The easiest one is Brookfield. I've worked there, and grew up going to the zoo. It is really where I began my love of zoos, always has a special place in my heart. As of right now, they have two females, the third was euthenized 2 years ago when it broke it's leg. No one really knows how that happened. They think it was in a skirmish with another elephant and it happened as an accident, but no one knows for sure. They do not have the facilities to breed elephants. The Pachyderm House there houses elephants, 2 Nile Hippos, a pygmy hippo, a tapir, and 5 black rhinos (lots of breeding success with these rhinos). The house was built in 1934 and has only been sparingly renovated since then. It is cramped and old, but the keepers have added plenty of enrichment with a baobob tree outside and lots of training while indoors. No male has been housed since a large Asian male named Ziggy in the 70's. The house needs to be torn down so badly, but unfortunately, the zoo has other buildings/exhibits that have the same problems, and are worse. They are currently creating a capital campaign to solve all of these issues.
As for the other zoos, I have visited Toronto and Fort Worth, but know of the other programs. Seattle has a fantastic facility built in 1991, and has one calf, via AI from a male housed at Dickerson Park in Springfield. This was their first and only calf and I am not sure what their plans are, she is now 5 years old. Toronto has a fairly large yard for a herd of 6-7 animals, and I know they have had no calves recently, but am not familiar with anything else. Miami has both African and Asian elephants, and a male in both species, but no breeding has been done. Fort Worth has had only one calf, in 1998, but has had a recent miscarriage. The AZA expert in elephants works at Fort Worth, so their care and handling is exceptional. I am also familiar with both those open range zoos in England, but have never visited. As for the zoos involving elephants in new activities, I know of a few that have done programs where the elephants walk through the zoo. This has been a success at many places, but Pittsburgh a keeper was killed during a morning walk, so that stopped them there.
As for Maggie, I am familiar with the situation, I know it very well. The story has been all over the news here, in fact, the Alaska Zoo's idea is to build her a treadmill. This treadmill would cost about $250,000 and provide her a chance to exercise her sore joints. I understand why they don't want to move her, she is in her upper 30's and has been at the zoo for a long time, so she has accustomed to the climate and atmosphere. On the other hand, a treadmill is going to provide her with the physical stimulation, but not the social and psychological, so I don't agree with it. It is certainly a step in the right direction, but not in the best overall interest of the animal.
As for the San Diego Wild Animal Park, they sent their 3 elderly elephants to the Lincoln Park Zoo in Chicago to a brand new renovated exhibit. They sent them to Chicago to make room for 8 elephants coming from Swaziland that were going to be culled. Upon arrival, one of these elephants gave birth to a male calf that would never have made it out of the womb. The reason that the WAP sent them to Chicago was more about convienence than a death wish. Lincoln Park was opening a new exhibit just at the same time the elephants were in the process of coming to America. Two elephants did pass away at Lincoln Park following their arrival, but their deaths were not necessarily tied to the move from a cold weather to warm weather zoo. The first died of Tuberculosis, a disease deadly among elephants (as I'm sure you all know). Zoos are required to do tuberculosis tests here, so either they missed it, or she contracted a case quickly. The other elephant died of what they called "complications due to old age". That may be a cover for something else, but she was 55, the oldest elephant in the country. I can understand why San Diego sent them away, that doesn't really bother me. What does bother me is Lincoln Park. They opened a new African Journey exhibit, replacing their old Large Mammal House, but the outdoor elephant and rhino yards were completely unchanged. The indoor areas were brand new, but the outdoor yards were not enlarged or anything. It was extremely disappointing. I do agree that many zoos have no business having elephants in their collection. The problem is simply this: Zoos are supposed to built for the care of animals, but are essentially built for the public. Animals that come to zoos are the ones people want to see, and elephants are at the top of that list. So to make money and keep the zoo up and running, elephants are brought in, and sometimes their care is sacrificed for the success of the zoo.
