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.

07 April 2016 – PNW Migration Update

Interesting night.  It starts off with low to moderate flight but builds to a heavy flight around midnight onward.  We can see this on the RTX (Portland) and LGX (Gray’s Harbor) radars.  So i suspect these are not departures but arrivals.

In the news; MacGillivray’s Warbler, and Hammond’s Flycatcher have been reported in the Portland/Vancouver Basin.

And another pitch for Cornell’s Birdcast, a weekly guide to regional migration forecasts.

Here are last night’s radar loops:
