Egg is the reproductive body laid by the female encased in a round or oval shell. The egg consists of the thick, clear white (albumen), approximately 60% of total weight of egg, and a yellow yolk, approximately 30% of total weight of egg.he white is 87% water and 10% protein. The protein in egg whites coagulate at 150 degrees F (65 degrees C). The yolk consists of 50% water, 16% protein and 32% fat. The protein in the yolk coagulates at 158 degrees F (70 degrees C). Eggs, as well as flour, are the structural ingredients in baking.
But thatâs nothing compared to the speed of some birds. Even a common small bird like the sparrow can sail along at 50 miles per hour, while pigeons can reach 65 miles per hour, and ducks, 70 miles per hour. The fastest of all birds, and the fastest-moving living creature, however, is a small bird called the swift. Swifts can speed through the air at more than 106 miles per hour! Now thatâs swift!
G enerally birds follow the facetious advice often given to pilots -- fly low and slow.. Most cruise speeds are in the 20-to-30-mph range, with an eider duck having the fastest accurately clocked air speed of about 47 mph. bird might be able to stay aloft 6 hours at 15 mph (maximum endurance, covering 90 miles) or 5 hours at 20 mph (maximum range, covering 100 miles). Birds can also choose to maximize speed, as when being chased by a predator or racing to defend a territory. Or they can choose some compromise between speed and range.
