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!

21 March 2017 – PNW Migration Update

Rain, heavy at times and easing up through the night.  Sigh.

There was a nice south wind, so anxious birds braved the weather and picked their way north.  Not in great numbers but fairly widespread as the weather would allow.  It’s tough to pick them out between the rain cells so we have the Hydrometeor loop today to aide in finding the birds; a little like finding Waldo.

American White Pelicans have been reported in the region, a few more Western Kingbirds and Osprey as well.  Ruby-crowned Kinglets are starting to sing.  It’s a wonderful song and we only get a small window in early spring to hear it before they clear the area as they head north to the breeding grounds.

Pacific Slope Flycatcher reported in the Central Valley is a first arrival.

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

13 March 2017 – PNW Migration Update

As suspected (but not verified because of the terrible weather recently) migration is in full tilt.  Mostly, waterfowl are on the move it seems.  I’m not seeing any reports of widespread passerine movement.  There has been reports of Violet-green Swallows and a few reports of vanguard Osprey.  Last night’s movement was aided by a SE wind.

17 March 2016 – PNW Migration Update

Well, after a week of rain we finally got a clear night.  Birds took flight but in very moderate numbers.  There were a few patches where the density reached the 20 dBZ level but not many.  It’s still early.

In the region: first Violet-green Swallows, Turkey Vultures are increasing, Black-bellied Plovers have been seen and the first reports of returning Osprey.

In the San Diego area the Swainson’s Hawks are staging in Anzo Borego, and the first Pacific Slope Flycatchers are being reported.

Barn Swallows have made it to the Central Valley.

04 March 2016 – PNW Migration Update

A very interesting night.  We had some decent southerly winds aloft and only isolated cells of disturbance.

There was widespread low level migration across the region.  There were also two interesting heavy returns past the 20 dBZ level.  The first arising from the Sauvie Island/Ridgefield area.  OK, those are waterfowl.

But the second is that same odd return originating from Linn and Marion Counties east of I5 and heading straight for Mt. Hood.  We saw this earlier this season.  I pulled up the HC loop and we can see a DS (Dry Snow) return with the same time stamp and trajectory.  So i am really not sure what is going on here.

Anyway, nice to have some clear air and see our feathered friends heading north.  First Ospreys are being reported in the metro region.

Speaking of friends,  David Irons just started a blog which you can find HERE.  David is one of the best birders on the planet and i am looking forward to seeing what he does with this.  And David, if you come across this post — get an RSS link so i can get your posts to show up in my reader; much easier for me to follow along without having to check in every now and then.
