Falcons: Arabian Oryx: Snakes: Falcons are small to medium-sized birds of prey related to hawks, eagles, and vultures. They usually have pointed wings and long tails. is a medium-sized antelope with a distinct shoulder bump, long, straight horns, and a tufted tail.[2] It is a bovid, and the smallest member of the genus Oryx, native to desert and steppe areas of the Arabian Peninsula. The Arabian oryx was extinct in the wild by the early 1970s, but was saved in zoos and private reserves, and was reintroduced into the wild starting in 1980. There are more than 3,000 species of snakes on the planet and they’re found everywhere except in Antarctica, Iceland, Ireland, Greenland, and New Zealand. About 600 species are venomous, and only about 200—seven percent—are able to kill or significantly wound a human. Most falcons eat small mammals. Some species hunt other birds, which they take in flight. Like hawks, most falcons have dark gray or brown backs and wings, with white undersides. The peregrine falcon is found over most of the world and is famous for hunting birds by diving down on them at 320 km/h (200 mi/h). It was nearly wiped out in North America by the use of pesticides but has since made a recovery. In some countries falcons are used in falconry. This means people catch the birds and make them hunt for them. Long ago this was a way for people to get more food but today it is a sport. The diets of the Arabian oryx consist mainly of grasses, but they eat a large variety of vegetation, including buds, herbs, fruit, tubers and root s. Herds of Arabian oryxes follow infrequent rains to eat the new plants that grow afterward. They can go several weeks without water. Almost all snakes are covered in scales and as reptiles, they’re cold blooded and must regulate their body temperature externally. Scales serve several purposes: They trap moisture in arid climates and reduce friction as the snake moves. There have been several species of snakes discovered that are mostly scaleless, but even those have scales on their bellies. Snakes also have forked tongues, which they flick in different directions to smell their surroundings. That lets them know when danger—or food—is nearby.
