Sea otters mating. The male holds the female's head or nose with his jaws during copulation. Visible scars are often present on females from this behavior. Sea otters have a polygynous mating system. Many males actively defend territories and will mate with females that inhabit their territory or seek out females in estrus if no territory is established. Males and females typically bond for the duration of estrus, or about 3 days.

Brown pelican spreads its enormous wings to slow before landing on seaside cliffs. Brown pelicans appear awkward but in fact are superb and efficient fliers, ranging far over the ocean in search of fish to dive upon. They typically nest on offshore islands and inaccessible ocean cliffs. The California race of the brown pelican holds endangered species status. In winter months, breeding adults assume a dramatic plumage.
