Whale Songs Humpback whales are known for their magical songs, which travel for great distances through the world's oceans. The trend of integrated primary productivity (IPP) in the Monterey Bay region closely parallels that of song occurrence (,Annual metrics for (a) humpback song occurrence; (b) integrated primary productivity (station locations in,Consistent with the increasing trend in primary productivity, krill transitioned from a strong negative anomaly in the first year, to near normal in the second year, to a strong positive anomaly in the third year (,Beyond the magnitude of primary productivity, a potentially influential factor is the extent to which primary productivity generates algal toxins that can affect marine mammal health and behavior. And we think that this is driving it trying to be novel if you're trying to of course you know display to the ladies.WALLCE: It’s possible that new whale songs are catchy for the same reason new human songs are: they’re surprising and cool.But... hold up. Humpback whale song is one of the most studied phenomena in whale research. Noad suggests that the development may be the result of “runaway selection”.Early humpbacks with complex songs were so much more successful at mating that they gained a substantial evolutionary advantage over their brethren with simpler vocalisations. Winn and B.L. This large male humpback was travelling with another whale through the islands of Tonga. This analysis pools all November through January data from the first three years of recordings (,Interannual variation in humpback song occurrence was marked by 44% and 55% increases between consecutive years (,Consideration of all hypotheses for the strong interannual trend in song occurrence requires the context of interannual variations in ecosystem conditions. 571–584. These factors include primary productivity, exposure to a neurotoxic algal compound, and forage species composition and abundance.

Upon studying the intricate vocalizations of the humpback whales, they realized that what they were hearing were fixed rhythmic patterns of repeated sound: in other words, song. Due to the sheer scale of this comment community, we are not able to give each post the same level of attention, but we have preserved this area in the interests of open debate. The arrow indicates the location of Monterey Bay National Marine Sanctuary (MBNMS). During the annual peak in song occurrence, November through January (,Values represent the percentage of recording time within each solar elevation bin during which song sessions were detected. The work is made available under the,Since first being characterized as song nearly a half century ago [,Early interpretations that humpback song occurs only in breeding habitats have yielded to a growing body of observations of humpback song occurring in feeding habitats [.The study region is the Monterey Bay National Marine Sanctuary (MBNMS), in the central California Current System (CCS;(a) The study region is along the northeast Pacific margin, in the California Current System (CCS). They have come back from the brink of extinction, thanks to international cooperation. Forage data are from spring/summer of each year and provide an indicator of the overall condition of forage species populations within the central CCS [.The region around the hydrophone from which humpback song would be detectable under different levels of background noise is characterized from received level for a sound source having a frequency (350 Hz;(a) The map represents received levels (RL) at the MARS observatory for a sound source at 10 m depth having a frequency (350 Hz;The three-year record of humpback song detection shows large seasonal and interannual variations (,Humpback song presence during the first three years of MARS recordings (black bars). Humpbacks, and possibly bowheads, sing complex songs with repeated patterns, says Michael Noad, an associate professor in the,“The thing that always gets me out of bed in the morning is the function of the song,” Noad says. The whales come here for breeding and to give birth in waters that are safe from predators such as orcas and great white sharks. So if we've got a population of whales singing off the west coast of Australia and a population singing off the east coast of course there's an entire continent in the way between those two and they can't hear each other. The abundance of humpback whales off the U.S. West Coast has increased from about 900 individuals in the early–mid 1990s to about 2,900 whales in 2014, as this species has recovered from historic whaling impacts [.Levels of song occurrence in this feeding and migratory habitat are high, occupying 9 months of the year with temporal coverage reaching as high as 86% of the time during the annual winter peak.

in: “Whales, Dolphins, and Porpoises,” K. S. Norris ed., pp. Two groups of whales, the humpback whale and the subspecies of blue whale found in the Indian Ocean, are known to produce a series of repetitious sounds at varying frequencies known as whale song. The MARS node is on Smooth Ridge (36.713°N, 122.186°W, 891 m depth). The rise of song activity leading into the breeding season is consistent with a central role in reproductive ecology, yet the prevalence of song in feeding and migratory habitats motivates further consideration of the greater spectrum of possible roles in social interaction, cultural transmission, and perception. in: “Reproduction in Whales and Dolphins: Reports to the International Whaling Commission Special Issue 6,” pp. Monthly values represent the percent of recording time during which song sessions were detected, whether from single or multiple singers (see,Monthly mean song levels show that 76% of all song occurs within one quarter of the year, November through January (,Monthly song statistics are based on data from all three years of recording (,The South Pacific analogue to the CCS is the Humboldt Current System (HCS). Aberrant songs of humpback whales (.Gaskin, D. E., 1982, “The ecology of whales and dolphins.” Heinemann: London.Gerhardt, H.
