Any pig meat has a very very distinct smell to me.

I can also recognise cooked poultry vs beef by smell (more so when raw, but when cooked I'm sure I can figure it out as well).

I thought most people could.

My wife has a powerful sense of smell, and she vociferously complains about the odor of pork, which smells no different to me than any other meat.

They smell very distinct to me as well. Just as they taste much different, they smell different in similar ways to me.

I think turkey, duck, and chicken are distinct while cooking as well. I’d have a hard time distinguishing gamey meats, though. I couldn’t tell you if it’s venison or moose, for example.
