Feb. 3 Queens Road, Berkeley, Caly,
stiffly perched with tail pointing
upward. I stood about 5 feet
away from it in the shelter of a wall
and shrub along the top by that wall,
while the dive displays were concluded
and the encircling display performed.
After the last dive, the displaying $^{\circ}$
took up perches 15-20 feet away
from the intruder and moved to these
along a circular path, giving a songy
set pattern as described for earlier
examples of this display. Some
variation occurred in the perches
as the surrounding area offered
an abundance of them. There were
three to five perches per circumference.
After the 4th circle, the $^{\circ}$ simply
flew up and high, toward the
eucalypts to the west. After about
10 seconds the intruder began to
chirp, moved a short distance
within the twiggy one and then
took wing to the east.
