Continuing north winds probably hampered migration a bit, but not completely. There was a nice push of birds in east Clark County probably originating from Steigerwald.
Looks like this ridge of high pressure may stick around for a while. That will bring some much needed relief from the rain, but as long as it hangs in the Gulf of Alaska we will continue get these north winds aloft.
One glance at the Winds of the Earth and you can pretty much guess the Central Flyway and possibly the southern part of the Atlantic Flyway is set up for decent migrating conditions.
Black-headed Grosbeaks have made it to San Diego, Common Yellow-throat and Northern Rough-winged Swallows to the Willamette Valley.
As a high pressure ridge builds in the gulf of Alaska north winds are found across the region. That put a damper on an otherwise decent night for migration.
We saw a very light movement last night. but since i last checked in a number of migrants have made their way into the Pacific Flyway pipeline: Yellow Warbler, Common Yellowthroat, and Brewer’s Sparrow.

HERE is a great article by Kenn Kaufman on obligate migrants and facultative migrants that may be of interest to folks. It is focused on his patch back in Ohio but it pertains to all migrants, even those that use the Pacific Flyway.
Light migration last night with one pretty good pulse out in SW Washington County in the Hagg Lake area. Which is kind of curious.
Because the movement was light and there were isolated rain cells moving through today i put in both the Reflectivity and the Hydrometeor loops. It is an informative juxtaposition as it gives us a chance to train our eye when interpreting the returns on the Reflectivity loops.
No new birds to report today. Well, Bell’s Sparrows and Hooded Orioles are up into the Central Valley but these are not going any further so i’ll just leave these out of the mix.
