摘要: We examined inter-island movements and offshore migrations of six humpback whales (Megaptera novaeangliae) tagged during March April 1995 with satellite-monitored radio tags off Kaua´i, Hawai´i. The transmitted 0.5-17 days ( x bar = 8.5 ± 2.7 days) produced 1-66 locations that met our screening criteria. Total travel distances per individual ranged from 30 to 1860 km. After criteria were applied, satellite-acquired 1.8 3.9/day for individuals (group average 2.7/day). One adult traveled 250 km O´ahu in 4 days. Another visited Penguin Bank five islands (820 km) 10 days, suggesting faster movement than had been previously thought. Three independent, parallel courses toward the upper Gulf Alaska on north-northeast headings. A female a calf was fastest: 670 4.5 (150 km/day). Two 14.7 17 an speed 110 km/day (4.5 km/h). 4200-km migration Ala...
