A ♂ was furthermore chased off of tree 2 by the banded ♂; the intruder flew up the creek a ways and sat unidentified in a large Valley Oak for quite some time. 1-2 other birds flushed early from tree 1 to the sap side and were not identified either.

A couple minutes later 3 other birds appeared making 4: a ♀, and 2 others, one of
