20 April 2017 – PNW Migration …..

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

Thanks Paul!

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.

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.

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

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.
