(9 November) and was greeted with a full opened-winged walk by the subordinate
♂. Seconds later the other ♂ flew up as well and proceeded
to pick up where he left off. The subordinate bird did not

group can be achieved - a ♂, for example, may under some
circumstances be accepted if he fully and clearly understands

At dusk only 2 birds were present, a ♂ and ♀. The ♀
disappeared rather early, leaving the ♂ on the granary, where
he mostly flew hawked (probably for the oak moths). At
roost time he headed over my head directly toward
Chongo gulch, where I lost him. This is probably the same
hole where they were seen going by us in September.
But wow - when I lost him he was near the path leading
around the hill that I take toward Chongo. This may be
a first - birds roosting somewhere entirely off their territory.
(An alternative explanation, perhaps, is that he is budding from
Chongo (or Buckeye?) and still returning there to roost.
