Blue-and-Yellow Macaw, One of the most recognizable of the #Macaw, this bird is popular as a pet throughout the world thanks to their ability to talk and bond with humans. wild populations are found in South America and ranging as far north as #Florida. The Blue-and-yellow Macaw is not a light bird so the primary feathers have to be long and strong in order for the bird to be capable of sustaining flight. The Macaw's flight feathers are shaped with a shorter leading edge and a longer trailing edge. The leading edge is curved and forces air over the upper surface of the #wing creating lift during flight.
