The Rock Parrot they frequent the coastal dunes, mangroves, marshes, agricultural areas, lightly treed savanna, areas of mallee (Eucalytus slender), scrublands abound where the Salt plants (Atriplex). Also visit the coast, where small rivers flow into estuaries. They appreciate the plantations of casuarina and margins of brackish water bordering the coasts and rocky islets where nests are less susceptible to predation. Throughout the year, These birds do not deviate more than several hundred meters from the sea.
Large gatherings of the Rock Parrot, sometimes, There are land, When there is abundance of food. But, like most of Neophema, this parakeet can be hard to spot, and it will only be visible when you take flight due to some danger.
Their plumage is not anti-absorbente and often remains wet, which gives it a darker shade. They tend to use the same Burrows to the Pacific Shearwater (Puffinus pacificus), the 2 species sometimes have the same habits and the same mating rituals.
Reproduction:
The Rock Parrot reproduced from august to december, sometimes in February. Occasionally, There is a second litter.
The nest is placed in the crevice of a low cliff, on a facade or on some rocky ledge. Since relatively recently, they have come to nest on small islands of limestone, the entry hole is often hidden behind a curtain of vegetation.
Sometimes, abandoned Burrows of the Pacific Shearwater (Puffinus pacificus) they are used as a nest by the Rock Parrot. In other cases, These parakeets usurp active nests of the Paรญno Pechialbo (Pelagodroma marina).
Spawning contains 4 or 5 eggs and your incubation lasts a few 18 days. The chicks are altricial and stay in the nest during 30 days.
Food:
The Rock Parrot are, above all, vegetarian. They like to eat cultivated seeds, fruits and a variety of herbs. They also eat young shoots, shrubs and plants that are tolerant of saline environments.
Distribution:
Size of the area of distribution (reproduction / resident): 1.700.000 km2
There are two separate populations by the Great Australian Bight, which does not offer the suitable coastal islands for nesting.
The Eastern population extends from about Robe, Southern Australia, in the East, to Nuyts archipelago, approximately 133 ยฐE in the west (although breeding records in Kangaioo Island, they have not been confirmed).
The Western population extends from Israelite Bay to archipelago of the Recherche.
In Western Australia, to the West around the Cabo Leeuwin and to the North of Shark Bay.
To the North of Perth the species nests in the continent, but in other parts, birds occupy the coastal islands, at least for breeding, also sometimes traveling from the Mainland to settle on the islands of the coast.
The population of the Rottnest Island on the coast of Perth suffered, in the past, illegal capture, but has grown rapidly in recent years.
The Rock Parrot they are considered common and partially nomadic residents throughout its area of distribution; so far, coastal islands have not been subjected to the same pressures of development than continental zones.
Conservation:
โข Current category of the Red List of the UICN: Least concern.
โข Population Trend: Decreasing.
In accordance with Handbook of the Birds of the World, This species is not threatened at the global level. His surprising absence from the region of the Great Australian Bight It can be explained by the lack of sites available in which to nest. In these places, rocks are in fact very limited in number, so the nests bad are protected in the absence of rocks and crevices where they serve this species as a refuge against the attacks of predators. The Rock Parrot they prefer to nest on the islets off the coast, Surely in order not to deal with rats, foxes, cats, lizards, monitors and monitor lizards.
Its population is estimated above of the 20,000 individuals.
