FAP 1961 Calyptr anna March 25 Berkeley, California Male singing and behaving territorially using upper twigs of Bumma ilicifolia trees overlooking a hillside garden area. Not present earlier -- at least not regularly. April 15 In past three weeks, a male anna present in the area, singing and driving away intruders and behaving territorially, but not present regularly.
