One among the most rare of the beautiful parrot family is the anaca
(Derotypus coronatus). It is of a green colour, and at the back of its
head rises a hood of red feathers bordered with blue, which it can
elevate or depress at pleasure. It is the only American parrot which
resembles the cockatoo of Australia. It is of a solemn, morose, and
irritable disposition. The natives often keep the bird in the house for
the purpose of seeing the irascible creature expand its beautiful
feathers, which it readily does when excited. The crest is something
like that of a harpy eagle. It is known also as the hawk-headed parrot.
