Pigmy Owl ( Glaucidium grisea )
June 18, 1937 - 3 mi. W Panther Lake, Deschutes Co., Oregon -
A single bird was collected this morning
in a dense growth of young lodge-pole Pine.
The weather was intermittently cloudy and
raining - the time about 9 A.M. The Pigmy
Owl note was being used by me to attract
small birds - as both Dr. Miller and I
have been doing continually in this whole
region. The note was answered by the
owl which continued to give it from
another point ( c 100' away ) even after I
missed the first shot at it. Such
"shyness" or "lack of fear" seems to testify
to the owl's rarity in this region - or
we should have collected specimens sooner.
Chickadees (2) were near and cocking the
owl at its first perch - though these
birds had not come readily to my owl-
notes this time.
Dissection shows this owl fed recently
on a complete White-footed Mouse. This
may be an exception to the Pigmy Owl's
bird diet but does not explain the
reaction of small birds to the owl's presence
or notes or their "fearlessness" in close
approach of the owl.
