06 September 2017 – PNW Migration Update

RTX is back on line but there is so much smoke and ash in the air it is probably unreliable.  It is also possible that the birds are not flying into the area to avoid this crap.

Up in Seattle there were some isolated movements, notably off the southern tip of Vancouver Island.  Usually i see these birds head directly south into Clallam County but the birds last night headed SE into Kitsap — odd…

Anyway, the movement would best be described as light.

RTX is still off-line.  We’ll use ATX again today.

Looks like a slight up-tick in activity last night, but that may be just birders flocking to the MEGA rarity that showed up yesterday.

Either way, the returns are a bit brighter showing more density.  For the last couple of nights i have been hearing the nocturnal flight calls of Swainson’s Thrush as they pass overhead.

Local radar, KRTX, is down for scheduled maintenance:

“The KRTX National Weather Service Doppler radar will go down today, August 28th,
through the remainder of this week for the second phase of upgrades to the rada
r which started last October. We anticipate the radar will return to service at
some point on Friday, September 1st. PT 8/28/2017 619 AM PDT 1319UTC.”

Regional winds are light and generally out of the north.  The Seattle radar, ATX, shows decent movement throughout the Sound and across the Strait.

Nationally birds are on the move, filling in behind Harvey.  There are still significant winds arcing over the Gulf States so Louisiana to Florida are dark.

Minimal movement last night in the Metro Area.  The onshore flow might have been a deterrent.  There was a nice flight across the Strait again so birds are on the move – just not widespread yet.

One extreme migration event took place in the Nashville area last night where the returns were pushing 35 dBZ!

I did see the first Green-winged Teal of the season this weekend.  The males are still in eclipse plumage so this is an early group.

Well now, things are picking up. We’re getting some solid flights that i would categorize as moderate.  Plenty of green (around 20dBz) but not widespread.  Lots of movement on the perimeter of the Puget Sound, a nice wave of migrants across the Strait, and the west flanks of the Cascades.

The local breeders have dispersed and territorial songs have subsided.  Kind of the dog days so it will be good to see if i can kick up some early arrivals this weekend up in the Cascades.

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.
