01 May 2017 – PNW Migration Update

And then there were birds!

Big weekend for the Pacific Flyway.  I have the Friday/Saturday loop, but left in on another computer; it looks pretty much like today’s Sunday/Monday loop.  Saturday/Sunday was muted by weather.

More arrivals: Western Kingbird, Western Tanager, Lazuli Bunting, Black-headed and Evening Grosbeak,  Bullock’s Oriole, Sora, Empids, Wilson’s and Nashville Warbler, and Cassin’s and Warbling Vireo.  All five Swallows have now been reported as well as Vaux’s Swift. Big numbers of the early migrants as well, House Wren, Yellow-rumped and Orange-crowned Warblers.  Pelicans and Purple Martins are more widely reported on Sauvie Island.

Many birds are already on, or building, nests and even some fledglings are being seen.  I even saw a Green-winged Teal male transitioning to eclipse plumage this weekend.

I haven’t seen or heard a Ruby-crowned Kinglet in a while; Golden-crowned Sparrow numbers are down, Migrant Fox and Lincoln’s Sparrows are pretty much off the radar.  Water Fowl numbers are dropping as well.

Let’s see, what’s left?  From memory (so don’t hold me to this) Swainson’s Thrush,  Yellow Warbler, Western Wood Pewee, Red-eyed Vireo (rare but annual nesting resident) Willow Flycatcher and ……?

I really should change the title of these posts.  The Pacific Northwest is a big place and i don’t keep tabs of much outside of the Portland/Vancouver Basin and the Willamette Valley.  So, for example, when the Puffins return to the coast, i’ll miss it by a couple of weeks to a month, they’re back, but i’m not sure of when they arrived.

30 March 2017 – PNW Migration Update

We can see a few birds on the move darting and weaving between rain cells last night.  At least it’s something!

New arrivals being reported: Vaux’s Swifts, Common Yellowthroat, and now all five swallows.

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

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.

10 March 2017 – PNW Migration Update

Well,  The birds have been picking their way north for a few weeks now, but because of the nearly constant rain it has been damned hard to pick them out of the radar noise.  Even the HC was not reliably designating biological returns.

Last night however, once the rain moved through, we got a decent migration signature.  On today’s loop, wait for the rain to pass and you will see the flight — up into the 20 dBZ range.

Tree and Violet-green Swallows as well as Turkey Vultures have made it to the Portland area.  Even Barn Swallows are being reported in Clallam County in Washington.  Western Kingbirds are in the Central Valley in California as well.  Waterfowl numbers are down a bit too.

21 March 2016 – PNW Migration Update

Nothing to see the past couple of days because of the rain.  There were a few birds moving in between the rain cells but not many.

San Diego:
Western Kingbirds are now being reported

Central Valley:
Warbling Vireo

Willamette Valley:
Reports of increasing Violet-green, first Barn and Cliff Swallows, and more Orange-crowned Warblers

Let’s take a look at a snap shot of the national composite radar today.  The archived loop, as always, can be found on Paul’s Site.  The big action was up the Central and Mississippi Flyways:
