It should be pointed out that Mediums are actually Greaters.
The Eleanora is generally referred to as a Medium
Sulphur-crest. There are four species of Greater Sulfur-crests
(Cacatua galerita). The Lessers are a completely different
species (Cacatus sulphurea). Actually, there are five
subspecies of them, all from the Indonsian Islands.
Here are some differences in the Greaters but in many cases,
an amateur cannot tell the differences.
Greater Sulfer Cockatoo Description
Four subspecies: which differ mainly in size 15-20".
C. Galerita Galerita - plumage is mostly white; forward
curving narrow yellow crest; black beak and feet; ear patches
are yellowish; and the underside of the wings and tail
feathers are yellow.
C. Galerita Fitzroyi - similar to the nominate race Galerita
Galerita but has more yellow on the ear patches and the eye
ring is pale blue and the beak is broader.
C. Galerita Triton - lacks the yellow on the cheeks of the
nominate race and has blue eye rings. The crest is shorter and
C. Galerita Eleonora - similar to the Triton subspecies but
the beak is smaller and narrower. Crest has a flip to the end
like the nominate race. (a.k.a. Medium Sulphur-crested Cockatoo)
Galerita Galerita - 20 "
Fitzroyi - 18"
Triton - 17"
Eleonora - 16"
