04 May 2018 – PNW Migration Update

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.

03 May 2018 – PNW Migration Update

Another solid night of migration across the region.

I’ll leave out the National scene but it was rocking in the Southern portions of the Central and Mississippi Flyways.  Buoyed by some sincerely favorable winds.

Elegant Terns have shown up along the Central Coast along with the first report of an Olive-sided Flycatcher.

 

02 May 2018 – PNW Migration Update

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.

 

30 April 2018 – PNW Migration Update

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.

20 april 2018 – PNW Migration Update

Pretty decent movement up the valley last night.  Not “Green Doughnut”, but close.

Nationally the Central Flyway was the hot spot.  Looking at the wind map you can see why.

06 April 2018 – PNW Migration Update

Common Yellowthroat, MacGillivray’s Warbler and more Bullock’s Orioles in the San Diego area.

Cassin’s Vireos and Wilson’s Warblers have made it to Oregon.

Lots of rain in last night’s radar and not much detectable movement, so we’ll check in on the National migration. (Remember you can always go to Paul’s site to get the loop)

The heavy weather system has moved on and birds are moving through the Ohio Valley and up the Central Flyway.

04 April 2018 – PNW Migration Update

Purple Martin have made it to the Metro Area.  As well some shorebird movement with Black-bellied Plovers and Lesser Yellowlegs being reported.

Black-headed Grosbeak, Wilson’s and Nashville Warblers now being reported in San Diego area — they’re on their way!

Messy radar images from last night due to cloud cover and patches of rain, so we’ll check in on the National Scene.

A large storm system from Texas to New England restricted migration to the SE much like the last time we checked in on the 27th.  Note the lift off from Cuba as birds cross the Straits to the Keys.
