I've seen cliff and barn swallows do that, but not bank swallows. Then,
again, I've only seen a couple of bank swallow colonies next to roads
(thanks to ODOT activities - i.e. fresh artificial roadside banks).
In fact I nailed a barn swallow a week or so ago that made no attempt
to flee, and that I didn't see until the last moment. Off the subject,
but equally weird, I had a city pigeon the other day walk right under
my tire, killing itself, as I was slowly moving in downtown traffic.
I'd seen it but hadn't paid much attention, never thinking it would
turn to the right 90% and waddle right under the tire!
But if bank swallows do the road-surface hugging thing, one big, fast,
speeding truck could do it, huh?
