Document Summary
Ethology: the scientific and objective study of animal behavior. Sensory ecology: the study of how organisms acquire, process, and respond to information from their environment. Foraging ecology: the study of food searching behavior in response to the environment where the organism lives. Umwelt: the perceptual world in which an organism exists and acts as a subject. Long distance foragers on patchily distributed resources. Nearly half (46. 5%) are threatened or endangered. They have a really good sense of smell. An identifiable biogenic odor cue in this featureless environment: dms. Dimethyl sulfide (dms) is predictably elevated where birds tend to forage. Tested plastic placed in the ocean for sulfur- tested positive. Reacted to the plastic odor and the food odor the same. Did not react to plain plastic smell. Temporary threshold shift: a temporary, involuntary loss in hearing sensitivity after an acute exposure to a powerful sound.
