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.

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.

27 March 2017 – PNW Migration Update

This is way past getting old so lets not discuss it.

Black-headed Grosbeaks in San Diego, Ospreys, Rufus Hummingbirds, and most Swallows are firmly established in the Metro Region.

Elsewhere at the national level we can see the SE and Gulf Coast hopping.  A few storms to dodge here and there but plenty of open air.  Thanks Paul!

After the wettest Feb on record, PDX is knocking on the door of another record in March. Record: 7.89″. Current: 7.00″

02 May 2016 – PNW Migration Update

Nice southerly flows and heavy migration across the Pacific Northwest.

Consistent reports for Black-throated Gray Warbler and new reports for Swainson’s Thrush and Black-headed Grosbeak.

 

11 April 2016 – PNW Migration Update

Since i take the weekends off from this project i’m not sure what the birds were up to Friday and Saturday night.

But i do know what they were doing in the field.  Duck numbers are down, Snow Geese are gone but there are plenty of Cacklers still around.  A few more shorebirds are around.  The snipe are winnowing, Sooty Grouse are booming and a few cranes are practicing their mating dance.  Common Yellowthoats are firmly entrenched. Chipping Sparrows are dotting the landscape.  And northbound Blue-winged Teal are popping up in their usual low density numbers but to the delight of those who happen upon this strikingly beautiful bird.

On the listserves; MacGillivray’s Warbler, Black-headed Grosbeak, and Western Tanager have made it to the Willamette Valley.

Outliers of Hammond’s Flycatcher, Swainson’s Thrush and Western Wood Pewee have been reported as well.  Treat those as you will.

Last night we had light to moderate migration across the region so i am going to conserve cloud space and only put in the RTX loop today.  LGX and ATX both had approximately the same density.

08 April 2016 – PNW Migration Update

Unfavorable but light winds did not deter migrating birds.  Most of the action was up in the Seattle area with a very strong flight across the Strait of Juan de Fuca.  Also, a significant movement along the coast.

Sora, Chipping Sparrow, Black-headed Grosbeak and Western Wood Pewee have now been reported in the northern Willamette Valley.

29 March 2016 – PNW Migration Update

Continuing north winds probably hampered migration a bit, but not completely.  There was a nice push of birds in east Clark County probably originating from Steigerwald.

Looks like this ridge of high pressure may stick around for a while.  That will bring some much needed relief from the rain, but as long as it hangs in the Gulf of Alaska we will continue get these north winds aloft.

One glance at the Winds of the Earth and you can pretty much guess the Central Flyway and possibly the southern part of the Atlantic Flyway is set up for decent migrating conditions.

Black-headed Grosbeaks have made it to San Diego, Common Yellow-throat and Northern Rough-winged Swallows to the Willamette Valley.
