Tweeters,

Cliff Mass in his 6 March 2020 weather blog documents substantial numbers of birds migrating north from Portland OR on Wednesday night (4 March). Further, he explains the weather pattern that night was conducive for migration, giving the "birdies" as he calls them, a tailwind.

Pretty cool stuff!
