Successful transfer of a Goodfellow's tree kangaroo (Dendrolagus goodfellowi) pouch young to a yellow-footed rock wallaby (Petrogale xanthopus) surrogate.

A 47-day-old orphaned Goodfellow's tree kangaroo (Dendrolagus goodfellowi) joey was successfully cross-fostered onto a yellow-footed rock wallaby (Petrogale xanthopus). The joey was subsequently taken for hand-rearing at age 5 months. This is the first report of the cross-fostering technique, well-established in other macropods, being applied to a Dendrolagus sp. This technique can be considered as a viable option to raise young orphaned tree kangaroos, and as a tool to accelerate breeding in captive breeding programs of Dendrolagus spp.
