19 March 2018 – PNW Migration Update

There is continued light movement up the valley. Probably waterfowl re-positioning.

There has been really nothing to report in the new arrivals, but on the “it’s just around the corner” front:

Increasing: Rufous Hummingbirds, Turkey Vultures and Ospreys, Tree and Violet-green Swallows.

Bushtit flocks are breaking up and singlets and doubles are now being seen.

Ruby-crowned Kinglets can now be heard singing.  This is a special time as they will soon be gone and their’s is one of the most glorious songs.

Waterfowl numbers are shrinking as well.

We’ll save some disk space and not post a radar loop today — it’s just sub 10 dBZ blue.

Well here we are again!

So, vanguard Turkey Vultures and Ospreys have been reported in the valley.

Rufus Hummingbirds along the south coast in Coos County.

Tree and Violet Green Swallows are just showing up throughout the area.

Robins are singing pre-dawn and Starlings are foreshadowing the arrival of Western Wood Pewees by imitating them.

Down in Anza-Borrego, “The Borrego Valley Hawkwatch has begun. So far over 150 Swainson’s Hawks have migrated through the region”

And this morning i heard Greater White-fronted Geese headed north overhead.

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.
