Due to the range in altitude in the park, there are a variety of fauna habitats. The foothill forests contain kangaroos, wallabies, and several species of possums and sugar gliders. Smaller mammals such as native rats and mice inhabit the plateau. Wombats occur in all habitats. The alpine silver xenica is a species of butterfly found only on the plateau of Mount buffalo. Bogong moths shelter in rock crevices at the horn and it is common to see birds darting in and out of the cracks to feed on them during the day and bats doing the same at night. Peregrine falcons sometimes nest in the granite rock faces. Crimson rosellas are abundant throughout the park.
