Brown pelicans preening. After wiping its long beak on the uropygial gland near the base of its tail, the pelican spreads the preen oil on feathers about its body, helping to keep them water resistant, an important protection for a bird that spends much of its life diving in the ocean for prey.

A brown pelican preening, reaching with its beak to the uropygial gland (preen gland) near the base of its tail. Preen oil from the uropygial gland is spread by the pelican's beak and back of its head to all other feathers on the pelican, helping to keep them water resistant and dry. Note the yellow throat of this individual, different than the more typical red throat.

A bull elephant seal forceably mates (copulates) with a much smaller female, often biting her into submission and using his weight to keep her from fleeing. Males may up to 5000 lbs, triple the size of females. Sandy beach rookery, winter, Central California.

Male elephant seals (bulls) rear up on their foreflippers and fight for territory and harems of females. Bull elephant seals will haul out and fight from December through March, nearly fasting the entire time as they maintain their territory and harem. They bite and tear at each other on the neck and shoulders, drawing blood and creating scars on the tough hides. Sandy beach rookery, winter, Central California.
