Across the Open Ocean: The Plight of the Laysan Albatross
Transcript of Across the Open Ocean: The Plight of the Laysan Albatross
They all nest at sixteen sites in the Pacific Ocean
99% of these birds nest on the Northwestern Hawaiian islands
IUCN lists the Laysan albatross as near threatened.
There are two main threats to the Laysan albatross: Plastic pollution and the longline fishing industry Across the Open Ocean-The Plight of the Laysan Albatross Most of the Earth’s surface is water
We need water to survive
Scientists estimate that 2.2 million species live in the water
Personal Interest What we do on land affects the Laysan albatross! Satellite telemetry
Be aware of where albatrosses live
Eat seafood from sustainable fisheries that do not use longline fishing
Recycle Telemetry tells us where albatrosses and fisheries overlap!
Telemetry tells us where albatrosses forage! Maps like this are produced by tracking an albatross using satellite telemetry and then mapping it.
Maps like this show us where albatrosses overlap with the fishing industry, and show where the highest amounts of bycatch, or animals caught incidentally while fishing for other species, through longline fishing- one of the main threats to albatross conservation, may occur. Maps like this (Young, et al., 2009) show us the relationship of nesting sites of the Laysan albatross to the gyres. This study showed that birds nesting at Kure Atoll foraged in the Western Garbage Patch and consumed 10 times the amount of plastic as birds nesting at Oahu. What can we do? Most plastic pollution starts on land!
Americans buy 4 billion gallons of water in plastic bottles!
2, 000, 000 plastic bottles are used in the US every five minutes!
93% of plastic bottles are not recycled!
Water bottles discarded in the US can circle the Earth 5 times! Bibliography: Alsop, F. (2001). Birds of North America. New York: DK.

Proceedings of the Royal Society B: Biological Sciences, 278(1722), 3191-3200. Telemetry, or radio tagging, is a non-invasive, remote observation technology. In these studies, a light, noninvasive transmitter or tag is affixed to the animal being observed. These transmitters or tags take the form of either a collar, leg band, or otherwise glued to the animal. These tags, in combination with a receiver, collect data about the animal, such as location.
