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.
Although stifftails, pochards, and sea ducks all dive for food, there are as many differences among them as similarities. Scaup, canvasbacks, redheads, ring-necked ducks, and their cousins elsewhere around the world demonstrate their relatedness by traits other than diving.
