African Pied Kingfisher is smaller than a Belted Kingfisher (26-28cm
compared to 33cm). Most Kingfishers can hover "in still air" but
many of them aren't fishing (they're grasshoppering or lizarding).
I watched a Belted Kingfisher this morning hovering over the
Neawanna River, wind was 0-5 from the SW and the bird was hovering
in an e-w orientation.

I picked up on the whole hovering thing, too. The weakness in the
program is in the tendency to make absolutest statements. On the
issue of hawk hovering, Red-tails and Rough-legs hover, but into a
fairly stiff breeze. Ospreys, I'm not so sure, but they may be able
hover (with effort) in still air.

Mike Patterson The common view of science is that it is a sort of machine
Astoria, OR for increasing the race's store of dependable facts.
mpatters at oregonvos.net It is that only in part; in even larger part
it is a machine for upsetting undependable facts.
