Sulphur crested cockatoo, National Zoological Park, Delhi
These guys are smaller versions of their close cousins, the Sulphur Crested Cockatoo. This species
includes the subspecies Citron Crested, or just Citron Cockatoo, which is similar in looks but
larger (15") and has a deeper colored crest and distinct cheek patch, and the small Timor Cockatoo,
which isn't very common. The "standard" Lesser Sulphur is about 13" long with a yellow crest and
cheek patch. They have somewhat more independant personalities than your standard cockatoo, and
can be a bit more "one-persony", but otherwise are basically typical. They range from about $500-
$800 from a breeder, around $1,000 from a pet shop.
