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.

Good News!  KRTX is back on line!

Last night we had moderate amounts of migrants in the skies from Vancouver Island and down the I5 corridor.  Winds were light and out of the west.  Not too big of a problem.

12 October 2016 – PNW Migration Update

A rather significant drop off in activity last night.  Perhaps the last two nights unleashed the majority of the pipeline.  Activity was down in the Seattle area as well.

Looks like a pretty significant system is spinning up in the Gulf of Alaska and there is an “Atmospheric River” headed in on the Jet Stream.  So it should be a very wet and stormy weekend putting a damper on further migrants and the strong fliers will be somewhat obscured by clouds.

28 September 2016 – PNW Migration Update

Back from a wee vacation.  Only one birding stop.

Last night saw heavy movement along the I5 corridor from the Canadian border south.  In the Metro area the east counties had the bulk of the movement.  Lots of divers and errant ducks being reported from the high Cascade Lakes.  I haven’t had time to catch up on the listservs to see what has been trickling in but i did see large skeins of Cackling Geese in the Portland/Vancouver Basin when passing through.  The waterfowl will be making up the bulk of the migrants from here on out.

The Barn Swallow roost is still putting on a dawn show down in Yamhill and Marion Counties along the Willamette River.

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.

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.
