12 October 2015 – PNW Migration Update

Heavy migration last night as the south winds and occasional rain cell that moved through over the weekend abate. The winds are still out of the south but mainly along the coast and to a lesser extent inland.

I did make it up into the Cascades this weekend.  The big lakes and reservoirs were covered in Mergansers, Common Loons, Western and Horned Grebes.  Western Grebes being in the vast majority of divers.  Good numbers of California Gulls as well.  But away from the water — not much was going on that i could detect.

Looking at the wind map one would expect late migrants taking advantage of the northerly flow down the Central Flyway.  The National Composite Radar shows just that.  I have a snap shot of the flight but i encourage the curious to watch the loop where the movement through Kansas and Nebraska is pretty cool.  You can actually see migrant flocks move through from radar station to radar station.

Here is Cameron’s Winds of the Earth loop, and here is Paul’s archived Radar Composite from last night.
