30 May 2014 PNW Migration Update

This is the last update for the season.  With a bit of luck i’ll be back in the fall.

And we close with a stream of feathers in the sky.

28 May 2014 PNW Migration Update

Less than ideal conditions, but nothing extreme.  A light westerly wind and a few rain cells to dodge – that’s about it.  So the laggards continue to lay a line north.  Densities are dropping as we are on the last legs of the journey.

27 May 2014 PNW Migration Update

Winds are light and out of the west — no big deal.  Migrants continue to flow north and are now looking to fill in the remaining nesting sites.  “FOS” is a term of the past on the listserves.  In eastern Oregon a number of expected vagrants are taking up bandwidth as birders flock to Malheur NWR as surely as Buffleheads fly to Manitoba.

This will be the last week for updates this season — unless something mega turns up in the region.

22 May 2014 PNW Migration Update

Migration in the region last night was a bit reduced from yesterday.  It could be the north winds were slightly stronger and it could be we are running out of birds.  Probably a little of both.  You can see the intensity dropping across the country.  With a second report of Nighthawks it’s pretty much what you would expect.

Next migration update is planned for Tuesday 27 May. I’m taking off for a long weekend.

21 May 2014 PNW Migration Update

As the high pressure ridge moves ashore winds are out of the north.  Along the coast they are quite stiff and probably accounts for the paucity of coastal returns on the Gray’s Harbor (KLGX) radar last night.  But inland, the winds are light and the I5 corridor was lit up as the flight north continues.

20 May 2014 PNW Migration Update

Birds are still moving north.  Winds, with a northerly predilection, are exceedingly light, and pose no real barrier.  Migration season is getting a little long in the tooth here.  It’s not over by any means.  There’s still thousands of laggards to move through, but most of the vanguards have passed through or are settling down. Let’s take a look at the radar and marvel at the wonder of it all.

15 May 2014 PNW Migration Update

As the ridge slides off to the east and a new low begins to move in – there be tail winds.  And the birds are taking full advantage of the opportunity.  “Green Doughnuts” all around.  The Pacific Flyway is lit up from San Diego to Seattle.  If you only look at one radar loop today make it Gray’s Harbor (KLGX) and watch a large, organize flock move up out of Oregon, move along the coast and head out to sea bound for Vancouver Island or possibly even Alaska.

Seattle (KATX) is back on line.

14 May 2014 PNW Migration Update

Light variable winds, clear skies and a biological demand to head north.  That’s a great stage for the drama of migration to unfold.  Sit back, relax and enjoy the show.  With the full moon it’s a great time to do some moon watching.

(KATX – Seattle radar is still off line.)

13 May 2014 PNW Migration Update

The high pressure ridge remains in place.  The winds are light and a bit variable.  Birds are seriously on the move.  Maybe this push will bring those Willow Flies.

KATX is still down: “Message Date:  May 12 2014 14:29:23
THE CAMANO ISLAND RADAR KATX IS EXPECTED TO REMAIN OUT OF SERVICE THROUGH MOST OF TUESDAY. PARTS ARE ON ORDER AND ARE EXPECTED TO ARRIVE TUESDAY.”

We’ll look at Medford (KMAX) in today’s loops.  It’s jamming again.

Today I’m putting the wind map from Earth and a screen grab from the National Composite in the gallery view along with the weather maps. Migration and weather explained in just a couple of pictures. Well, not explained. Perhaps illustrated is a better word.

12 May PNW Migration Update

The high pressure ridge proved a bit more tenacious than i had anticipated.  I took a quick peak at the radar on Sunday morning.  Migration was a happening event at moderate to heavy levels across the region.  And last night, even with less than ideal wind conditions, birds were heavily on the move again.

The radar in Seattle (KATX) is down.  The operators didn’t leave a message on the NOAA hot line so i’m not sure of the future status.  So, we’ll take a look to the south today and put up a loop for Medford (KMAX).  Mainly because the heavy migration through there last night was about as good as it gets in that area.  Yea!  more birds on the way.
