Feral chickens (Gallus gallus) are reported to have existed on the island for many years from last century, but are no longer present (Guppy 1890; Gibson-Hill 1948).
During the Island Wide Survey conducted in 2009 an individual tropical shearwater (Puffinus lherminieri) was sighted on North Keeling Island. Photographs enabled clear identification of the individual and the sighting is being submitted to the Birdlife Australia Rarities Committee (BARC) for registration. This is the first known sighting of this species on the island.

Terrestrial reptiles
The mourning gecko (Lepidodactylus lugubris) has successfully colonised many oceanic islands including North Keeling Island, a success in part attributed to its ability to reproduce asexually (Cogger 1996). It is not possible to say whether the species made its own way to the Cocos (Keeling) Islands or whether it was introduced as a result of human activity (Cogger 1996).
Invertebrates
The park provides habitat for at least 26 species of crabs, the most conspicuous and probably the most numerous inhabitants of the forest floor and beach fringe. The little nipper (Geograpsus grayi) is common under the pisonia forest. The world's largest land crab, the robber crab (Birgus latro), listed as vulnerable by the IUCN, is occasionally observed within the forest but was probably more abundant prior to harvesting by Cocos-Malay people. Three species of hermit crabs are present in large numbers: the red hermit crab (Coenobita perlata); the purple hermit crab (C. brevimana); and the tawny hermit crab (C. rugosa). During the day the hermit crabs take refuge under logs and shrubs and at night they venture out to scavenge on the forest floor and beach.
The purple crab (Cardisoma carnifex) is abundant, particularly in the saltmarsh and on the fringes of the lagoon. The Christmas Island red crab (Gecarcoidea natalis) is commonly sighted on forest floor of the island and the yellow nipper (Geograpsus crinipes) also occurs in this habitat of the park. The horn-eyed ghost crab (Ocypode ceratophthalma) is commonly found on the north-western beaches, and Grapsus tenuicrustatis is common on rocky sections of the coast.
Appendix G lists the crustaceans recorded for the park and the whole of the Cocos (Keeling) Islands.
A species of cricket, Ornebius sp., occurs among the leaves of both cordia and pisonia, and Nerius lineolatus, a long-legged dipteran, and the Asian tiger mosquito (Aedes albopictus) are plentiful. Butterflies, ants, cockroaches, beetles and weevils are also present on North Keeling Island.
Spiders, a small wood-louse, centipedes, millipedes, termites, scorpions, various species of ectoparasitic ticks and mites, and a terrestrial mollusc (Melampus sp.) have been recorded on North Keeling, but as yet no earthworms have been found. Earthworms are abundant on the southern atoll.
