The hyacinth macaw is the world's largest parrot by length, recovering in the Brazilian Pantanal through nest box schemes and anti-poaching, providing a welfare model for large parrot conservation.
Illegal trapping for the pet trade involves capture methods causing injury and high mortality in transit. Habitat loss in the Cerrado and Pantanal removes both nesting sites and Acuri palm food plants. Nest box provision by the Hyacinth Macaw Institute has directly improved welfare-relevant breeding success.
