The few avian frugivores that forage on the ground leave obvious marks (catbird, tooth-billed bowerbird) or ingest fruit whole (cassowary).
Fruits of this species are too large to be swallowed by birds other than cassowaries.
Why is the cassowary not a bird?
However, this study has shown that musky rat-kangaroos consume and carry fruits of all sizes, particularly the larger ones, which are not well dispersed by other frugivores except cassowaries.
Additionally, unripe fruits should be generally unattractive to canopy foraging frugivores such as flying foxes which likely represent low-quality dispersal opportunities for t he tree relative to cassowaries.
He bought cassowaries over the next 10 years, and two arrived every six months.
The ratites are large flightless birds, and include ostriches, rheas, cassowaries, kiwis and emus.
Among them there are jaguars, cassowaries, monkeys, sloths, chimpanzees and orangutans.
