Dallas' collection is better than I remembered it being, especially when it comes to birds-of-prey, waterfowl, and cranes. Chester still has the superior collection, though. I'm not sure about Dallas, but Chester's number will actually be higher than what I've reported due to them having several parrot species behind the scenes as well as some species I've missed on my visits that I couldn't remember exactly. I also left out some species I'm unclear of due to changes to the zoo since my last visit. It's worth noting that a good few of their animals are singletons and not really present for breeding, but they still do have some very choice breeding programs in the green-magpie and other more endangered species. In general they seem to have a rarer collection as well, despite Dallas having a few heavy hitters.
It should also be noted that Dallas' exhibitry for their birds is rather bland for the most part. Rather simply-- though nice-- aviaries scattered throughout the zoo, a large waterfowl pond, and a couple of walk-through aviaries. Chester on the other hand, while they do still have a few rather simply aviaries, has some truly amazing walk-through aviaries in Monsoon Forest (still counts imo..) and Tropical Realm.
In this case I'm voting 2-1 Chester and I can't really see much of an argument to chance my mind.
