Hyacinth Macaw Bird is the largest species of parrot in the world. This bird looks so striking with its blue color. Unfortunately, the population of Hyacinth Macaw birds began to decline in recent years. Now there are only less than 5,000 Hyacinth Macaw birds in the world. This is due to the widespread poaching of wildlife. However, at this time the Hyacinth Macaw birds can be found in the northern Brazilian prairie area.
