Royal albatrosses or diomedeidae Royal albatrosses or diomedeidae Presentation Transcript

  • NORTHERN ROYAL ALBATROSSES OR DIOMEDEIDAE A research assignment by Hannah Neilson, Room 14, 2013.
  • DIET Albatrosses mainly eat surface squid and schooling fish, but they will follow mariners’ boats in hope of dining on hand-outs or thrown over board rubbish/ garbage.
  • PHYSICAL FEATURES Royal Albatrosses have an amazing wingspan of over three meters(2m-3.4m!) Using this wingspan, an Albatross can cover up to 5000 kilometres in one journey! Albatrosses also have an amazing lifespan of up to sixty years. They weigh around nine kilograms.
  • Albatrosses weigh around nine kilograms. Albatross chicks end up weighing more than their parents while they are growing up as they have no way of losing weight while sitting in their nest. Physical Features Continued:
  • HABITAT Albatrosses can be seen around Taiaroa Head, Otago Peninsula. They can also be seen around the northern oceans, although can be seen all around New Zealand coasts.
  • BEHAVIOUR Albatrosses spend most of their time out at sea because they are hunting for food so as to survive in the wild. Albatrosses use their special tubed nostrils ( positioned at the top and slightly to each side of the bill) to remove the salt from all the water they drink when they dive after surface water squid and schooling fish. Northern Royal Albatrosses have a regular route they follow around the southern oceans
  • Behaviour Continued Mating pairs only lay one egg every two years. Young albatrosses can fly within 7-10 months of birth. They leave their birth island for 5-10 years at 9 months. Albatrosses use their formidable wingspan to ride the ocean winds without a single flap of their wings for hours on end. The sea is an albatrosses bed, as they can float on it while sleeping and not sink. This position makes them vulnerable to aquatic predators.
  • BEHAVIOUR CONTINUED Albatrosses are rarely seen on land as they prefer to remain at sea, only coming to land to breed and raise their young. It takes up to seventy-nine days for an egg to hatch after it has been laid.
  • INTERESTING FACTS Albatrosses have special tubed noses up the top and slightly to the side of their bill. They use these to remove salt from the water the bird takes in while diving for food. Albatrosses were heavily hunted for their feathers, which were used as down and in the manufacture of women’s hats.
  • INTERESTING FACTS CONTINUED Albatrosses have a special place in maritime and superstition, most memorably in Samuel Taylor Coleridge’s The Rime of The Ancient Mariner. They measure over one metre from the point of their beak to the tip of their tail. When albatrosses get tired of gliding, they have a short rest on their giant bed, the sea.
