Re: How are columbiformes (doves and pigeons) related to psittaciformes?

["David Marjanovic" <david.marjanovic@gmx.at>]

+AD4- while columbids were next to pteroclids.

This reminds me. Pteroclidae or Pteroclididae? Or perhaps even Pterocleidae?
What's correct? I've seen the first two, and the last looks logical
considering how words are derived from Herakles ( +AD0- Hercules).

+AD4- +ACIAWw-...+AF0- Almost certainly, for example, the
+AD4- derived similarities between the humerus of extant parrots and pigeons
(e.g.
+AD4- Stegmann, 1964) are due to convergence, as both the Pseudasturidae and the
+AD4- Eocene psittaciform birds described by Mayr +ACY- Daniels (1998) exhibit a
+AD4- different, presumably more primitive, humeral morphology. +AFs-...+AF0AIg-

Good to know.
