11 amazing facts about the Hyacinth Macaw
Wrapped in brilliant cobalt-blue plumage and standing about a metre tall from beak to tail, the Hyacinth Macaw (Anodorhynchus hyacinthinus) is one of the most striking birds on Earth. Here are eleven facts that explain why this Brazilian giant fascinates birdwatchers and conservationists alike.
1. It is the largest flying parrot in the world
At roughly one metre (about 3 ft 3 in) from head to tail tip, the Hyacinth Macaw is the longest parrot species and the largest of all macaws. Only the flightless kakapo of New Zealand outweighs it among parrots.
2. Its wingspan tops four feet
Spread wide, the wings can exceed 1.2 metres (more than four feet), giving the bird a powerful, unhurried flight across open wetland skies.
3. The beak can crack nuts that defeat a hammer
This is a palm-nut specialist. Its enormous curved beak cracks the rock-hard nuts of acuri and bocaiuva palms — a food source almost no competitor can exploit.
4. Its tongue has a bone in it
Behind that crushing beak, the dry, scaly-looking tongue contains a small bone and is used to tap and taste food with surprising delicacy.
5. It nests in just one kind of tree
In the Pantanal, pairs nest almost exclusively in cavities of the soft-cored manduvi tree (Sterculia apetala), a tight ecological link that ties breeding success to a single tree species.
6. It can live for decades
Hyacinth Macaws commonly live 30 to 50 years in the wild, and individuals in human care have passed 50 years of age.
7. Pairs raise very few chicks
Clutches hold only one or two eggs, incubation lasts about a month, and chicks do not fledge until roughly 110 days old — making the species slow to recover from any loss.
8. Its stronghold is the world's largest tropical wetland
Most of the global population lives in Brazil's Pantanal, with smaller numbers in the dry Cerrado and along the southern Amazon fringe.
9. It is not naturally aggressive — but the bite is formidable
These birds are gentle toward people by nature, yet their beak is among the most powerful of any parrot, so a bite can cause serious injury.
10. CITES gives it the strictest possible trade protection
Listed on CITES Appendix I, commercial international trade in wild Hyacinth Macaws is banned — a response to the trapping that once devastated wild numbers.
11. It is recovering, but still vulnerable
The IUCN classifies the species as Vulnerable, estimating around 4,300 mature individuals in 2021 with a declining trend. Brazil reassessed it as Endangered nationally after the 2020 Pantanal fires.
