23 March 2017 – PNW Migration Update

I skipped yesterday because this constant rain is getting old and keeping the birds grounded.

Last night started out the same but cleared fairly early, but still, very few migrants took advantage of the clear skies and south wind.  Ah  well, it’s only March.

 

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

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.

16 March 2017 – PNW Migration Update

This is getting old – rain.

It rained most of the night keeping the birds hunkered down.  Early in the morning the rain cells moved through and only a few insomniacs took advantage of the window.

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.

 

14 March 2017 – PNW Migration Update

Birds continue to pick their way north; choosing their place and time between and in the gaps of the storm cells.  I put in the Hydrometeor loop today so it is easier to pick out the birds – look for the brick red biological returns.

Late this morning we see a pretty decent flight up the east valley once the heavier rain moves through.
