Well, after a pretty miserable few days it looks like the current system weakened a bit last night. We still had onshore crosswinds but the birds were on the move in the metro area last night. It didn’t sustain heavily through the whole night and again the east counties had most of the action.
Quite a few more ducks are being reported. The Sandhill Crane numbers have dramatically increased on Sauvie Island. I’ve been quite busy so i wasn’t paying attention to the listserves last week. I only got out into the field once this weekend and it was pouring rain, so it was a short trip. But there were quite a few Swainson’s Thrushes moving just before dawn.
The stubborn ridge of high pressure is keeping the local winds out of the north. but i don’t see that lasting too long as another low pressure system is spinning up out it the Pacific. You can see this on today’s wind map.
Over all the southern reaches of our area of concern saw the best migration action last night; again, it was concentrated along the flanks of the Cascades and east of the Willamette. There was a short but heavy flight across the Straight of Juan de Fuca last night as well.
Still haven;t heard of any Swans in the area but the Cranes are on the move in good numbers. They even were reported in Clackamas County — not a common report by any means.
