Decent movement through the night in the Metro area, but much more subdued along the coast and the Puget Sound,; so i’m not including those today.
No news on any new arrivals that i saw. We’re still debating the Hermit/Swainson’s issue. Of the arrivals already mentioned; many are increasing in numbers, so they’re solid.
Nationally: a weird weather pattern shut down the Central Flyway but allowed migrants into southern Texas — maybe a classic Fallout situation. The Mississippi and Atlantic Flyways were active though. Not MEGA but still a lot of movement.
Western Wood Pewees and Bullock’s Orioles are now being reported in Oregon. San Diego has it’s first report of Swainson’s Thrush. No reports of Willow Flycatcher yet.
As a guide to spring migration phenology I have a page in the top banner with a calendar. And at the bottom of that page is a link to a very good narrative written by David Irons. HERE is a direct link to his work, and it is really worth the time.
Pretty solid movement across the region last night. The high pressure ridge is weakening and winds, while not favorable were very light. The Atlantic Flyway was really lit up last night, probably it’s best this season. Well, all Flyways were very active, the Atlantic just stood out to me. Lots in the gallery today.
In the Pacific Northwest (PNW) we’re throwing a bit of a headwind and scattered showers at the migrants. If they are content with where they are for the moment, they’re not going to get up and waste energy fighting that. So, they didn’t.
There’s always somebody on the move, but it was at very low densities. New arrivals being reported include; Hermit Warbler, MacGillivray’s Warbler, Yellow Warbler and increasing numbers of Warbling Vireo, Vaux’s Swift, Lazuli Bunting, and Black-headed Grosbeak.
Since our flight was puny, we’ll look at the National scene. Mississippi and Central Flyways were rocking and a glance at the Winds of the Earth plot tells the story.
