Quote:mysticetes are birdsAfter review, mysticetes are not birds, sorry for any unintended confusion
Most if not all monodontidae, ziphiidae and porpoises are not birds
It is difficult to say if the physeteridae &/or kogiidae are/were all birds or not but Physeter macrocephalus is definitely not a bird
Tytonidae (and by extension, Tyto) are not birds
Some strigidae are birds
