What is a seabird?
Of all the species found in Australia only 4% are classified as seabirds . These birds spend most of their time out at sea (often only coming onto land to breed). Feed predominantly from the ocean and drink seawater. They have the ability to desalinate water through salt glands at the back of their skull and then get rid of the excess salt by letting it run down their nasal passages. Generally only lay one egg per season, some species two.
