Their sense of smell is thought to be poor. But their vision and tactile sense are excellent. Military macaws roost in large groups and make regular morning and evening flights to and from feeding grounds. They spend much of their time in treetops. At the approach of danger they rise into the air screeching loudly.
Macaws live in flocks in the wild and are intensely social birds, mating for life.
They are extremely noisy birds which have harsh, unmelodic voices. Active during the day, many species of macaws will roost communally at night. This provides them with safety from predators. In the wild, the Military macaw's diet consists of seeds, fruits, nuts and some vegetable matter. In the zoo, they are fed commercial parrot pellets, fresh fruit in season, small amounts of seeds and nuts, and vitamins.
