Macaws, Macaw Pictures, Macaw Facts Macaws are beautiful, brilliantly colored members of the parrot family. Many macaws have vibrant plumage. The coloring is suited to life in Central and South American rain forests, with their green canopies and colorful fruits and flowers. The birds boast large, powerful beaks that easily crack nuts and seeds, while their dry, scaly tongues have a bone inside them that makes them an effective tool for tapping into fruits. Macaws also have gripping toes that they use to latch onto branches and to grab, hold, and examine items. The birds sport graceful tails that are typically very long.

Great black hawk - WOW.com The great black hawk (Buteogallus urubitinga) is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and Old World vultures. The great black hawk is a resident breeding bird in the tropical New World, from Mexico through Central America to Peru, Tobago and northern Argentina.

It builds a large stick nest in a tree, and usually lays one dark-blotched whitish egg.
Acceleration Formula Acceleration is a measure of how quickly the velocity of an object changes. So, the acceleration is the change in the velocity, divided by the time. Acceleration has a magnitude (a value) and a direction. The direction of the acceleration does not have to be the same as the direction of the velocity. The units for acceleration are meters per second squared (m/s2). a = acceleration (m/s2) Red-tailed Hawk, Identification, All About Birds - Cornell Lab of Ornithology Similar Species The first step with identifying any hawk is to use its size and shape to decide what type you're looking at. Is it one of the three main groups: buteo, accipiter, or falcon? Buteos have broad, rounded wings and short, wide tails, and you often see them soaring without flapping. Red-shouldered Hawks, another common buteo, tend to be smaller than Red-tails with a banded tail and warm brown barring below. Swainson's Hawk has a dark trailing edge to the underside of the wing, and a dark chest.
