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:”



28 April 2016 PNW Migration Update

Light winds out of the north probably hampered migration a bit but not totally. We had moderate migration last night around the metro region.  Take a look:


I still haven’t caught up with the listservs. But Bullock’s Orioles are in, shorebirds are moving through and duck numbers are dwindling.

26 April 2016 – PNW Migration Update

I’m back.  I have no idea what went on over the past few days.  I haven’t had time to check the listserves either.  And i only have a couple of minutes this morning.

The winds are not really helping today as a weak high pressure system is moving in, so migration last night was moderate with only a few early (departures) 20 dBZ returns.  Take a look:


20 April 2016 – PNW Migration Update

Another solid night of nocturnal flight.

I’m packing up for a road trip — be back next week some time.  The links in the side bar – you know what to do.

19 April 2016 – PNW Migration Update

Heavy, even extreme in places, migration last night.  Check out the LGX (Gray’s Harbor) loop and note the extreme, 30+ dBz returns, right at the wrack line.

The whole region was filled with birds — enjoy:

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.

15 April 2016 – PNW Migration Update

Heavy rains, as the low pressure trough moved through, kept birds grounded for the most part.  There was light to moderate movement as it subsided – most likely the strong fliers like waterfowl.  The best movement was along the coast; probably because the rain moved past earlier in the day.  So, i put in the LGX (Gray’s Harbor) loop today.

The high pressure ridge is slipping to the south so we will probably get onshore easterly winds instead of the northerly winds predicted yesterday.  It should still be nice weather to get out birding this weekend.

On the national level; except for the SE where there is some weather, the board was lit up from the Atlantic to the Great Plains.  Check out the wind map and you can see why.  Just for fun we’ll watch the birds cross the Straits of Florida today – Key West is in the gallery.
