Little Corellas have been increasing in number locally over the past several
years. Probably pushing the boundaries of the word to call them common but
then it depends on how the word is used.
Here is the text from the 21 year GBS Report:
Little Corella Cacatua sanguinea
The status of this species is unclear, its natural range is semi-arid inland
Australia. There are unexpected populations appearing in many areas of
Australia, even coastal regions. The monthly pattern of abundance appears
quite smooth. This is suggestive of natural processes rather than random
escapes. The low in October is typical of the pattern shown by other
parrots. From October it increases smoothly to a peak in January then
declines. The January peak is unique among parrots. However any credence to
this result should wait until there is further evidence, as it is largely
based on few years. In recent years it has become quite widespread,
occurring at many sites. Sometimes in large flocks of up to 40 birds. One
record of birds inspecting hollow in Year 14 at Site 225 and a dependent
young February Year 19 at Site 60.
