Hyacinth macaw
Summary
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 one meter it is longer than any other species of parrot. It is the largest macaw and the largest flying parrot species; the flightless kākāpō of New Zealand outweighs it at up to 3.5 kg. While generally easily recognized, it could be confused with the 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).
English physician, ornithologist, and artist John Latham first described the hyacinth macaw in 1790 under the binomial name Psittacus hyacinthinus. Tony Pittman in 2000 hypothesized that although the illustration in this work appears to be of an actual hyacinthine macaw, Latham's description of the length of the bird might mean he had measured a specimen of Lear's macaw instead. However, Latham's description was based on a taxidermic specimen, which was the only one Latham knew to exist up until 1822. It was prepared from a living animal originally belonging to Lord Orford, and given to the land agent Parkinson for display in the Leverian Museum after it died.
Nonetheless, Latham mentions another bird, which he calls the 'blue maccaw', supposedly the same size. This blue macaw was already described in Latham's 1781 volume of his A general synopsis of birds as merely a variety of the blue and yellow macaw, and was previously figured in the work of Mathurin Jacques Brisson (1760), Patrick Browne (1756) and Eleazar Albin (1738) as a macaw found in Jamaica. Albin, Browne and Brisson all reference even older authors and state the bird also occurs on the mainland, and Albin states this bird is the female version of the scarlet macaw.
