A Swift-ly Tilting Planet
There are no swifts in Missoula. Except when there are. When there are is migration, and it is happening now.
As an East Coaster swifts were easy. There are Chimney Swifts, and they nest in chimneys. They are swift-shaped and move swiftly, and are different from all the other birds in both looks and call (although I guess you could mistake them for swallows if you were in a hurry, or drunk,) and that is that. The swift issue may be tabled forever.
Not so out west! Here we have Vaux’s Swifts that nest in snags and Black Swifts that nest on cliff-faces near waterfalls and White-throated Swifts that nest on cliff-sides that are not near waterfalls. They all look a bit different, to be sure, with varying sizes and pale bits and tail shapes. But not different enough to be distinctive in low light against an open sky, which is where and when you see swifts, especially if you are me, with the added bonus that you see them when you are walking the dog and not carrying binoculars as opposed to when you are actively birding. And you see them in the fall migration, when they foresake their distinctive breeding habitats and ranges and migrate promiscuously, sometimes in mixed flocks, all down towards Mexico. They’re nearly as bad as swallows, even when you’re sober.
All this is to say that I don’t know if I saw this:
or something even more unlikely.
But it definitely means that summer is ending.
