Hyacinth Macaw
As we’ve mentioned, macaws are some of the most colorful birds in the Amazon. The Hyacinth macaw is the world’s longest parrot, with a wingspan of 4 to 5 feet. They have a yellow patch of skin beside the lower bill and bare yellow eye-ring. If you’re lucky, you’ll spot their gorgeous cobalt blue feathers soaring through the sky. Most of them live in Brazil. One of its most striking features is that it seems to have a perpetual grin, thanks to its yellow feathers near its beak (One Earth).
