Chilly north winds kept migration to a minimum last night in the metro area.
However a strong river of southerly winds crammed a boat load of birds up the Central and Mississippi Flyways. I have static images of the Winds Aloft and the National Composite Radar in today’s gallery. But, head on over to Cameron’s and Paul’s sites to get the dynamic view of this marvelous show.
Well, the Western Wood Pewee and Willow Flycatcher have been ticked. The former in Clackamas County and the latter in Clark. So that wraps up this season – well, except for the Common Nighthawk, and it is not detected every year. With the NAMC this weekend and a scheduled trip to Malheur NWR next week, the only posts i’ll be putting up this season will be if something exceptional takes place. There’s still plenty of birds to move through so use the links on the side bar to keep in the loop.
Moderate levels of migration last night trickling off as a little rain started moving through and putting a damper on continued flight. Could be a good day to check your favorite patch in the Metro area. There could be a concentration of birds from the pile up that the rain can cause.
No word on the Western Wood Pewee or Willow Flycatcher yet.
Moderate to heavy migration took place all weekend. New arrivals were everywhere out in the field. I still haven’t seen any reports for Western Wood Pewee or Willow Flycatcher. Good numbers of Swainson’s Thrush were out and tonight, in a clear, full moon sky, i heard about a half a dozen nocturnal flight calls in the two minutes i spent listening.
The Atlantic Flyway finally got some love last night. For a full report head over to Tom’s recap.
A high pressure ridge is building just off shore. The leading edge is not quite here yet so the north winds associated with that are probably a day out. While that bodes well for the weekend weather it will slow north bound birds down.
Last night under neutral conditions we had some heavy movement and that will bring the next pulse of migrants into the region.
No word on Western Wood Pewee or Willow Flycatchers yet for the Portland Metro area.
No tail winds, but no significant deterrents as well. There was a moderate amount of movement last night and even heavy in patches.
We’re still waiting on reports for Willow Flycatcher and Western Wood Pewee to close out this season. But with a Blue Grosbeak and a White Wagtail in the area i doubt many will be paying close attention.
