As of 0400 UTC Sunday, October 1, 2017, KRTX radar continues to experience signi
ficant technical issues which prevent the reliable operation of the radar. Howev
er, KRTX has been repaired to the point where NWS Portland can run the radar a f
ew minutes at a time before KRTX fails again. Until further notice, this will on
ly be done for testing purposes or if threatening weather approaches. /Weagle

Yeah, that sucks.

On the ground:

Timothy Lake had tons of Western Grebes, reports of dozens of Common Loons on Saturday but i didn’t see any on Sunday but it was raining pretty steadily, Barrow’s Goldeneye are still on the lake and a lone Red-necked Grebe was seen.

On the valley floor Varied Thrush and Dark-eyed Juncos are moving in, i saw, and most remarkably heard still singing a Ruby-crowned Kinglet, Fox and Golden-crowned Sparrows are increasing in numbers, Cackling Geese are being reported into the thousands, Sandhill Cranes are into the hundreds, a few Mallard and Green-wing Teal males are coming out of eclipse, House Wrens and Western Wood Pewees are apparently gone.  Still no reports of Buffleheads.

Since RTX is down i’m throwing in the loop for ATX (Seattle).  We still have solid movement through out the Sound and most noticeable across the Strait.

18 September 2017 – PNW Migration Update

There is not much to see on the radar due to the clouds and rain so we’ll save some disc space today and leave out the radar loop.

Over the weekend FOS  and changes noted: Sandhill Cranes are back by the hundreds, Great Egrets are staging in the hundreds, Cackling Geese numbers reaching the thousands, Golden-crowned and Fox Sparrows are showing up, Lincoln’s Sparrow and Dark-eyed Junco numbers are increasing on the valley floor as they come down out of the mountains, and Double-crested Cormorants are moving inland.

I probably missed a few as well.

A static shot of the National Radar Composite shows the very active Mississippi Flyway but with good movement down the Atlantic and moderate movement along the Central Flyway

19 September 2016 – PNW Migration Update

Well, after a pretty miserable few days it looks like the current system weakened a bit last night.  We still had onshore crosswinds but the birds were on the move in the metro area last night.  It didn’t sustain heavily through the whole night and again the east counties had most of the action.

Quite a few more ducks are being reported.  The Sandhill  Crane numbers have dramatically increased on Sauvie Island.  I’ve been quite busy so i wasn’t paying attention to the listserves last week.  I only got out into the field once this weekend and it was pouring rain, so it was a short trip.  But there were quite a few Swainson’s Thrushes moving just before dawn.

23 October 2015 – PNW Migration Update

The stubborn ridge of high pressure is keeping the local winds out of the north.  but i don’t see that lasting too long as another low pressure system is spinning up out it the Pacific.  You can see this on today’s wind map.

Over all the southern reaches of our area of concern saw the best migration action last night; again, it was concentrated along the flanks of the Cascades and east of the Willamette.  There was a short but heavy flight across the Straight of Juan de Fuca last night as well.

Still haven;t heard of any Swans in the area but the Cranes are on the move in good numbers.  They even were reported in Clackamas County — not a common report by any means.
