Wild boar are primarily nocturnal animals irrespective of sex, age, or season, although they may be more diurnal in times of food shortage.
A loon is a large, heavy bird that weighs about 9 pounds (4 kilograms). Ducks range from 15 to 24 inches & are related to swans.
Loon is a carnivore (meat-eater). Its diet is based on fish (such as gulf menhaden, perch, trout), crabs, lobsters, shrimps, mollusks and insects. Natural enemies of loons are gulls, ravens, crows, turtles, raccoons, otters, skunks and weasels. Loon is solitary bird. It occasionally gathers in small groups (of up to 20 birds) during the summer and autumn. Loons produce yodel calls to announce occupation of a territory during the breeding season. Tremolo calls (which sound like maniacal laughter) are sign of aggression.
