While the bird itself isn’t particularly unique, this hybrid solidly proves that at least some cockatoo hybrids are fertile. Although it looks similar to a pure little corella, having white plumage with yellow underwings, a bare eye, and reddish lore, it also has a gray beak and small yellow-orange crest feathers. It is 50% citron-crested
A somewhat uncommon hybrid that is rarely identified. It is believed that many citron-crested cockatoos available today have sulphur-crested or yellow-crested blood. Sulphur-crested x citron-crested hybrids are almost fully white with yellow underwing and tail feathers, as well as a yellow-orange crest. They are much smaller than pure sulphurs and have a more golden crest
Arguably the most common (purposeful) white cockatoo hybrid in the world, sulphur-crested x umbrella crosses tend to be an even split between both parents. Their plumage is almost fully white, only broken by yellow crest, underwing, and tail feathers. Such crests tend to be lemon-yellow with thicker, slightly whitish feathers. While some sunbrellas may have
A large hybrid with whitish plumage and yellow crest feathers washed with a slight pink. This hybrid’s name, “Moltri cockatoo”, is only applied to hybrids whose sulphur-crested parent was a triton subspecies. All other hybrids are simply known as Moluccan x sulphur-crested cockatoos. These birds are somewhat rare despite how common both species are.
An uncommon hybrid that was first reported in 1966 at the Keston Zoo. Major Mitchell’s x sulphur-crested cockatoos are very similar in appearance to citron-crested x Major Mitchell’s, though with a somewhat larger size and with a brighter yellow crest. While some of these hybrids may have somewhat faded yellow-orange ears, these vary from bird
A hybrid that has been documented numerous times yet remains extremely rare in captivity. Although the most well-known picture was taken in 2010, the first photo of such a hybrid was taken in 2004 during a research study (Centre for Environmental Management, University of Ballarat). Long-billed x sulphur-crested cockatoos have white plumage with a small
A somewhat uncommon hybrid that was first recorded in captivity in 1976. Little corella x sulphur-crested cockatoos have white plumage with a faded yellow-orange lore, a yellow-tipped crest, a grey beak, and a wrinkled patch of skin under each eyes. These hybrids are mostly observed in the wild and have been noted as being somewhat
Sulfin cockatoos are white birds with a yellow-orange lore and pale yellow underwing and tail markings. Their medium-length crest feathers are yellowish at the tip with a thicker white base. These hybrids are similar to goffers cockatoos (goffin’s x sulphur-crested), but are much larger in size.
The first captive galah and sulphur-crested hybrid was born in 1912 from a liberty pair of cockatoos. The parents were free to fly about the property of R. Cosgrave and chose to nest in one of his walnut trees. Their single chick became the very first cockatoo hybrid bred in captivity, though such birds had
Like other blue-eyed hybrids, blue-eyed x sulphur-crested cockatoos are most commonly found in Asia due to the prevalence of both species in this region. The pictured individual was bred from a greater sulphur-crested cockatoo (galerita), further increasing its size. Aside from this, they only differ from pure sulphurs with their bluish eyes and somewhat Moluccan-like
