These macaws frequently travel together in small flocks of 1–8 pairs, and loudly call to one another.
Macaw pairs remained bonded.
In the wild, macaws often flock to mountains of clay known as “macaw licks.”
When disturbed, these bright birds screech loudly and circle overhead with their long tails streaming.
Macaws are playful and inquisitive and are able to mimic human vocalizations very well.
Macaws are able to reach flight speeds of up to 56 kph (35 mph).
Macaws eat palm nuts only after the nuts have passed through the digestive system of a cow.
Ecology and Conservation.
In the course of daily feeding, macaws allow plenty of seeds (while eating, as well as in their droppings) to fall to the forest floor, thus regenerating much of the forest growth.
Highly prized as pets, they are listed on CITES because of over-collection for the pet trade and excessive habitat loss. Unfortunately, only about 2,500–5,000 exist in the wild today. Only domestically hatched birds should be considered for pets. Hyacinths in the home are large, loud, and destructive so great thought should accompany this decision.
