It's old-fashioned Black American English. "Dem" means "them" and "was" is grammatically incorrect usage of "to be." It means "Those were water-birds."
If you didn't look up water birds in a dictionary, you can go do that if you need to.
The prefix dem means people. An example would be democracy or democrat.
The Greek root "dem-/demo-" means people.
I really can't answer the antonym part, but I can say that a synonym could be waterfowl or waterbird.
