Species of bird

The long billed corella, also known as long billed cockatoo or slender billed corella (Cacatua tenuirostris), is a cockatoo native to Australia, which is similar in appearance to the little corella. The first formal written description was by German naturalist Heinrich Kuhl in 1820. has a wingspan around 80–90 cm, and averages 567 g in weight. and can now be found in Tasmania, South Australia and southeast Queensland. A feral population resides in Perth, Western Australia as of the mid 1980s, which has conservation implications as this species may hybridize with the endangered western corella. The long billed corella is found in grassy woodlands and grasslands, including pasture, fields of agricultural crop, and urban parks. , or combined with harsh screeches. although they were formerly uncommon, and their captive population has stabilised in the last decade. This may be due to their ability to mimic words and whole sentences to near perfection. The long billed corella has been labeled the best "talker" of the Australian cockatoos, and possibly of all native Psittacines.

Long billed corellas are viewed as agricultural pests, particularly in western Victoria and Western Australia. They can cause significant crop damage, are known for tearing and playing with pieces of asphalt along roadsides, and even damaging power lines. Permits are regularly issued in Western Australia (and sometimes in Victoria) for the culling of this species. Within New South Wales, the corellas are the most common avian pest among sporting fields and golf courses, as they can dig holes in the ground up to 3 in across and 6 in deep. about 60 corellas in Adelaide, South Australia, died in a suspected case of poisoning after "falling from the sky" wailing and bleeding from their mouths. At least 57 (95%) of the 60 birds were long billed corellas, with a few short billed corellas. It was hoped that whoever poisoned them could be traced, after toxicology tests were performed (which could nevertheless take several weeks to complete); in Australia, people are required to register if they purchase poisons, according to Sarah King (founder of Casper's Bird Rescue, who witnessed the deaths). King also said that the poison was a slow release variety that takes several painful weeks to kill the bird. Additionally, the local Alexandrina council had, previously, allowed for periodic culling of short billed corellas due to crop damage, chewing on streetlights and wires, damaging infrastructure (such as buildings and sporting equipment), and unfairly outcompeting other native species of birds, insects, small mammals, and other organisms.
