08 May 2017 – PNW Migration Update

RTX is back on line!  Whew; that can take over a week sometimes.  Came back on line late Friday.

Migration is entering it’s peak phase.  Most, but not all vanguards have arrived and are being followed by the trailing hoards.

Wilson’s Warblers were over the top conspicuous when i was in the field Saturday.  A few more reports of Swainson’s Thrush and i definitely heard my first Western Wood Pewee on Sunday and a handful of other reports are up on eBird.  Lazuli Buntings are filling in.  Bullock’s Orioles have made it to the Seattle area. No sign of Willow Flycatchers yet.

The Atlantic Flyway was the only flyway that was underwhelming in regard to it’s capacity.  The rest look to be at full tilt.

I threw in the Seattle (ATX) loop today for good measure:

21 April 2017 – PNW Migration Update

Well, a relatively clear night with light winds out of the south and you would expect a surge of migrant activity.  But it was really rather muted.  We did get a smattering of 20+ dBZ returns; i just expected a much deeper and widespread response.

Arrivals, or increased reporting: Vaux’s Swifts and Wilson Warblers.

Two notes — another well organized low is headed our way (read, more rain) and there was a pretty interesting flight path down the Columbia and out to the coast that can be seen in last night’s loop; i don’t recall seeing that before.

12 April 2017 – PNW Migration Update

A solid night of ….. rain.  I’m sure birds are slipping through, we just can’t see them.

So i put in the National Composite (thanks Paul) and the wind map.  A good study today about migration and weather.  Big flight up the Central Flyway,  shut down behind the squall line but advancement up the Atlantic Flyway ahead of the weather.

Central Valley is reporting Bullock’s Orioles, Black-headed Grosbeaks, Purple Martins, House Wrens, Wilson’s, Nashville and Yellow Warblers.  The Yellow and Nashville Warblers have made it to the Metro Area as well as the Purple Martins.

18 April 2016 – PNW Migration Update

It’s been a non-stop bird fest throughout the weekend.  We’ve had heavy migration with more new arrivals being reported in the Region: Vaux’s Swift, Nashville Warbler, Yellow Warbler, Wilson’s Warbler, Western Tanager — all come to mind and i’m probably forgetting a few.

Notable departures: Sandhill Cranes are WAY down on Sauvie Island, it’s hard to come by any more than a few straggling ducks except residents and Green-winged Teal.  I haven’t seen a Pintail in a week or so.  Junco’s are back up in the hills and Varied Thrush have disappeared as well.

Full regional coverage today.  The weekend looked about the same.
