We’re moving deeper into the migrant season but it still seems quiet in the field. I have missed the last couple of weekends so i am anxiously counting the days until the next. The listserves aren’t lit up with arrivals either.
Anyway, birds are on the move; locally and nationally where conditions are favorable:
Shorebird migration is apparent but sightings are dictated by water levels. We may have even passed the peak according to some observations and comments — seems pretty early to me. But then; the first reports of Greater White-fronted Geese are in and they’re a couple of weeks early.

The wind map is from a different perspective — more northerly. That’s where the birds are coming from for the most part and it shows why competitive listers head to the Aleutians and Western Alaska this time of the year hoping for some Siberian to be blown off course.
If you have been out in the field or read any of the regional listservs then you are aware that the shorebirds have been moving through for a few weeks now; since late July. Seems early to me but i am getting old and forget stuff.
This post is just a teaser really because i am going off grid for a week or so but i thought i would get the fall inaugural post up; if for no other reason than to incite some to go find a patch of mud and locate that Asian stint.
Anyway, movement is detectable but still pretty low density as can be seen in last nights radar:
Nighthawks have arrived in Oregon. HERE is the map – not too impressive and these are the first arrivals to be sure. But — This kind of ends the arrival notifications for the season; birds are still on the move however; they are settling in and looking for summer nesting locations; filling in the gaps.
It is the beginning of a long weekend and after that i will be far afield and unplugged. There are a couple of days next week i will be checking in on migration; if i see anything pronounced i’ll post it — but i doubt that will happen.
Blue-winged Teal have been popping up here and there in the remaining wetlands throughout the region HERE This is a spring ritual as they are late migrants and occasional breeders that winter to our south. They are such magnificent birds it is always a treat to come across them.
The Mississippi Flyway is still electric when the conditions are favorable so we’ll take one last look at the National Composite Radar in today’s gallery as well.
The RTX loop from last night shows what migration looks like as it begins to wind down. Pretty decent conditions and diminished movement. But there are still birds in the pipeline as the radar from Medford (MAX) shows.
Another sign that the end is nigh — predawn Violet-green Swallows twittering (not Trump’s type of twittering) in the dark sky above.
Today’s wind map shows two things — the first is the advance of another high ridge; could get windy out of the north as it advances. The second is the pressure differential between the east side and west side of the northern Cascades. Hey Seattle — that’s where your winds are coming from. Check out Cliff’s excellent ‘explainer’ on his blog today.
The migrants continue to fill the airways at night. At this time it is just filling in – the major waves have moved through or are settling down and establishing nesting territories. The last of the wintering ducks are down to onesies and twosies and the male breeding ducks are showing signs of molting into eclipse. There remains legs in the migration but it is beginning to wind down.
Willow Flycatchers are still under represented as seen HERE.
