Thank you, @Zoofan15. After doing an overview of the U.S. Asian elephant population, I think the following institutions, from probable to possible, would be the best, potential candidates to receive Burma.
Honolulu Zoo - Honolulu, Hawaii
• Honolulu would be the perfect forever home for Burma! Honolulu currently has two cows, Mari (7 years older than Burma) and Vaigai (3 years younger than Burma), who would, theoretically, be great companions for Burma. Also, adding Burma to their herd would enhance the current dynamics at Honolulu, and bring the herd to three, the minimum number by AZA standards. In addition, the elephant facility received a major upgrade a few years back, so Burma would be living in a state-of-the-art facility. Further, the climate in Honolulu is comparable to that of Southeast Asia. Honolulu checks all the boxes.
Los Angeles Zoo - Los Angeles, California
• Los Angeles currently has three older cows and a mature bull, who would, theoretically, make great companions for Burma. Also, their elephant facility is one of the best in the country, and has the space to accommodate more elephants.
San Diego Zoo - San Diego, California
• San Diego currently has two older Asian cows, who would, theoretically, be great companions for Burma, especially Mary, the social butterfly of the herd. Also, San Diego specializes in caring for elephants in their golden years, so Burma would receive the best of care as she gets older. However, with the recent acquisition of two adolescent African bulls, it appears San Diego may be transitioning from geriatric to bachelor.
Miami Zoo - Miami, Florida
• Miami currently has two (1.1) older Asian elephants, who would, theoretically, be great companions for Burma, and Ongard, the adolescent Asian bull from Melbourne. I'm not sure if Miami intends to transition from geriatric to breeding once Dalip and Nellie pass away but, regardless, Miami does have a great facility for their elephants.
Audubon Zoo - New Orleans, Louisiana
• Audubon currently has three older cows (two of which are pretty much the same age as Burma), who would, theoretically, be great companions for Burma. Also, the elephant facility received a significant upgrade a few years back, so Burma would be living in a state-of-the-art facility.
I believe Miami has plans to become a breeding facility once Dalip and Nellie pass; that's why Ongard was transferred there, although he's owned by San Diego. There were talks of him being used for AI in the meantime, but i'm unaware if he's begun training for such procedure.
San Diego, LA and Honolulu are the likely options for me. LA would be great for Burma, suits all the categories. Honolulu definitely seems most likely, with a new state of the art facility and only two cows. San Diego have five elephants already, and although they could hold a sixth, i'm not entirely sure. Still we can't rule them out, they've had connections with NZ in the past, namely the Mila transfer.
