Catharacta maccormicki
Nov. 12
3:15 Group of shaws flew low over.
Both announced. I started close call.
I got up - began walking to him. She
sat left from him. He continued, she
got up walked but looked at very
expected call as she approached. He moved
that + she sat in nest. & they sat.
(Bl + white picture.)
A moment later they challenged once
again the D gave full challenge, female only
call.
At a more distant territory the pair
was present. A third bird landed. Both
displayed at him. He stood his ground
+ walked off as they came toward him.
Finally flew. Some of this is the posture
he assumed when he displaying
birds be adopted to Upright head + neck
tall + feathers sleeked, Body gave aspect
of attention stance wings at carpal joints
held out just slightly. He oriented his
body so that generally, except when
they forced him to move he was facing
them at 45° & he even sidled away from
them oriented that way on unless they
molested him. Saw no "turning away"
of head.
