Dear Flammens
June 16 I give up on Owl'. Flushed 4, circled, called
grow grow grow or chaw, chaw. Very boisterous
& clumsy. She also hooted a few times. I thought
she came from a nest. She circled a long
time. Gave aerial display - 10 wing-slap
several times also called & hooted. A male
appeared circled above her in likewise
hooted. Hoots are on same pitch level
10-15 per sense, minute speed + intensity
through one sequence: Circled 5 minutes,
she landed. Watched me - I watched her. She flew
way 5. over crest fridge towards Willow Creek.
Saw her fellow male make pass at him.
He flipped up damn at her. Both disappeared.
Several minutes later 2 returned, then 3.
Long wait - moved further off. - She finally
went to a rest - in a few minutes got
up - another spot - then another. I finally
went to first found no nest. Could flush
4 anywhere. No sign of 2 or 3 when the
hill were they!
June 22 I seen Yotagy across river, in evening
foraging - crossed to this side also. Another
owl perched on ground might have been
4. Concerts this pair present accounted for.
Owl 7 + a Marsh Hawk harassed by
a Pomegranate Sparrow #1.
