Welcome the least taxonomically correct thread ever posted to ZooChat!
I had to combine these all because had only a handful of species each and didn't really fit as their own thread.
Here I have attempted to make a complete list of Otidiformes, Podicipediformes, Eurypygiformes, Gaviiformes, Coliiformes, Trogoniformes, and Cariamiformes present in American and Canadian collections. Only information 2018 or newer was used. Information on missing holders or species, as well as information on subspecies or populations is welcomed.
