A very rainy weekend — again. It cleared up late Saturday night but too late for any birds of significant numbers to move north.
But, last night was clear and there was an accommodating south wind so the birds were on the move. We’re still at the beginning of the migration so we are not getting “green doughnuts” but we do have some 20+ dBZ returns.
In the Central Valley more Western Kingbirds are being reported as well as Common Yellowthroats. In the Portland area Violet-green Swallows, Rufus Hummingbirds, Osprey and an increasing number of shorebirds. I observed over sixty Greater Yellowlegs, a few L.B. Dowitchers and a large flock of peeps (unidentified) on the wing this weekend.
The Central and Mississippi Flyways were also pretty active last night. National Composite Radar is included thanks to Paul
Well, another night of rain. The birds are still fighting to get north and picking their way through the gaps and along the edges. The Hydrometeor sounding is the best way to see this so it is the loop i put in the gallery today.
I also put in a snap of the National Composite from Paul’s archive. Really, the only activity is in Texas and the Central Valley of CA. So, we’re not in a full blown race to the north yet — but soon.
It’s been a rather crappy week or two for watching radar returns for migrants. They have been on the move but only visible in the Hydrometeor loops and even then at low densities and opportunistically.
Now it seems KRTX – the Portland area radar is off line! So, here is a static shot of the National Composite. The Atlantic Flyway was screaming last night. And you can see the lack of returns from RTX. I hope it is just maintenance.
Migration continues in spite of my absence – i’ve been out birding far afield.
Nighthawks have arrived in Oregon – i saw one two days ago in Diamond and a couple of the members in my party saw a couple more around Malheur NWR. This kind of ends the arrival notifications but birds are still on the move as they settle in and look for summer nesting locations.
Malheur NWR Headquarters is still shut down as well as the access to Benson Boat Landing. Labor Day migrant birders will have to do with the CPR and surrounding environs. Good news is that the refuge staff have let the Blitzen waters flow. A couple of weeks ago the river bed was bone dry at the bridge next to headquarters. This weekend the river was filling the channel and many fields and canals have water in the northern part of the refuge. Hit me up if you want a scouting report from the past couple of weeks at Malheur.
This will be the last post of the spring — see you in the fall!
Light to moderate migration last night. The high pressure ridge we were watching at the end of last week moved north instead of inland. That kept the winds out of the north. Birds are moving through just not at peak densities.
Looks like it was a good weekend to be looking for shorebirds on the north coast – if timed right. Take a look at what my friend Bob scrounged up HERE>
I haven’t caught up with the listserves but Western Tanager, Cassin Vireo, Yellow-breasted Chat and Lazuli Bunting are in. And this morning i heard the flight calls of Swainson’s Thrush overhead; at least a half a dozen.
Nationally birds were dodging some heavy weather but in the breaks and clear air heavy migration was taking place.
