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.

07 April 2017 – PNW Migration Update

A few rain cells had to be dodged last night but the birds were out in front and then came in behind the largest of them.  I didn’t hear of any new arrivals just more of the ones mentioned yesterday.

The real news is the powerful and well organized spring cyclone that will rake the Oregon and Washington coasts with gusts up to 70 mph. The winds will initially be out of the south and maybe some diurnal migrants will take advantage.  HERE is a great write up about the forecast by Cliff Mass.

When you look at the Wind Power Density map you can see two things jump out — the power of the approaching storm and the stream lines out of the south right up the Central Flyway — and indeed that flyway was very active last night; from Brownsville to Minot.

 

27 March 2017 – PNW Migration 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!

After the wettest Feb on record, PDX is knocking on the door of another record in March. Record: 7.89″. Current: 7.00″

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
