Quote:mysticetes are birds
After review, mysticetes are not birds, sorry for any unintended confusion

It is difficult to say if the physeteridae &/or kogiidae are/were all birds or not but Physeter macrocephalus is definitely not a bird

Some strigidae are birds

Is the dumpster behind the outback steakhouse a bird?


RE: What ARE birds? - CSJ - 04-23-2019

Ok, I'm going to just jump over most of that and just state that othodoncetes are not birds - but it is difficult to say when they stopped being birds precisely
Also I just found a study that suggests mysticetes are in fact birds all along and my original instincts were right

mysticetes birds, othodoncetes not birds yes good let's move on

Quote:Is the dumpster behind the outback steakhouse a bird?
there may be birds and not birds inside the dumpster behind that infernal place but the dumpster itself is not a bird

Is it ok for a hint? Is birdness based on a physical attribute?
