30 April 2018 – PNW Migration Update

In the Pacific Northwest (PNW) we’re throwing a bit of a headwind and scattered showers at the migrants.  If they are content with where they are for the moment, they’re not going to get up and waste energy fighting that.  So, they didn’t.

There’s always somebody on the move, but it was at very low densities.  New arrivals being reported include; Hermit Warbler, MacGillivray’s Warbler, Yellow Warbler and increasing numbers of Warbling Vireo, Vaux’s Swift, Lazuli Bunting, and Black-headed Grosbeak.

Since our flight was puny, we’ll look at the National scene.  Mississippi and Central Flyways were rocking and a glance at the Winds of the Earth plot tells the story.

25 April 2018 – PNW Migration Update

Lot’s of activity last night.

Western Tanager, Warbling Vireo, Black-headed Grosbeak, Vaux’s Swift and Lazuli Bunting;  all being reported.  Some in increasing numbers, some vanguards.

23 April 2018 – PNW Migration Update

House Wrens, Western Tanagers, Brown-headed Cowbirds, American Biterns, scads of shorebirds (usual migrants), more Nashville and Black-throated Gray Warblers, Gray Flycatchers (east side).  It get to be hard to catch up, oh and another Hermit/Swainson’s Thrush debate.

Pretty decent movement last night.  Again, not “Green Doughnut” great but widespread at 20 dBZ+.

Pretty decent movement up the valley last night.  Not “Green Doughnut”, but close.

Nationally the Central Flyway was the hot spot.  Looking at the wind map you can see why.

19 April 2018 – PNW Migration Update

Pretty nice conditions but a rather muted night for this time of year.  We had patches up into the 20+ dBZ levels most notable up around Nisqually  NWR.  The coast was much more active with pretty solid 20+ dBZ returns.

New migrants in the area: Grasshopper and Chipping Sparrows.

18 April 2018 – PNW Migration Update

There was decent movement across the region with a traceable pulse up the Willamette Valley.  The coast had a nice movement of birds as well.

Outside of an early movement of Greater White-fronted Geese, no new news about recent arrivals outside of the perennial Swainson’s/Hermit Thrush debate. NO Swainson’s Thrush before May without incontrovertible documentation!

 

17 April 2018 – PNW Migration Update

OK, there is just too much to get through, and i’ve been off grid for only four days.

I’m probably going to miss something; in the Metro area new arrivals are:

Wilson’s Warbler, Cassin’s Vireo and Hammond’s Flycatcher.

In Oregon; Western Kingbirds, Black-headed Grosbeak, House Wren and Bullock’s Oriole.

Not much to see on last night’s radar, and i am behind in other areas, so that’s it for today.
