This species of Cockatoo feeds on seeds, fruits and nuts. They break away from their flocks on the onset of the breeding season in spring. Many pairs roost close to their nests, whilst some roost in tall Coconut trees of deserted beaches. Normally two eggs are laid. These hatch after 24 days. IUCN categorizes this species as critically endangered. They were found in plenty 50 years ago, but their numbers have greatly fallen. Today, 80% of its population has been lost and it is estimated that there are between 1000 and 4000 Philippine Cockatoos. Red-vented Cockatoo Threats There are two main reasons for the radical decline in the number of Philippine Cockatoos – (1) pet trade, and (2) destruction of lowland forest habitat. The former is a bigger problem than the latter. This species is now classified under the C.I.T.E.S. Appendix 1 that bans the trade (unless permitted in exceptional circumstances) of the species. Red-vented Cockatoo Short-billed Black Cockatoo Distribution Habitat These Cockatoos are endemic to South-West Western Australia between the Murchison River and Esperance, and inland up to Coroow, Kellerberrin and Lake Cronion. Breeding occurs only in areas with an average annual rainfall of 11 - 30 inches (30 - 75 cm). These birds build their nests in Eucalypt woodlands, on Salmon gum or Wandoo trees. ubfamily: SScientific Name: Body Length: Weight: Lifespan: Other Common Name: Calyptorhynchinae Calyptorhynchus latirostris From 21 to 24 inches (55 - 60 cm) From 1 to 2 pounds (570 - 870 gm) Normally 40 - 50 years Carnaby's Black Cockatoo Physical Description Diet Conservation Status The Short-billed Black Cockaoo has a predominantly black plumage with white tail panels. It has white patches on its cheek and, as its name suggests, a short beak. These birds are gregarious and live as pairs or in small groups. The Short-billed Black Cockatoo population has declined by over 50% in the last 45 years. They are, therefore, listed as endangered by the Action Plan for Australian Birds 2000. It hasn’t been estimated how many of this species survive, but it is known that they don’t breed in a third of the former breeding sites in the wheat belt. Behavior Short-billed Black Cockatoos feed in Eucalypt woodlands and Kwongan heaths, on seeds of Banksias, Hakeas, Grevilleas and Eucalypts. Short-billed Black Cockatoo Threats There are a number of threats facing this species, including loss of habitat, loss of food resources due to urban development and poaching. Habitat suitable for breeding and feeding have been cleared. Nest hollows are used as firewood. This species also faces competition for hollows from other species such as the Galah. These birds are also illegally poached for their young ones and their eggs. Snippets Bonded for life: These birds display strong bond with their partners throughout their adult life. Male Carnaby's Black Cockatoos feed the female during the incubation period. They are even known to fly over 7.4 miles (12 km) to ensure she gets the food she needs during nesting. Short-billed Black Cockatoo Subspecies Sulphur-crested Cockatoos are divided into two broad classifications - Greater Sulphur-crested Cockatoos and Lesser Sulphur-crested Cockatoos. These large cockatoos make very loving pets but require lots of interaction and attention. They live long and are very affectionate. You can train them to talk and perform tricks. |
