18 April 2017 – PNW Migration Update

Crimony. Is it ever going to stop raining?  Thank goodness we have a president that is gutting all of out climate change initiatives and research.

Anyway, we can see some decent movement between the rain cells here in the Metro area.  But if you want to see really dodgy flight behavior take a look at the Aberdeen (ABR) loop i put in the gallery today! And a static shot of the National Composite — lots going on last night.

Western Wood Pewees in San Diego, while up here: more Nashville Warblers, Yellow Warblers, Black-headed Grosbeaks, Warbling Vireos and even a Hermit Warbler.  All pretty much on schedule.  Shorebird migration is underway as well.

14 April 2017 – PNW Migration Update

We had an abbreviated flight last night; lasting from about 8 PM to 2 AM, and it wasn’t particularly widespread.  I’m pretty sure the birds are as sick of the rain as i am but at least it  was spread out and not too heavy.

Big night for the Atlantic and especially the Mississippi Flyways.

San Diego is reporting the first Lazuli Buntings and Western Kingbirds.  We don’t usually get Ash-throated Flycatchers in the Metro area but the Central Valley (CA) is now reporting them.

Locally: Hammond’s Flycatchers, House Wrens, Bullock’s Orioles and Yellow Warblers have now been reported.

12 April 2017 – PNW Migration Update

A solid night of ….. rain.  I’m sure birds are slipping through, we just can’t see them.

So i put in the National Composite (thanks Paul) and the wind map.  A good study today about migration and weather.  Big flight up the Central Flyway,  shut down behind the squall line but advancement up the Atlantic Flyway ahead of the weather.

Central Valley is reporting Bullock’s Orioles, Black-headed Grosbeaks, Purple Martins, House Wrens, Wilson’s, Nashville and Yellow Warblers.  The Yellow and Nashville Warblers have made it to the Metro Area as well as the Purple Martins.

05 May 20160- PNW Migration Update

We’re in between weather systems and the winds are light but out of the north.  Obviously it put a bit of a damper on northbound flight as the migration last night was moderate at best.

Western Kingbird, Cassin’s Vireo, Hermit and Yellow Warblers, and Lazuli Bunting – first reports from the general Metro area.

18 April 2016 – PNW Migration Update

It’s been a non-stop bird fest throughout the weekend.  We’ve had heavy migration with more new arrivals being reported in the Region: Vaux’s Swift, Nashville Warbler, Yellow Warbler, Wilson’s Warbler, Western Tanager — all come to mind and i’m probably forgetting a few.

Notable departures: Sandhill Cranes are WAY down on Sauvie Island, it’s hard to come by any more than a few straggling ducks except residents and Green-winged Teal.  I haven’t seen a Pintail in a week or so.  Junco’s are back up in the hills and Varied Thrush have disappeared as well.

Full regional coverage today.  The weekend looked about the same.

28 March 2016 – PNW Migration Updare

As a high pressure ridge builds in the gulf of Alaska north winds are found across the region.  That put a damper on an otherwise decent night for migration.

We saw a very light movement last night.  but since i last checked in a number of migrants have made their way into the Pacific Flyway pipeline: Yellow Warbler, Common Yellowthroat, and Brewer’s Sparrow.

 

HERE is a great article by Kenn Kaufman on obligate migrants and facultative migrants that may be of interest to folks.  It is focused on his patch back in Ohio but it pertains to all migrants, even those that use the Pacific Flyway.
