Fascinating - is there an evolutionary just-so-story? Hmm, birds have xx males and xy females, right? Also I guess one should distinguish between monogamy, pair-bonded-for-life, and not-sleeping-around-at-all. I vaguely thought that some p-b-f-l birds turn out to have a surprising degree of adultery. In fact I thought p-b-f-l actually had turned out to be really rare, even in birds, except for albatrosses or something, so ignore me. Anyway, it should be noted that jhereg (and maybe orca?) are dimorphic in the hawk mode. SKZB is really on top of his universe.
