At the ACCB, the team doesn't exclusively care for the focus species of birds and turtles. 
Mammals also live and are cared for at the ACCB. They usually come from confiscated animals or have been rescued from poachers' traps. 

Kept but not bred include the Indochinese silvered langur (Trachypithecus germaini, EN), the Pileated gibbon (Hylobates pileatus, EN), the Bengal slow loris (Nycticebus bengalensis, EN), the Smooth-coated otter (Lutrogale perspicillata, VU), and various species of birds of prey, as well as, on rare occasion, the Sunda pangolin (Manis javanica, CR). All of these animals have in common that they were taken in by the ACCB and not reintroduced because they would not be able to survive in the wild. The ACCB holds a total of 1,025 individuals from 36 species (as of July 2023).

Where possible, these animals are prepared for release into the wild. However, this is particularly challenging if the animals were previously kept as illegal pets.
