Re: How Hummingbirds Hover...
I missed the first of this thread, so am not sure of the context -- but it
might be worth mentioning that the technique by which hummingbirds hover is
quite different from the method used by kestrals and most other hovering
birds. Most birds hover by means of full alternating momentum reversal (the
flutter stroke). Hummingbirds don't.

I think that could be applied to kestrels in general (perhaps with the
exception of island varieties, such as the Mauritius kestrel. Does anyone
know if that species hovers?) At least the European kestrel, Falco
tinunculus, performs the same acts of aerial acrobacy you just described. I
have personally observed members of this species doing just that.
