Aura (6) - Cetacean Songs For The Whales (CD)

Whales from non-overlapping regions sing entirely different songs. As the song evolves, it appears that old patterns are not revisited. Humpback whales may also make stand-alone sounds that do not form part of a song, particularly during courtship rituals. Humpbacks generally feed cooperatively by gathering in groups, swimming underneath shoals of fish and all lunging up vertically through the fish and out of the water together.

Prior to these lunges, whales make their feeding call. The exact purpose of the call is not known. Some scientists have proposed that humpback whale songs may serve an echolocative purpose, [29] but this has been subject to disagreement. Humpback whales have also been found to make a range of other social sounds to communicate such as "grunts", "groans", "thwops", "snorts" and "barks".

Most baleen whales make sounds at about 15—20 hertz. There is disagreement in the scientific community regarding the uniqueness of the whale's vocalization [34] and whether it is a member of a hybrid whale [34] such as the well documented Blue and Fin Whale hybrids. In , researchers found that blue whale song has been deepening in its tonal frequency since the s. Short range calls are reported during social and resting periods while long range are more commonly reported during foraging and feeding.

Most other whales and dolphins produce sounds of varying degrees of complexity. Of particular interest is the Beluga the "sea canary" which produces an immense variety of whistles, clicks and pulses. Researchers use hydrophones often adapted from their original military use in tracking submarines to ascertain the exact location of the origin of whale noises.

Christopher Clark of Cornell University conducted using military data showed that whale noises travel for thousands of kilometres. An important finding is that whales, in a process called the Lombard effect , adjust their song to compensate for background noise pollution.

Prior to the introduction of human noise production, Clark says the noises may have travelled right from one side of an ocean to the other, agreeing with a thirty-year-old concept blaming large-scale shipping. Environmentalists fear that such boat activity is putting undue stress on the animals as well as making it difficult to find a mate. In the past decade, many effective automated methods, such as signal processing, data mining, and machine learning techniques have been developed to detect and classify whale vocalizations.

Van; Jeffress, Jennifer A. Journal of Experimental Marine Biology and Ecology. Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of near threatened and least concern categories:. Sirenia is an order of fully aquatic, herbivorous mammals that inhabit rivers, estuaries, coastal marine waters, swamps, and marine wetlands. All four species are endangered. The order Pilosa is extant only in the Americas and includes the anteaters , sloths , and tamanduas.

The order Primates contains humans and their closest relatives: lemurs , lorisoids , tarsiers , monkeys , and apes. All the non-human Panamanian primates are New World monkeys. They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing. The lagomorphs comprise two families, Leporidae hares and rabbits , and Ochotonidae pikas. Though they can resemble rodents , and were classified as a superfamily in that order until the early 20th century, they have since been considered a separate order.

They differ from rodents in a number of physical characteristics, such as having four incisors in the upper jaw rather than two. Eulipotyphlans are insectivorous mammals. Email Address. Sign In. A sonar model for humpback whale song Abstract: Humpback whales summer at high latitudes where they feed and winter at low latitudes where they aggregate for breeding. While on the breeding grounds in Hawaii, male humpbacks space themselves and "sing" the long "songs" that have fascinated scientists and poets.

Female humpbacks are outnumbered by males and generally ignore or avoid singing males; however, singers often abruptly stop singing and then swim quickly toward distant nonvocalizing whales.
