Reptile Gardens has all 4 species of Mamba (genus Dendroaspis).
Bronx Zoo and Zoo Tampa have both species of living Gavialids. Bronx, Smithsonian, and Staten Island have both species of Alligator.
North Carolina Zoo has all three species of North American bears. Both the zoo and the Museum of Natural Sciences in Raleigh at one point held 5 of the 6 species of venomous snake found in North Carolina (the only one they were missing was the Eastern Coral Snake).
I know this is an older post, but does Philadelphia still have all five Panthera species? The Jaguar was the only one I did not see during my visit earlier this year (I believe the cats are all exhibited on a rotational basis?).
Ditto, but did Sylvan Heights previously hold Spotted Whistling-Duck (Dendrocygna guttata)? I started visiting that facility last year and never saw them signed or on display. That is the only Whistling-Duck species they are currently missing. They also have the White-backed Duck (Thalassornis leuconotus), which some authorities classify as a Dendrocygna species.

For all the diversity it's shed over the years, Philly still has all five Panthera species.
