Aggressive behavior between humpback whales (Megaptera novaeangliae) wintering in Hawaiian waters
Humpback whales (Megaptera novaeangliae) wintering in Hawaiian waters engage in strenuous aggression toward con-specifics. The social context and sex of individuals involved suggest that aggression… Expand
Migratory movement and population structure of humpback whales (Megaptera novaeanglieae) in the central and eastern North Pacific
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… Expand
Movements and Population Structure of Humpback Whales in the North Pacific
Despite the extensive use of photographic identification methods to investigate humpback whales in the North Pacific, few quantitative analyses have been conducted. We report on a comprehensive… Expand
Underwater frequency discrimination in the bottlenosed dolphin (1-140 kHz) and the human (1-8 kHz).
Frequency difference limens (DLs) were obtained for frequencies (F) from 1 to 140 kHz for the bottlenosed dolphin, Tursiops truncatus (Montagu), and from 1 to 8 kHz for two human subjects tested… Expand
Reproductive histories of female humpback whales Megaptera novaeangliae in the North Pacific
Reproductive histories of indnldually identified, female humpback whales were documented on both the summering and wintering grounds of an endangered but currently unexploited population. Interbirth… Expand

A vertical array of five hydrophones was used to measure the acoustic field in the vertical plane of singing humpback whales. Once a singer was located, two swimmers with snorkel gear were deployed… Expand
Migratory Timing of Humpback Whales ( Megaptera novaeangliae ) in the Central North Pacific Varies with Age, Sex and Reproductive Status
Humpback whales migrate seasonally between high-latitude summer feeding grounds and low-latitude winter breeding grounds. Identification photographs of humpback whales were collected in the Hawaiian… Expand
Humpback whales in the Hawaiian breeding waters: Population and pod characteristics.
Aerial, shipboard, and underwater observations were made during Spring 1976 of the population of humpback whales, Megaptera no1•aeangliae, breeding in Hawaiian waters. Animals were found around all… Expand
Estimating the mortality rate of humpback whale calves in the central North Pacific Ocean
Sighting histories of individually identified female humpback whales (Megaptera novaeangliae) in their win- ter and summer ranges were used to investigate mortality of North Pacific humpback whale… Expand
Responses of wintering humpback whales (Megaptera novaeangliae) to playback of recordings of winter and summer vocalizations and of synthetic sound
SummaryThree natural sounds and one synthetic sound were played back to humpback whales during their 1985 and 1986 winter residency in Hawaiian waters. Playback was conducted from a vessel positioned… Expand
