Migration is still concentrating in the east counties but picking up in the west.
It looks like we have a well organized low coming in from the Gulf of Alaska. The leading edge will put up stiff southerly winds that will probably keep all but the most hardy or determined birds grounded for the next day or two. But the back side of the system, as it passes through, should be golden. Depending on the strength, it may even pull in some vagrants.
Meh, we still have not had any major influx of migrants. We are getting reports of arriving ducks (they all look just brown to me this time of year); Shovelers, GW Teal, and Pintails. So migrants are on the move — just not spectacular masses of them – yet.
The local radar image looks just like yesterday so, instead, lets look at the national composite, archived by Paul, and cherry pick – Duluth! I added a shot of the Winds of the Earth to show the north winds that are facilitating the flight down the Mississippi Flyway.
Pretty much the same as yesterday – movement, but moderately so.
It’s always a good thing to keep up with what’s going on up north at the BC Tatlayoko Bird Observatory. They get a few birds that move over to the Central Flyway but many more that are headed our way. So, for instance, they will see the Fox and Golden-crowned Sparrows before we do and it is nice to know what’s in the pipeline.
So, i said i would put up a migration update the rest of this season if anything extraordinary came up. While the RTX (Portland) radar was a solid green (heavy migration) doughnut last night, take a look at what’s going on in Gray’s Harbor!
Right around 09:00 UTC (02:00 AM PDT) the returns start to go into the yellow range. That is EXTREME! This only happens one or two times a season, if at all. So, if you want to see tens of thousands, and maybe hundreds of thousands, of shore birds today — head on over, it will probably be quite the show.

Also, i have updated the migrant watch list. Using eBird data i added the first reported date for those little fluff balls that are on the watch list — except for those that also winter here like Yellow-rumped Warbler.
Chilly north winds kept migration to a minimum last night in the metro area.
However a strong river of southerly winds crammed a boat load of birds up the Central and Mississippi Flyways. I have static images of the Winds Aloft and the National Composite Radar in today’s gallery. But, head on over to Cameron’s and Paul’s sites to get the dynamic view of this marvelous show.
Well, the Western Wood Pewee and Willow Flycatcher have been ticked. The former in Clackamas County and the latter in Clark. So that wraps up this season – well, except for the Common Nighthawk, and it is not detected every year. With the NAMC this weekend and a scheduled trip to Malheur NWR next week, the only posts i’ll be putting up this season will be if something exceptional takes place. There’s still plenty of birds to move through so use the links on the side bar to keep in the loop.
Moderate levels of migration last night trickling off as a little rain started moving through and putting a damper on continued flight. Could be a good day to check your favorite patch in the Metro area. There could be a concentration of birds from the pile up that the rain can cause.
No word on the Western Wood Pewee or Willow Flycatcher yet.
Moderate to heavy migration took place all weekend. New arrivals were everywhere out in the field. I still haven’t seen any reports for Western Wood Pewee or Willow Flycatcher. Good numbers of Swainson’s Thrush were out and tonight, in a clear, full moon sky, i heard about a half a dozen nocturnal flight calls in the two minutes i spent listening.
The Atlantic Flyway finally got some love last night. For a full report head over to Tom’s recap.
No tail winds, but no significant deterrents as well. There was a moderate amount of movement last night and even heavy in patches.
We’re still waiting on reports for Willow Flycatcher and Western Wood Pewee to close out this season. But with a Blue Grosbeak and a White Wagtail in the area i doubt many will be paying close attention.
Winds are shifting to out of the north and there are cells of showers moving through the area. No surprise that the migration last night was moderate at best.
A Swainson’s Thrush was reportedly heard in the area and a Western Tanager was seen in the Corvallis area. Below the gallery is an update list of the migrant watch. We are down to six species and two of those (Gray Flycatcher and Red-eyed Vireo) are not detected every year. The Red-eyed Vireo has set up a breeding range locally around the mouth of the Sandy River so it will eventually be reported.
Update: an Olive-sided Flycatcher was reported 4/27.
