As a high pressure ridge builds out over the Pacific winds are shifting and coming with a northerly component. That and early evening rain kept migration to a minimum last night.
The flight didn’t get started until 10 or 11 last night and really was on the meager side. But it’s still early in the season.
Field anecdotes: the Columbia river bottom lands show dramatic decreases in the Cackling Geese. Swan numbers are way down. And on a trip to Ridgefield NWR on Sunday — not one American Wigeon. Still plenty of Shovelers, Pintails, Gadwalls and Mallards, but Teal and Rudy ducks were in short supply. However, the Tree Swallows are back in force, and in the Clatskanie area i picked out a couple of Violet-green Swallows as well.
