Little Corella
Cacatua sanguinea
John Gould was the first to describe the species, in 1843.
Cacatua is based on the Malay name for cockatoo, which refers to the large bill; sanguinea is derived from the Latin sanguineus (bloody), a reference to the blood-stained appearance of the feathers on the head and neck.
