04 May 2018 – PNW Migration Update

Decent movement through the night in the Metro area, but much more subdued along the coast and the Puget Sound,; so i’m not including those today.

No news on any new arrivals that i saw.  We’re still debating the Hermit/Swainson’s issue.  Of the arrivals already mentioned; many are increasing in numbers, so they’re solid.

Nationally: a weird weather pattern shut down the Central Flyway but allowed migrants into southern Texas — maybe a classic Fallout situation.  The Mississippi and Atlantic Flyways were active though.  Not MEGA but still a lot of movement.

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+.

15 September 2017 – PNW Migration Update

Another solid night of migration with returns into the 20+ dBZ range.  More noticeable migrants pile out of the Nisqually Basin and into the Vancouver Basin.

Reports of more Cackling Geese, first Hermit Thrushes on the valley floor, Fox and Golden Crowned Sparrows as well.  We are well into the season and trips into the field this weekend should yield plenty of FOS birds.  The Chapman School Vaux’s Swifts are still piling into the chimney by the thousands each night.

Barn Swallows continue to roost and fly-out at dawn along the Willamette River in Yamhill County.  The evening roost flight was particularly dense last night.

06 September 2016 – PNW Migration Update

While there was light movement last night most of it was obscured by clouds.  So we’ll take a look at the Hydrometeor Classification Loop so we can pick out the biological returns. (brick reddish signal)

On the ground; reports for Fox, Golden-crowned and Lincoln Sparrows, Hermit and Varied Thrushes, and the continued passage of shorebirds.  So far it’s been an unusual season — lots of birds moving through but at a low, but consistent pace.
