The Albatrosses and a Killer Whale - Essay ExampleChanges caused to the marine environment due(p) to natural as well as human reasons, as stated by Safina, have made the albatrosses vulnerable (qtd. in Sakamoto et al. 1). As mentioned by Croxall and Brooke, in recent times, studies have been carried out about the diet and foraging habits of these birds. However, little is known about how albatrosses actually locate their prey inthe open marine (qtd. in Sakamoto et al. 1). Previous studies found it difficult to follow individualbirds, and thus could not find out all about the foraging activities employed by them. This particular claim is mainly aimed at examining how albatrosses find their prey, as well as how they deal with and respond to their environment while on their foraging trips in the Southern Ocean (Sakamoto et al. 1). Four black-browed albatrosses were captured at their nest sites in Bird Island, SouthernGeorgia for the purpose of this study, and still cameras were attac hed to their backs. Three of the four birds were recaptured and the instruments retrieved. The fourth part bird could not be recaptured.The camera was equipped with depth and temperature sensors. After the recovery of the instruments, the data captured, which included image, depth and temperature, were downloaded to a PC. The environment around the study birds was studied. Other animals or birds which appeared in the images were also scrutinized. Depth data were analyzed with a behavior analysis program.
