chicken (Gallus gallus domesticus).
The term "rooster" originated in the United States as a puritan euphemism to avoid the sexual connotation of the original English "cock", and is widely used throughout North America. "Roosting" is the action of perching aloft to sleep at night, which is done by both sexes.
Sperm transfer occurs by cloacal contact between the male and female, in a maneuver known as the “cloacal kiss”. The rooster is polygamous, but cannot guard several nests of eggs at once. He guards the general area where his hens are nesting, and attacks other roosters that enter his territory. During the daytime, a rooster often sits on a high perch, usually 0.9 to 1.5 m (3 to 5 feet) off the ground, to serve as a lookout for his group (hence the term "rooster"). He sounds a distinctive alarm call if predators are nearby and will frequently crow to assert his territory." - (en.wikipedia.org 01.03.2020)
