“…These data indicate that humpback whales segregate during the summer in several geographically-isolated feeding regions of the North Atlantic but congregate during winter on the Silver and Navidad Banks near Puerto Rico (Katona & Whitehead 1981, Whitehead 1982, Martin et al 1984. Some North Atlantic humpback whales also winter near the Cape Verde Islands off Africa, but this group is not well documented (Winn et al 1981). No systematic differences in the coloration of North Atlantic humpback whales are reported (True 1904).…”

“…Payne & Guinee (1983) conclude that the analysis of song structure provides an accessible method of delineating stocks or reproductively-isolated groups of humpback whales. However, neither Winn et al (1981) nor Payne & Guinee (1983) demonstrate geographic variation in the songs of different sub-populations of humpback whales in the same ocean, only differences in the songs of populations-in different oceans. Until differences between the songs of sub-populations are found, the usefulness of this method remains in question.…”

“…Further photographic data from Mexico WIU be necessary to determine, with confidence, the extent of exchange among wintering grounds. Winn et al (1981) and Payne & Guinee (1983) have found that the structure of humpback whale songs from Hawaii and Mexico is essentially identical in a given year, but clearly different from the structure of songs shared by whales from other oceans. Because humpback whale song changes, to some degree, from year to year (Winn & Winn 1978, whales that travel to Hawaii and Mexico presumably must be in acoustic contact at some point to learn the new song.…”

Photographs of individually identified humpback whales Megaptera novaeangliae were collected in regions throughout the central and eastern North Pacific during the years 1977 to 1983. A comparison of these photographs revealed extensive movement between seasonal habitats. Whales found wintering near Hawaii traveled to summer feeding regions throughout the coastal waters of Alaska. Whales wintering near Mexico were found in Alaskan feeding regions and near the Farallon Islands off central California. I-lttle exchange was found between the 2 wintering grounds or among the 5 summering grounds studied. Fidelity to a given feeding region was demonstrated by a high proportion of migratory return. Evidence of fidelity to a given wintering ground was less conclusive. The coloration of humpback whale flukes showed a longitudinal cline across the 5 feeding regions. Flukes of whales from the easternmost feeding regions were, on average, darker than those from the westernmost feeding regions. Whales in Hawaii and Mexico were similar in fluke coloration and the average coloration on both wintering grounds was intermediate between the extremes of the feeding regions. We propose that humpback whales in the eastern and central North Pacific form a single 'structured stock' consisting of several geographically-isolated 'feeding herds' which intermingle on 1 or more wintering grounds. Mark-recapture analyses of resightlng data indicate that the Hawaiian wintering congregation is 4 to 6 times larger than the southeastern Alaska feeding herd. Within a structured stock, sets of whales interact with different probabilities in each seasonal habitat. This, in turn, has important implications for the social organization and management of these whales.

Acoustic recordings of baleen whale calls were analysed for the calendar year 1997 from a pair of fixed hydrophones located 5 km east of Great Barrier Island, New Zealand. The primary goal of the study was to examine blue whale seasonally and song type as part of a larger worldwide study. Calls were recorded from blue whales of two song types, fin whales, humpback whales, Bryde's whales, and of two unknown call types, each probably produced by Bryde's whales. The peak of calling density was May through September for the blue, fin, and humpback whales. The known Bryde's whale calls occurred year-round and the probable Bryde's whale calls occurred from May through December. Blue whale songs of a type so far known only from New Zealand waters were detected within 2 km of shore and occurred four times from June to December, whereas the Southern Ocean blue whale songs were detected only further offshore in mid-winter. Bryde's whale calls were the most abundant type and often occurred near the hydrophones. These data provide a baseline from which future recordings from the same hydrophones could be compared.

“…Previous investigations revealed that geographically isolated populations produce distinctive songs. Humpback whales from different ocean basins sing very different songs, whereas whales of the same ocean basin sing similar songs, even though they may be separated by a considerable distance (Winn et al, 1981;Helweg et al, 1998). Of the songs studied in the Southern Hemisphere, the majority have been collected from wintering areas in the Southwestern Pacific ocean basin (Cato, 1991;Mednis, 1991;Helweg et al, 1998 …”
