A couple of the condor species didn't make it.

Among coastal birds, ospreys & pelicans & the Great Blue
Heron were also very hard hit by DDT. When young, I was told
to take a good look at the few Great Blues around because
they would soon be extinct. Fortunately, that was wrong.
There certainly are a lot more pelicans around nowadays than
back then, too.

While I agree with Walt that there are a few special cases
where the benefits outweigh the costs, in general the
reasons for banning it are still most persuasive.
