The average normal body temperature is generally accepted as 98.6Â°F (37Â°C). Some studies have shown that the normal body temperature can have a wide range, from 97Â°F (36.1Â°C) to 99Â°F (37.2Â°C). A temperature over 100.4Â°F (38Â°C) usually means you have a fever caused by an infection or illness.
The neo-Gothic Swallow's Nest castle perches 130 feet (40 meters) above the Black Sea near Yalta in southern Ukraine.
Both members of the pair build the nest--a mass of mud, straw, feathers, and sticks. Barn Swallow nests are relatively untidy. Both members of the pair incubate the four to five eggs for 12 to 17 days, and both feed the young. The young leave the nest 20 to 21 days after hatching.
