27 March 2017 – PNW Migratio Update

This is way past getting old so lets not discuss it.

Black-headed Grosbeaks in San Diego, Ospreys, Rufus Hummingbirds, and most Swallows are firmly established in the Metro Region.

Elsewhere at the national level we can see the SE and Gulf Coast hopping.  A few storms to dodge here and there but plenty of open air.  Thanks Paul!

20 March 2017 – PNW Migration Update

A very rainy weekend — again.  It cleared up late Saturday night but too late for any birds of significant numbers to move north.

But, last night was clear and there was an accommodating south wind so the birds were on the move.  We’re still at the beginning of the migration so we are not getting “green doughnuts” but we do have some 20+ dBZ returns.

In the Central Valley more Western Kingbirds are being reported as well as Common Yellowthroats.  In the Portland area Violet-green Swallows, Rufus Hummingbirds, Osprey and an increasing number of shorebirds.  I observed over sixty Greater Yellowlegs, a few L.B. Dowitchers and a large flock of peeps (unidentified) on the wing this weekend.

The Central and Mississippi Flyways were also pretty active last night.  National Composite Radar is included thanks to Paul

17 March 2017 – PNW Migration Update

First clear night in a LONG time and winds out of the south = a pretty decent and widespread movement of north bound migrants.  Decent enough that i even put in the loop from Gray’s Harbor (LGX)

Looking at the wind map we can see why there was very little movement up the Atlantic Flyway and some decent flights up the Central Flyway.

A few shorebirds are popping up, swallows are becoming more widely reported including early vanguard Cliff and Northern Rough-wing, and the Snow Goose numbers are way down on Sauvie Island.

15 March 2017 – PNW Migration Update

Well, another night of rain.  The birds are still fighting to get north and picking their way through the gaps and along the edges.  The Hydrometeor sounding is the best way to see this so it is the loop i put in the gallery today.

I also put in a snap of the National Composite from Paul’s archive.  Really, the only activity is in Texas and the Central Valley of CA.  So, we’re not in a full blown race to the north yet — but soon.

 

25 October 2016 – PNW Migration Update

As expected from what we saw yesterday the south winds continued through the night with scattered rain cells.  And, very low levels of migrants passing through.

So lets take a look at the National Composite because there has to be some action going on somewhere.  Looking at the wind map we can see the Central Flyway pretty much shut down and the best conditions are in the Mississippi and southern Atlantic Flyways.

And the radar shows:

20 October 2016 – PNW Migration Update

It’s been a rather crappy week or two for watching radar returns for migrants.  They have been on the move but only visible in the Hydrometeor loops and even then at low densities and opportunistically.

Now it seems KRTX – the Portland area radar is off line!  So, here is a static shot of the National Composite.  The Atlantic Flyway was screaming last night.  And you can see the lack of returns from RTX.  I hope it is just maintenance.

01 September 2016 – PNW Migration Update

Shorebirds continue to move through the area.  Quite a few Solitary Sandpipers are showing up and an unusually high number of Buff-breasted, Baird’s and Semipalmated Sandpipers as well.

But, last night was another low level night for movement.  Winds were mainly out of the east with a drizzle here and there. Check it out:

I threw in the National Composite so you can match the winds to migration density.  Check out the Mississippi Flyway.
