Twin Spring ft., 38 mi NNW of Alturas,
Modoc Co., Calif.
May 22 (cont'd) Juncos fly close by. To hole, in
slowly (8:03).
(Tattoos of varying loudness were among
those heard previously - possibly by two
♂'s, or at least two birds)
8:04 - 6 tattoos, approx. 20 sec. interval.
♂ returns - both squawk - ♀ out of hole;
♂ to another tree close by, immediately
chased by a pr. of Bluebirds, flies away.
♀ goes in hole. 8:09 - head out of hole.
3 Distant [illegible] (50-100 yds.) steady roll of
Hairy is heard - ignored. 8:17 - out
of hole. 8:20 back in, out of sight.
8:24 Head out, then all out, Away.
8:25 ♀ Returns. Squawks. Tattoo heard,
closer tattoo. 8:27 ♀ goes in hole. 3
distant screams. ♂ returns, much squawking
by both. ♂ away. ♀ out of hole, preens;
back in hole, 8:29.
8:30 Carved "III" (or 3) on tree trunk -
no response. Tapped twice, trying to simulate
tattoo - bird looked out, then flew out
screamed 3 times, squawked. ♂ returned,
tattooed loudly close by. I left.
(For convenience in writing, I have assumed
that the ♀ is the bird in and out of the
hole. It may or may not be the same
bird every time; don't take sex signs literally)
