Australian Ibis at North Stradbroke Island


Species:molucca
Genus:Threskiornis
Subfamily:Threskionithinae
Family:Threskiornithidae
Order:Ciconiiformes
Class:Aves
Phylum:Chordata
Kingdom:Animalia

The Ibis walk everywhere on the Island.
This old bird was across the road from the YHA at the park.
He was very tame, and was quite happy to let me take photographs.
Eventually he simply walked away into the bush across the road.

Preferred habitats include swamps, lagoons, floodplains and grasslands, but it has also become a successful inhabitant of urban parks and gardens.

The Australian White Ibis is identified by its almost entirely white body plumage and black head and neck. The head is featherless and its black bill is long and down-curved. During the breeding season the small patch of skin on the under-surface of the wing changes from dull pink to dark scarlet. Adult birds have a tuft of cream plumes on the base of the neck. Females differ from males by being slightly smaller, with shorter bills. Young birds are similar to adults, but have the neck covered with black feathers. In flight, flocks of Australian White Ibis form distinctive V-shaped flight patterns. Another common name for this bird is Sacred Ibis, but this more appropriately refers to a closely related African species.

Australian White Ibis nest in large colonies, often with the Straw-necked Ibis, T. spinicollis. The male secures a pairing territory on a branch of a tall tree in order to attract a female. The courtship ceremony involves the male putting on a noisy display, as well as showing aggression towards other males. When a female arrives, the male attracts her by bowing from his branch. He then offers the female a twig, forging a bond when she grasps it and they begin to preen one another. Once the pair bond is cemented, the birds fly off to build a nest at another location.
