Y-e-s. I think the slight difficulty attaching to that task might be hinted at by the name of the bird in question. "Swift" as in fast and not Swift as in Irish satirist.
But enough negativity. Completely free of charge, here's my three stage classification for quantifying the number of individual birds in a flock of swifts :
- More than one
Now if only the bird experts wanted us to count the number of slows, slows are a skoosh.
"There were hunners here a minute ago, hunners."
