The California Brown Pelican will try and find mate every spring. Males "facial-feathers" turn bright colors and they build a nest on the ground or in a tree to lure in a female. If he successfully finds a mate, they will try to create offspring. Females usually lay three eggs. If this is the females first gestation period, she will only lay two eggs. After a while, she can produce four eggs at a time. California Brown Pelicans don't mate for life, but both parents take turns warming the eggs. Once the eggs hatch, both parents feed and protect them. The first 10 days of a baby California Brown Pelican's life depends on their parents.
