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.

11 April 2018 – PNW Migration Update

We’re going to save disk space today – no radar loops.  They’re pretty boring anyway — 10 dBZ with only a few patches up into the 20’s.

Most action was out of Ridgefield and Steigerwald.  Nationally the Central Flyway was the hot spot.  See Paul’s archive for that loop.

But we are getting reports.  In the metro area: Nashville Warblers, Hammond’s Flycatcher (earliest by six days) Vesper and Chipping Sparrows.

And a remarkable House Wren in Clallam County, WA.

Admin. note — i will be off grid until next Wednesday.  See the sidebar for links to stay abreast of this Spring’s migration.

13 April 2017 – PNW Migration Update

Moderate flights between weather.  With a pretty decent exodus from the Sauvie Island WMA/Ridgefield NWR complex.

Speaking of Sauvie Island; Oak Island and the west side units are due to open to public access on Sunday the 16th.  East side units will remain closed until May 1.

A Gray Flycatcher was reported in the Central Valley and Cassin’s Vireo and Evening Grosbeaks in the Metro Area.  I forget if i mentioned it earlier but both Chipping and Vesper Sparrows have also shown up.

Well, it’s raining again.  But, there was a gap during the night and our northbound feathered cohabitants took advantage of the break.

Black-throated Gray Warblers, Orange Crowned Warblers, Caspian Terns, Calliope Hummingbirds, Yellow-headed Blackbirds, Common Yellowtrhoats, Evening Grosbeaks and Chipping Sparrows — now being reported in or around the 45th parallel.  It happens like that; in a mad rush.

11 April 2016 – PNW Migration Update

Since i take the weekends off from this project i’m not sure what the birds were up to Friday and Saturday night.

But i do know what they were doing in the field.  Duck numbers are down, Snow Geese are gone but there are plenty of Cacklers still around.  A few more shorebirds are around.  The snipe are winnowing, Sooty Grouse are booming and a few cranes are practicing their mating dance.  Common Yellowthoats are firmly entrenched. Chipping Sparrows are dotting the landscape.  And northbound Blue-winged Teal are popping up in their usual low density numbers but to the delight of those who happen upon this strikingly beautiful bird.

On the listserves; MacGillivray’s Warbler, Black-headed Grosbeak, and Western Tanager have made it to the Willamette Valley.

Outliers of Hammond’s Flycatcher, Swainson’s Thrush and Western Wood Pewee have been reported as well.  Treat those as you will.

Last night we had light to moderate migration across the region so i am going to conserve cloud space and only put in the RTX loop today.  LGX and ATX both had approximately the same density.

08 April 2016 – PNW Migration Update

Unfavorable but light winds did not deter migrating birds.  Most of the action was up in the Seattle area with a very strong flight across the Strait of Juan de Fuca.  Also, a significant movement along the coast.

Sora, Chipping Sparrow, Black-headed Grosbeak and Western Wood Pewee have now been reported in the northern Willamette Valley.

05 April 2016 – PNW Migration Update

Too much to do on the weekends – but the nocturnal flights during the good weather were in the moderate to heavy range.  Alas, i didn’t archive any loops.

Today, with cross winds, the flight was light last night.

Take a look at the Wind Map  and you can see why the Central Flyway had most of the action.

Common Yellowthroat, Barn Swallow, Northern Rough-winged Swallow, Cliff Swallow, Caspian Tern, Chipping Sparrow, Black-throated Gray Warbler, American White Pelican — all now being reported in good numbers in the Portland/Vancouver Basin.

Early arrivals in Oregon include: Vaux’s Swift, Nashville Warbler, Pacific-slope Flycatcher.

As well as arrivals there are also departures,  Tundra Swan, Snow Goose, Canvasback, Ruddy Duck, Ring-necked Duck  — all significantly down in numbers
