07 September 2017 – PNW Migration Update

Migration continues to be light across the region.  I’m sticking with the Seattle – ATX loop for today because: …

there is a curious morning flyout along the Sound where the Skagit River delta is.  It starts around 13:23 UTC (06:30 AM PDT) and lasts a little more than a half an hour.  I would guess a roost of Barn Swallows like the one along the Willamette River in southern Yamhill County.

Speaking of which; that roost’s flyout is also visible at dawn but it is not as dense as the one up in the Skagit delta.  In the years watching the Yamhill roost i never remember seeing it hit the 30+ dBZ range like the Skagit signature.

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.

Nighthawks have arrived in Oregon.  HERE is the map – not too impressive and these are the first arrivals to be sure.  But — This kind of ends the arrival notifications for the season; birds are still on the move however; they are settling in and looking for summer nesting locations; filling in the gaps.

It is the beginning of a long weekend and after that i will be far afield and unplugged.  There are a couple of days next week i will be checking in on migration; if i see anything pronounced i’ll post it — but i doubt that will happen.

Blue-winged Teal have been popping up here and there in the remaining wetlands throughout the region HERE  This is a spring ritual as they are late migrants and occasional breeders that winter to our south.  They are such magnificent birds it is always a treat to come across them.

The Mississippi Flyway is still electric when the conditions are favorable so we’ll take one last look at the National Composite Radar in today’s gallery as well.

Our ridge of high pressure is holding and we should have another day or two of this exceptional weather.  There is a deep trough behind it that we need to keep an eye on though.

Last night was another good night for night flight.  It petered out in the northern portion of the I5 corridor but still decent.  Medford had one of it’s best nights of the season.  So, i’m putting up the I5 radar loops; Medford to Seattle in today’s gallery.

I didn’t find any Willow Flycatchers this weekend but they are definitely filling in as seen HERE. I did come across my first Lazuli Buntings, but they have been here a couple of weeks now; i just can’t get out into the field as often as i like.  HERE is their map.

18 May 2017 – PNW Migration Update

A very good night for flocks flying free.  All alliteration aside, again we had clear skies and gentle winds out of the north.  The upper left corner was cooking green doughnuts last night with a really nice flight across the Strait of Juan de Fuca over to Vancouver Island.

One more Willow Flycatcher was added to the MAP.
