penguins
Antarctic seabirds, with large bodies, heavy bones, and small feathers well adapted to swimming.
common murre
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
downy feathers
excellent insulators, cover chicks for the first part of their lives
contour feathers
strong, flexible, long feathers, used for flying
cliff nests
normally protected from land based predators they provide quick and easy access to feeding grounds
biosecurity plan
documented strategy for preventing the introduction of invasive species, may involve educuation of local residents, spot checks of boats, and/or trapping
Laysaan Albatross
nests in the Northern Hawaiian Islands, its feeding style has made it particularly vulnerable to plastic ingestion
Emperor penguin
only live in Antarctica, male penguin goes 2 months without eating while holding the chick egg, largest of its kind

plunge diving
a feeding strategy that involves plunging from a great height to pursuing schooling prey underwater
kleptoparasitism

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
sooty shearwaters
Despite its small size it holds the record for the worlds longest seasonal migration
