As expected from what we saw yesterday the south winds continued through the night with scattered rain cells. And, very low levels of migrants passing through.
So lets take a look at the National Composite because there has to be some action going on somewhere. Looking at the wind map we can see the Central Flyway pretty much shut down and the best conditions are in the Mississippi and southern Atlantic Flyways.
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.
Decent but not solid ‘green doughnut” crazy migration across the Pacific Northwest. Our winds aloft are still out of the north as a high pressure ridge moves in.
Didn’t check the listserves for new arrivals, but i did check in on the National Radar Composite. Check the wind map — check the migration pattern. Sparse movement up the Atlantic Flyway and just jamming it up the Mississippi and Central Flyways.
Heavy rains, as the low pressure trough moved through, kept birds grounded for the most part. There was light to moderate movement as it subsided – most likely the strong fliers like waterfowl. The best movement was along the coast; probably because the rain moved past earlier in the day. So, i put in the LGX (Gray’s Harbor) loop today.
The high pressure ridge is slipping to the south so we will probably get onshore easterly winds instead of the northerly winds predicted yesterday. It should still be nice weather to get out birding this weekend.
On the national level; except for the SE where there is some weather, the board was lit up from the Atlantic to the Great Plains. Check out the wind map and you can see why. Just for fun we’ll watch the birds cross the Straits of Florida today – Key West is in the gallery.
