I was going to ask a question about which zoos still had the most bears, and then went back to the first post and re-organized the data to answer it.
With the exception of Saint Louis, I am still going off the first post. It looks to me like Cleveland and Cincinnati have gone through some major changes as well but I'm not fully up to date. I also marked the former panda holders since three of them seem to have a chance to continue or return to their programs.
Three or More Bears
Brookfield – polar & brown & sloth
Cleveland – brown, black & Andean & sloth & sun
Columbus – brown & black & polar & sloth
Memphis – polar & brown & black (formerly panda)
North Carolina – polar & brown & black
Oakland – brown & black & sun
Toledo – polar & brown & Andean
San Diego Zoo – polar & brown & Andean & sloth & sun (formerly panda)
Saint Louis – polar & brown & sun (formerly Andean)
There are around nine zoos with three or more kinds of bear, two of which held four very recently. I think it's interesting to point out that almost every single one of these holds polar and brown among the list. I personally hope this number can increase a little bit. I have to admit it's interesting to know Brookfield is one of such few facilities. I know Cleveland has renovated recently, where do they fall today?
Two Bears
Atlanta – giant panda & sun
Audubon – black & sun
Cheyenne Mountain – brown & Asiatic black
Detroit – polar & brown
Gladys Porter – black & Andean
Great Plains – brown & black
Henry Vilas – polar & brown
Lincoln Park – polar & black
Little Rock – brown & sloth
Louisville – polar & brown
Minnesota – brown & black
Oklahoma City – brown & black
Oregon – polar & black
Philadelphia – Andean & sloth
Reid Park – brown & Andean
San Antonio – black & Andean
San Francisco – brown & black
Sedgwick County – brown & black
Smithsonian’s National Zoo – Andean & sloth (formerly pandas)
Tampa – black & sun
Topeka – black & sun
Utah’s Hogle – polar & brown
Virginia – Asiatic black & sun
Woodland Park – brown & sloth
Atlanta has the most unique combination on this list, specializing in two bear species that are fairly rare. The National Zoo currently has two species but may return to three if the panda program resumes. Brown bears and black bears was the most common combination, but noticeably polar bear facilities usually also hold brown bears, with Oregon the main exception. As a result of these preferences, brown bears are almost always held alongside black and polar bears, with Little Rock, Reid Park, and Woodland being the exceptions, while black bears appearing alongside tropical species seems slightly more common. Philadelphi and Smithsonian National both focus on tropical species.

Not a very helpful comment here, but Denver and Milwaukee County were once famous for their bears and both held four species of bear more than five years ago but are now down to a single species. I really hope these two facilities are eventually able to construct new exhibits and expand their holdings for this group. I believe Cincinnati's renovations will soon welcome back a second bear species?
