The goshawk feeds on a wide range of vertebrates and invertebrates, including birds, mammals, reptiles and insects. It takes its prey from the ground or in flight. It will hunt from a perch or chase birds through the forest. It is known to hunt native birds such as

The
Christmas goshawk is smaller and has more rounded wings than the nominate subspecies. Colouration is broadly similar, differing in that the hindneck, cap and ear coverts are dark grey, lacking a brown tinge. Females are distinctly larger than males.

which were accidentally introduced to the island. The threat is not only that of ant predation of goshawk nestlings, but also indirectly from potentially massive changes to the ecology of the island caused by the ants.
