Hi Marv,

Its a lucky day whenever we get to witness owls and their behavior. That
was a "concealing" behavior. All Owls try to break up the "typical owl
shape" when the perceive threat. For nearly all species this involves just
what you describe. I have seen this with Elf Owls, Saw-whets, Boreals,
Long-eared, Short-eared, Screech Owls, Snowy Owls, and both Northern and
Ferruginous Pygmy-Owls and even the Northern Hawk Owls. Owls with
"ear-tufts" also involve their tufts. Owls considered "earless/tuftless"
such as Pygmy-Owls and Snowy Owls sometimes even manage to show residual
tufts. I have seen this behavior in response to potential predators such
as Eagles, Hawks and larger owls.

Some examples:
Snowy Owl Concealment/Cryptic

Northern Hawk Owl

Ferruginous Pygmy-Owl

Short-eared Owl:

Northern Pygmy-Owl
