Yesterday in the narrative we had twelve migrants yet to be reported in the Northern Willamette Valley. To day we are left with eight. Yesterday there were reports of Yellow-breasted Chat, Yellow Warbler, Hammond’s Flycatcher, Black-headed Grosbeak. To our south in the Shasta area a Common Nighthawk was reported.
Great conditions, clear skies and a nice tail wind – BOOM! Heavy migration last night, all night. The loop says it all.
Take a look at the wind map and you can predict the scenario. Northeast – shut down. Mississippi and Central – pile up in Texas and continuation behind the weather. Pacific – open for business.
