20 April 2017 – PNW Migration …..

Rain.  So take a look at a static shot of the national radar composite instead.

Thanks Paul!

18 April 2017 – PNW Migration Update

Crimony. Is it ever going to stop raining?  Thank goodness we have a president that is gutting all of out climate change initiatives and research.

Anyway, we can see some decent movement between the rain cells here in the Metro area.  But if you want to see really dodgy flight behavior take a look at the Aberdeen (ABR) loop i put in the gallery today! And a static shot of the National Composite — lots going on last night.

Western Wood Pewees in San Diego, while up here: more Nashville Warblers, Yellow Warblers, Black-headed Grosbeaks, Warbling Vireos and even a Hermit Warbler.  All pretty much on schedule.  Shorebird migration is underway as well.

14 April 2017 – PNW Migration Update

We had an abbreviated flight last night; lasting from about 8 PM to 2 AM, and it wasn’t particularly widespread.  I’m pretty sure the birds are as sick of the rain as i am but at least it  was spread out and not too heavy.

Big night for the Atlantic and especially the Mississippi Flyways.

San Diego is reporting the first Lazuli Buntings and Western Kingbirds.  We don’t usually get Ash-throated Flycatchers in the Metro area but the Central Valley (CA) is now reporting them.

Locally: Hammond’s Flycatchers, House Wrens, Bullock’s Orioles and Yellow Warblers have now been reported.

12 April 2017 – PNW Migration Update

A solid night of ….. rain.  I’m sure birds are slipping through, we just can’t see them.

So i put in the National Composite (thanks Paul) and the wind map.  A good study today about migration and weather.  Big flight up the Central Flyway,  shut down behind the squall line but advancement up the Atlantic Flyway ahead of the weather.

Central Valley is reporting Bullock’s Orioles, Black-headed Grosbeaks, Purple Martins, House Wrens, Wilson’s, Nashville and Yellow Warblers.  The Yellow and Nashville Warblers have made it to the Metro Area as well as the Purple Martins.

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

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.
