<P> The hyacinth macaw (Anodorhynchus hyacinthinus), or hyacinthine macaw, is a parrot native to central and eastern South America . With a length (from the top of its head to the tip of its long pointed tail) of about 100 cm (3.3 ft) it is longer than any other species of parrot . It is the largest macaw and the largest flying parrot species, though the flightless kakapo of New Zealand can outweigh it at up to 3.5 kg . While generally easily recognized, it can be confused with the far rarer and smaller Lear's macaw . Habitat loss and the trapping of wild birds for the pet trade have taken a heavy toll on their population in the wild, so the species is classified as Vulnerable on the International Union for Conservation of Nature's Red List, and it is protected by its listing on Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). </P> <P> English physician, ornithologist, and artist John Latham first described the hyacinth macaw in 1790 under the binomial name Psittacus hyacinthinus based on a taxidermic specimen sent to England . It is one of two extant and one probably extinct species of the South American macaw genus Anodorhynchus . </P> <P> The largest parrot by length in the world, the hyacinth macaw is 100 cm (3.3 ft) long from the tip of its tail to the top of its head and weighs 1.2--1.7 kg (2.6--3.7 lb). Each wing is 388--425 mm (15.3--16.7 in) long . The tail is long and pointed . Its feathers are entirely blue, lighter above . However, the neck feathers can sometimes be slightly grey . </P> <P> The majority of the hyacinth macaw diet is nuts, from native palms, such as acuri and bocaiuva palms . They have very strong beaks for eating the kernels of hard nuts and seeds . Their strong beaks are even able to crack coconuts, the large brazil nut pods, and macadamia nuts . The birds also boast dry, smooth tongues with a bone inside them that makes them an effective tool for tapping into fruits . The acuri nut is so hard, the parrots cannot feed on it until it has passed through the digestive system of cattle . In addition, they eat fruits and other vegetable matter . The hyacinth macaw generally eats fruits, nuts, nectar, and various kinds of seeds . Also, they travel for the ripest of foods over a vast area . </P>
