It would not be surprising to find enlarged testes in WCSP in June, but
these are full sized to form a well developed cloacal protuberance which
is generally associated with territorial males. Information on the
circumstances under which they were collected (ie. were they shot while
singing from their territorial perch) would go a long way toward buttoning
down this mystery, but I suspect you have some pretty good evidence of
breeding.
