* They may be sent to other zoos. This is the most common option, as it allows the animals to be placed in a suitable environment where they can receive proper care. Zoos often work together to coordinate the transfer of animals, and may even have formal agreements in place to facilitate this process.
* They may be released into the wild. This is a less common option, as it can be difficult to find a suitable location for release and to ensure that the animals will be able to survive on their own. However, it may be the best option for certain species, such as those that are endangered or have been displaced from their natural habitat.
* They may be euthanized. This is the least desirable option, as it results in the death of the animals. However, it may be necessary in some cases, such as when the animals are suffering from a serious illness or injury or when there is no other suitable option available.
Zoos carefully consider all of these options before making a decision about what to do with extra animals. The goal is always to find the best possible solution for the animals involved.
Here are some specific examples of what has happened to zoos that have had extra animals:
* In 2019, the Cincinnati Zoo transferred two hippos to the Toledo Zoo. The hippos, named Fiona and Bibi, were born at the Cincinnati Zoo and were no longer able to be housed there due to space constraints.
* In 2018, the San Diego Zoo released a group of condors into the wild. The condors were part of a captive breeding program, and their release was a success.
* In 2017, the Los Angeles Zoo euthanized a giraffe named Caesar. Caesar was suffering from a terminal illness, and his euthanasia was the most humane option.
These are just a few examples of the different ways that zoos have handled the issue of extra animals. Each situation is unique, and the best solution will vary depending on the circumstances.
