Someone who dearly loves their pair of parrots may use {-pu’}, but everyone, including the speaker knows that it’s grammatically wrong. <http://lists.kli.org/listinfo.cgi/tlhingan-hol-kli.org>
Parrots may not have been the best example. The plural suffix for birds is usually {-mey}, the general plural suffix,
as would be expected. There is a difference of opinion, however, about which plural suffix to use for a few birds capable of mimicking speech, such as the {vIlInHoD} and the {qaryoq} (and the larger {qaryoq'a'}), with some Klingons using {-mey} but others preferring {-pu'}, the plural suffix for beings capable of using language. Maltz is a member of the former camp; he said he was never able to engage a {qaryoq} in a conversation that made any sense.
