If the alligators are back it hasn't been reported that I've heard!?…are there alligators in The Swamp? I can’t remember seeing them since at least the time the flamingoes moved in.
I actually think birds is the most fascinating one. I think two, three, four or so years ago, Lincoln Park won handily on birds - we had no owls, no toucans, no flamingos, no wild parrots, no mixed outdoor aviaries, only crowned cranes - but since Adkesson took over, we've really seen Brookfield's bird collection improve rapidly, with new aviaries constructed, and it's been a nice surprise to watch that happen.I will give Lincoln Park big cats / bears. Brookfield isn’t great in those departments, despite how relatively new their bear exhibit is. They might take birds. For now they have much better ape exhibits. Give it a few months and that’ll have evened out a fair bit. Definitely take smaller primates. I really like the cactus mice and Brookfield doesn’t have an answer to that.
There's also a chance I'd have let Lincoln Park win on small mammals, especially during the elephant shrew seemed gone for good at Brookfield. Their return as well as the new marsupials and small cats have done a lot to help here.
