Most hummingbirds die their first year, but when they've survived a full annual cycle, their life expectancy goes up dramatically. The record age of a banded ruby-throated hummingbird is 6 years, 11 months. The record age of a banded rufous hummingbird is 8 years 1 month.
Male hummingbirds, along with many other animals, have what is known as a territory. A territory is simply an area that a male occupies and chases other males away from. A female hummingbird will visit a male's territory, at which time the male performs a courtship display to try to convince the female that he is the best male around. If she likes his display, she will mate with him. If not, she moves on to another territory.

nest building, incubating, and caring for the babies herself, and a male
hummer will mate with any females that he can attract to his territory.
