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.
Loons and grebes, which nest on lakes but winter at sea, are usually categorized as water birds, not seabirds. Although there are a number of sea ducks in the family Anatidae that are truly marine in the winter, by convention they are usually excluded from the seabird grouping.
