I know this thread hasn't been updated in a while, but a recent update from Rosamond Gifford Zoo gives a rather disappointing update on HPAI in zoos. The Rosamond Gifford Zoo has announced they will be demolishing their "main pond", home to Chilean flamingos and a variety of waterfowl, and replacing it with a botanical garden. While not the only reason given, one of the reasons specifically mentioned by the zoo is the threat of HPAI:
maintaining the waterfowl pond generates otherwise avoidable water waste, and also attracts wild birdlife that can bring deadly diseases like Avian flu to our zoo grounds and potentially spread them to the animals in our care

2024 Spring Appeal
Species housed in this exhibit are: Chilean flamingo, Ross' goose, greater snow goose, West Indian whistling duck (although I've only seen this species here once), green-winged teal, African yellow-billed duck, emperor goose, bar-headed goose, red-breasted goose, American goldeneye, hooded merganser, falcated teal, and possibly lesser white-fronted goose (still listed on website, but I haven't seen the individual since 2021). Blue cranes are located near this exhibit as well, although theoretically I don't think that exhibit will be impacted by this development.
