The world is a big place with plenty of room to hide. I would not be too surprised if someone found a passenger pigeon.
But I doubt anyone is ever going to find a dodo...
Unlikely that we will find passenger pigeons. Apparently they need a flock of significant size to stimulate the hormones that lead to breeding. A flock of the size needed would not remain hidden for a century. More likely to be able to reengineer the dodo through DNA work than the passenger pigeon species.
But I doubt anyone is ever going to find a dodo...
Oh come now, Yeb could find it...
