Barn and Short-eared for me. I think I have heard Burrowing make calls while
hovering.

Maybe I need to clear the cobwebs from my brain. I have seen Northern Pygmy
Owls use this call during flight on many occasions, and simply forgot, when
asking the question. I guess I was only thinking of larger owls, and Wayne
has answered that question. Thanks to all who replied. I would still be
interested to hear any other reports from people, who have heard other
species of owls calling in flight.

Subject: Re: question about owl vocalizations
Darrel & all,
My personal observation is that Northern Pygmy-Owls most often make their
vibrato (screech-owl/boreal-owl-like) vocalizations while flying between
perches.
When I'm calling for pygmy-owls during CBCs in appropriate habitat, I throw
in one of those vibrato calls off and on, in between the more monotonous
toots that NOPOs make while stationary. Not sure I can really get inside an
owl's brain on this, but I think it gives the impression of a NOPO that's
moving between territorial perches.
Yesterday while hiking some upland areas for the Dallas CBC, I was doing this
when a non-vocal NOPO flew in.
