That's the most common theory. I've seen Little Ravens here in Australia take
barbeques in this way. If the wind changes direction, they change trees to stay
in the smoke.
Corvids will also lie spread-eagled over ants' nests and let the ants crawl all
over them. It's
thought that either the ants actively remove parasites from the feathers, or
they leave a liberal
coating of antiseptic secretion on the feathers, or perhaps a combination of
both (so that both
parasites and micro-organisms are dealt with).
