23 May 2017 – PDX Migration Update

The migrants continue to fill the airways at night.  At this time it is just filling in – the major waves have moved through or are settling down and establishing nesting territories.  The last of the wintering ducks are down to onesies and twosies and the male breeding ducks are showing signs of molting into eclipse.  There remains legs in the migration but it is beginning to wind down.

Willow Flycatchers are still under represented as seen HERE.

22 May 2017 – PNW Migration Update

Our ridge of high pressure is holding and we should have another day or two of this exceptional weather.  There is a deep trough behind it that we need to keep an eye on though.

Last night was another good night for night flight.  It petered out in the northern portion of the I5 corridor but still decent.  Medford had one of it’s best nights of the season.  So, i’m putting up the I5 radar loops; Medford to Seattle in today’s gallery.

I didn’t find any Willow Flycatchers this weekend but they are definitely filling in as seen HERE. I did come across my first Lazuli Buntings, but they have been here a couple of weeks now; i just can’t get out into the field as often as i like.  HERE is their map.

18 May 2017 – PNW Migration Update

A very good night for flocks flying free.  All alliteration aside, again we had clear skies and gentle winds out of the north.  The upper left corner was cooking green doughnuts last night with a really nice flight across the Strait of Juan de Fuca over to Vancouver Island.

One more Willow Flycatcher was added to the MAP.

17 May 2017 – PDX Migration Update

The Willow Flycatcher is on the MAP.  Only a couple but that is how it starts; i expect them to be filling in over the next week.  We should definitely be able to hear them this weekend.

More rain in the Metro area last night and any migration that took place was subdued and opportunistic as they dodged the rain.  Winds died down over night but they still have a northerly component due to the advancing high pressure ridge.  It looks like we are still in for a break in the rain and probably for an extended period; should be great birding weather this weekend.

Looking at the wind map you can pretty much picture the migration scene on a national level, but to confirm your mental image i put the National Radar Composite in the gallery today.

RTX just came back on line — just in time to log the rain.  So we’ll save some disc space.

KRTX has returned to service.  5/16 1 am PDT (08Z)

Still no northern Willamette Valley Willow Flycatcher reports (which is a bit odd), but the Eastern Kingbirds are back out on the Sandy River Delta.  Nationally migration moves apace very nicely.

The weather looks bleak for the next day or two but there is a nice high pressure ridge building over the Pacific that should move the storm track to the north and bring in some very nice, and needed relief.  It looks really broad so we may get extended nice weather through the weekend.

The RTX radar is on the fritz again

KRTX will remain out of service until further notice due to failure of a critica
l component.

So, i grabbed the Gray’s Harbor (LGX) loop from last night.  Migrants are still on the move and staying out in front of the rain squalls.

Still no Willow Warblers in the northern Willamette Valley.  But the Bullock’s Orioles’ main contingent has arrived as well as the Yellow Warblers, Western Tanagers and Black-headed Grosbeaks.
