09 May 2016 – PNW Migration Update

Light to moderate migration last night.  The high pressure ridge we were watching at the end of last week moved north instead of inland.  That kept the winds out of the north.  Birds are moving through just not at peak densities.

Looks like it was a good weekend to be looking for shorebirds on the north coast – if timed right.  Take a look at what my friend Bob scrounged up HERE>

I haven’t caught up with the listserves but Western Tanager, Cassin Vireo, Yellow-breasted Chat and Lazuli Bunting are in.  And this morning i heard the flight calls of Swainson’s Thrush overhead; at least a half a dozen.

Nationally birds were dodging some heavy weather but in the breaks and clear air heavy migration was taking place.

29 April 2016 – PNW Migration Update

Last night was another night of moderate migration, just like yesterday.  A high pressure system is pushing in from the south and the winds at the head of the ridge are out of the west.  Crosswinds are not too much of a problem but certainly no incentive.

Heard around the listserves, Olive-sided Flycatcher, Hammond’s Flycatcher, Dusky Flycatcher, Pacific-slope Flycatcher, Western Tanager, Bullock’s Oriole; all being reported in the region.  Even a Lazuli Bunting report.

HERE’S a great read on PNW migration.  Put into perspective with migrations in other N American Regions, by luminary David Irons.

One of the things he brings up is a pet peeve of mine; the use of the term “fallout” in the Pacific Northwest.  There is no such thing here.  There may be a temporary bunching up of migrants in certain weather conditions where you might get to see 50 Yellow-rumps instead of 25.  That, folks is not a “fallout”  THIS is a “fallout”.

I miss John Stewart, sorry Trevor, you don’t cut it.  So, “Here it is, your moment of zen:”

 

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.

12 April 2016 – PNW Migration Update

Another night of moderate migration.  Seems like most movement was departures.

House Wren seems to be the new wave of summer residents to arrive en mass. But reports of early Western Tanagers and Swainson’s Thrush are popping up in the southern reaches of Oregon.

A new low pressure system is building offshore. If it holds off from forming rain cells we might get a nice southerly wind to push migrants northward tomorrow.

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.

01 April 2016 – PNW Migration Update

Same as yesterday — light winds in the eye of the ridge and birds are on the move!

Lots of new migrants to report: in the San Diego area – Western Tanagers, Nashville Warblers, Wilson Warblers, Warbling Vireos, Black-throated Gray Warblers and Bullocks Orioles.

In Oregon: Chipping Sparrows, more Purple Martins, Cliff Swallows, Caspian Terns, Black-bellied Plovers, flocks of Dunlin, Calliope Hummingbird, and White-throated Swifts.

I threw in a loop from Key West in today’s gallery because it is always cool to see birds taking off from Cuba and head across the Florida Straights.
