Marine Biology - Seabirds
Antarctic seabirds, with large bodies, heavy bones, and small feathers well adapted to swimming.
Arctic swimming, diving birds. The migrate long distances and nest in coastal cliffs. The last year has seen significant die offs of this bird.
sea bird hearts
Four chambers rather than three.
sea bird bones
heavier and denser than not seabirds
excellent insulators, cover chicks for the first part of their lives
strong, flexible, long feathers, used for flying
normally protected from land based predators they provide quick and easy access to feeding grounds
documented strategy for preventing the introduction of invasive species, may involve educuation of local residents, spot checks of boats, and/or trapping
nests in the Northern Hawaiian Islands, its feeding style has made it particularly vulnerable to plastic ingestion
only live in Antarctica, male penguin goes 2 months without eating while holding the chick egg, largest of its kind
sea bird clutches
small, typically just 1 to 3 eggs
March of the Penguins
a movie documenting the long migration of emperor penguins, taken to find breeding habitat on fast ice, far away from predators
the act of grooming and maintaining feathers, it keeps feathers coated in protective oil, which in-turn keeps them dry
a feeding strategy that involves pursuing prey underwater while swimming
a feeding strategy that involves plunging from a great height to pursuing schooling prey underwater
birds stealing food from other bids, frigate birds use this strategy
Yellow eyes and yellow band runs through each eye, most endangered of the penguins
counter current heat exchange
The transfer of heat from blood moving in one direction to blood moving in the opposite direction.
a burrow nesting seabird, their localized life style makes them an ideal study subject for scientists interested in ecosystem changes
Despite its small size it holds the record for the worlds longest seasonal migration
