In Beowulf, an Anglo Saxon poem, is written ” . . . craving for carrion, the dark raven shall have its say, and tell the eagle how it fared at the feast, when, competing with the wolf, it laid bare the bones of corpses.”

The Welsh Owein had a magical army of ravens. In Welsh folklore, the raven is also an omen of death. If the raven makes a choking sound, it is a portent of the death rattle. A crying raven on a church steeple will “overlook” the next house where death will occur. A raven could smell death and would hover over the area where the next victim dwelt, including animals. Ravens were heard to “laugh” when someone was about to die. Welsh witches, and the Devil, would transform themselves into ravens. Raven represents winter, because of their ability to endure the cold. My husband, who was stationed in Greenland with the Army in the 1960’s, saw only two animals the year he was there – arctic foxes and ravens!In the animal world, ravens natural enemies are the great horned owl and red tail hawk. Ravens will cooperate together and mob these bigger birds to drive them off. a b c Sabat, P. A. B. L. O. (2000). "Birds in marine and saline environments: living in dry habitats".

Yet in many cultures Raven also represents deep magic, the mystery of the unknown, death and transformation, creation, healing, wisdom, protection, and prophecy.

In a cave, north of Fort St. John, British Columbia, important discoveries were made by Dr. Knut Fladmark in 1974, then in the 1980s and again from 1990 to 1991 by Dr. Jon Driver and Dr. Fladmark. From the remains found, archaeologists have a clearer understanding of the people, environmental changes, and the animals that lived in the region, spanning thousands of years.

Raven and Crow are favorite subjects in traditional Chinese and Japanese art. I have found raven paintings by local Japanese and Chinese artists in San Francisco.Although the vast majority of archaeologists agree that ‘Paleoindian’ cultures were well-established throughout the Americas dating to the end of the last glacial period (about 12000 BC), when their ancestors first arrived across the Bering Straits, is still debated.

Once the kidneys receive blood, filtration of substances from the blood into urine takes place. The glomerular filtration rate of single nephrons in birds is low because avian glomeruli have small surface area. Through the process of reabsorption, the majority of the fluid volume and solutes are transported from the urine to the blood. Next, secretion of materials from the renal epithelia into the urine occurs. Finally, urine as the end product travels to the ureters to be excreted. The kidneys of a common raven filter about eleven times its total body water daily, and more than 95% of the filtered water is reabsorbed. Urine of birds is typically concentrated to an osmolarity that is two to three times the osmolarity of plasma. Glomerular filtration only accounts for 10% to 20% of urinary urate. Greater than 90% of urate excreted by the kidneys is derived from the process of secretion. [29] Circulation and respiration [ edit ]
