an organized flight in this area before, but don’t hold me to it.  On the ATX radar (not shown) it was weird; it seemed there was little movement except at moderate levels restricted to the shores of the Puget Sound.

If i had the day off i would head up to the Cascades and check out Clear and Timothy Lakes.  I see the divers are starting to arrive; there have been reports of C. Loons and RN Grebes come in to the review queue this morning. (Timothy Lake)

12 September 2016 – PNW Migration Update

Migrants are feeling the call south.  With winds out of the east, probably from temperature differentials, the cross winds did not slow the birds down last night.  The upper left hand corner was jammed with southbound sojourners.

The first Cackling Geese are being seen, wintering pink-footed gulls are pushing into the valley and more early Golden-crowned Sparrows are popping up here and there.

09 September 2016 – PNW Migration Update

Excellent night for migrant flight!  The I5 corridor was just jammed with birds last night; from the Canadian border to the Metro Area and from Cape Flattery to Fort Stevens — bada bing.  Heaviest migration of the season.

The high pressure ridge is getting a bit smooshed by a low in the Gulf of Alaska but it should hold up for another day at least.

08 September 2016 – PNW Migration Update

Decent flight last night in the Metro area and widespread as well.  I looked at Seattle and Grays Harbor — not so much happening.

Anyway, there is a big high pressure system spinning up offshore.  The leading edge will bring favorable winds and it is just making landfall.  So that should carry us through the weekend.

Haven’t had the time to check the listserves closely so i am not sure what’s new in town.
