The Little Corella's voice could be a drawback to those attempting to hold this species in suburbia and re­ main appeasing to the neighbors. It has a series ofhigh pitched screeches and a waving wail which can be heard for many kilometers. To accurately sex these birds, I suggest surgically sexing, a com­ monly performed operation these days. It should be performed by an avian veterinarian. The Little Corella occurs over a vast area ofmainland Australia, mainly the drier interior and to the northwest coast. They also occur in various sub­ species to the islands to the north of Australia. There are also several sub­ species on the mainland ofAustralia. They can occur in massive flocks of literally thousands of birds, to some­ times a solitary pair. Man has cropped areas where the Little Corella is local and hence great con­ flict between man and bird occurs. When the birds attack this newfound food source, it results in the death of thousands ofbirds per annum.

It is a small parrot with a variety of color patterns and a head crest. They are attractive as well as friendly. They are capable of mimicking speech, although they can be difficult to understand. These birds are good at whistling and you can teach them to sing along to tunes. Life Expectancy: 15 to 20 years with proper care, and sometimes as Cockatiels as 30 years though this is rare. In their native Australia, cockatiels are Cockatiels quarrions or weiros. They primarily live in the Cockatiels, a region of the northern part of the Cockatiels.

    AustralianAustralian ThreatenedThreatened SpeciesSpecies Carnaby’s Black-Cockatoo Calyptorhynchus latirostris Conservation Status Commonwealth: Endangered (Environment Protection and Biodiversity Conservation Act 1999) WA: ‘Specially protected fauna’ (Western Australian Wildlife Conservation Act 1950) What do they look like? This large black cockatoo (also known as the Short-billed Black-Cockatoo) has white tail panels, white cheek patches and a short bill. It lives only in southwest Australia where large-scale clearing for farming has fragmented much of its habitat, particularly mature eucalypts such as salmon gum and wandoo that have suitable hollows for nesting. Where do they live? Carnaby’s Black-Cockatoo is endemic to southwest Western Australia, extending from the Murchison River to Esperance, and inland to Coroow, Kellerberrin and Lake Cronion. Most breeding occurs in areas with an average annual rainfall of 300-750mm, typically in the Wheatbelt and Great Southern regions. For nesting, Carnaby’s Black-Cockatoos require HowHow many areare there?there? eucalypt woodland, comprising principally of salmon gum or It is difficult to know how many Carnaby’s Black-Cockatoos wandoo.

E-mail: [email protected]; [email protected] All authors contributed equally to this work ABSTRACT The Tanimbar Islands located in the Wallacea region have particularly important ornithological values due to high level of endemism. Avian researchers have carried out expeditions to Tanimbar since long time ago starting with Forbes in 1882. An iconic bird of the Tanimbar Islands is the endemic Tanimbar corella (Cacatua goffiniana). This species is considered near threatened by the IUCN, listed in CITES Appendix I, and is protected under Indonesian law. The objectives of the study were to assess bird diversity, habitat use, and association between C. goffiniana and other bird species on the Tanimbar Islands. Data were collected between 2015 and 2019 on Yamdena, Larat, Selaru, and Vaimar Island of Kepulauan Tanimbar Regency, Maluku Province.

Two species of corella, the Little Corella Cacatua sanguinea and Long-billed Corella C. tenuirostris, have been introduced into south-western Western Australia. To determine how they used the landscape, we undertook a wing-tagging study in 2012–2013 to monitor movements of individual birds. Sixty-two birds (44 Little Corellas and 18 Long-billed Corellas) were tagged and released from five sites and a total of 390 sightings was recorded over a 7-year period. There was a significant difference in the mean distances from tagging sites that corella species were sighted, with Little Corellas travelling further than Long-billed Corellas. The greatest distance from its tagging site recorded for a Little Corella was 145 km and for a Long-billed Corella was 77 km.
