Does a buzzard have a rectum? Trey?


The Buzzard excreets from an gland just beneath its beak where the faeces slowly seeps out between 1 - 4 hours.

Birds of prey, also known as raptors, are birds that hunt invertebrates and vertebrates including other birds. The term "raptor" is derived from the Latin word rapere (meaning to seize or take by force). They are characterized by keen vision that allows them to detect prey during flight and powerful talons and beaks. Because of their predatory nature they face distinct conservation concerns. In most cases, the females are larger than the males.

Digestion is the mechanical and chemical breakdown of food into smaller components that are more easily absorbed into a blood stream, for instance. Digestion is a form of catabolism: a breakdown of large food molecules to smaller ones.

In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication, a form of mechanical digestion, and the wetting contact of saliva. Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food. After undergoing mastication and starch digestion, the food will be in the form of a small, round slurry mass called a bolus. It will then travel down the esophagus and into the stomach by the action of peristalsis. Gastric juice in the stomach starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. As these two chemicals may damage the stomach wall, mucus is secreted by the stomach, providing a slimy layer that acts as a shield against the damaging effects of the chemicals. At the same time protein digestion is occurring, mechanical mixing occurs by peristalsis, which is waves of muscular contractions that move along the stomach wall. This allows the mass of food to further mix with the digestive enzymes.

A petroleum seep is a place where natural liquid or gaseous hydrocarbons escape to the earth's atmosphere and surface, normally under low pressure or flow. Seeps generally occur above either terrestrial or offshore petroleum accumulation structures. The hydrocarbons may escape along geological layers, or across them through fractures and fissures in the rock, or directly from an outcrop of oil-bearing rock.

Petroleum seeps are quite common in such areas of the world and have been known and exploited by mankind since paleolithic times. Natural products associated with these seeps include bitumen, pitch, asphalt and tar. The occurrence of petroleum was often included in location names that developed; these locations are also associated with early exploitation as well as scientific and technological developments, which have grown into the petroleum industry.
