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.
Doek is Dutch for cloth, which was evolved into the English word duck in reference to sail canvas. Duck was typically made from cotton or linen (flax), with some use of hemp. These natural fibers have poor resistance to rot, UV light and water absorption. Linen is stronger, but cotton is lighter. Linen was the traditional fiber of sails until it was supplanted by cotton during the 19th century.
