21 March 2017 – PNW Migration Update

Rain, heavy at times and easing up through the night.  Sigh.

There was a nice south wind, so anxious birds braved the weather and picked their way north.  Not in great numbers but fairly widespread as the weather would allow.  It’s tough to pick them out between the rain cells so we have the Hydrometeor loop today to aide in finding the birds; a little like finding Waldo.

American White Pelicans have been reported in the region, a few more Western Kingbirds and Osprey as well.  Ruby-crowned Kinglets are starting to sing.  It’s a wonderful song and we only get a small window in early spring to hear it before they clear the area as they head north to the breeding grounds.

Pacific Slope Flycatcher reported in the Central Valley is a first arrival.

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:”

 

19-20 March 2016 PNW Migration Update

Really nice movement over this weekend.

In San Diego:
More Pacific-slope Flycatcher, Bullock’s Orioles and Wilson’s Warblers.

Central Valley:
Black-throated Gray Warbler

Willamette Valey:
Orange-crowned Warblers, and a solid push of Violet-green Swallows.

I’m having problems uploading the loop from last night — i’ll try later.

17 March 2016 – PNW Migration Update

Well, after a week of rain we finally got a clear night.  Birds took flight but in very moderate numbers.  There were a few patches where the density reached the 20 dBZ level but not many.  It’s still early.

In the region: first Violet-green Swallows, Turkey Vultures are increasing, Black-bellied Plovers have been seen and the first reports of returning Osprey.

In the San Diego area the Swainson’s Hawks are staging in Anzo Borego, and the first Pacific Slope Flycatchers are being reported.

Barn Swallows have made it to the Central Valley.
