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.
These adaptations for diving come with a cost, however. The rearward placement of the feet, while great for diving, makes these ducks awkward on land. They are better off than grebes or loons, but much less able than, say, pintails, to walk from pond to pond with ducklings in tow.
