Last week, Mike Smith and I camped overnight at the Colville NF (T32N/R42E).
I heard a deep-voiced owl that began hooting when the moon rose at
about 11 PM or so. Most of its hoots were in pairs:

whoo-whoo ( pause for a minute or so) whoo-whoo (pause) whoo
(pause) whoo-whoo), etc.

It sounded like a medium sized barking dog and seemed to be
at the edge of a clearing or in the forest near the clearing
in Doug-fir/Cedar/larch forests.

After reading the Peterson description, I decided it must be
a Flamulated Owl. I am very familiar w/Great Horns and have
heard Barred and Pygmy Owls. However, my owl did not sound
much like the Peterson Bird Song tape. The taped birds
give a single monotonous hoot. When they do a double hoot, the
first hoot is drawn out. My owl's hoots sounded more like the
double hoot of the (extremely unlikely in that location) Spotted
Owl except a bit deeper and mine never gave more than a pair of
hoots at a time.

So, to the more experienced owl people, did I probably hear a
Flamulated? And, if not, what else could it have been?
