Well, The birds have been picking their way north for a few weeks now, but because of the nearly constant rain it has been damned hard to pick them out of the radar noise. Even the HC was not reliably designating biological returns.
Last night however, once the rain moved through, we got a decent migration signature. On today’s loop, wait for the rain to pass and you will see the flight — up into the 20 dBZ range.
Tree and Violet-green Swallows as well as Turkey Vultures have made it to the Portland area. Even Barn Swallows are being reported in Clallam County in Washington. Western Kingbirds are in the Central Valley in California as well. Waterfowl numbers are down a bit too.
Last night saw heavy movement along the I5 corridor from the Canadian border south. In the Metro area the east counties had the bulk of the movement. Lots of divers and errant ducks being reported from the high Cascade Lakes. I haven’t had time to catch up on the listservs to see what has been trickling in but i did see large skeins of Cackling Geese in the Portland/Vancouver Basin when passing through. The waterfowl will be making up the bulk of the migrants from here on out.
The Barn Swallow roost is still putting on a dawn show down in Yamhill and Marion Counties along the Willamette River.
Pretty solid flight last night around the Metro Region.
In today’s loop: just as it starts look at the Yamhill/Marion County border along the Willamette River — Barn Swallows coming into roost! It starts around 5:00 PM (00:00 UTC) and lasts a few hours until around 7:00 PM (02:00 UTC). Then this morning around 6:30 AM (13:00 UTC) they begin to disperse for the day — mainly headed north.
First Ruby-crowned Kinglets are being reported as well as the first (Sooty) Fox Sparrows and quite a few more Cackling Geese showing up,
