>>Actually, there is no circumstance in which a group that consists of only birds and frogs (and nothing else) could be considered paraphyletic, so it is not necessary to be ambiguous.

The other circumstances I suggested would include OTHER TAXA. This particular case is clear. But sometimes it is unclear whether a grouping is paraphyletic or polyphyletic. Under those circumstances the use of the term non-monophyletic is completely appropriate, not "dishonest".

You sure have a big ship on your shoulder, CKing.
