Some whale migration routes are known to exceed 5,000 miles between feeding and breeding grounds, and humpback whales in particular have some of the longest migrations of any mammal.
The remote Portuguese archipelago, consisting of nine volcanic islands about 900 miles west of Lisbon, lies in the North Atlantic Ocean, putting it on the migration route of several whale species ...
Though some whale migration routes are known to exceed 8,000km between feeding and breeding grounds, such long-distance movement between longitudes is “atypical”, scientists say.
Whales Alive (29 July 2009) South Pacific Whale Research Consortium (29 July 2009) Although most of the Signatories have only small land areas, they are of the highest importance since they are surrounded by huge Exclusive Economic Zones, covering millions of square kilometres of sea, which the cetaceans use as migration routes.
Their migration patterns are among the longest of any mammal, spanning over 10,000 miles (16,100 km). Blue whales also use the Southern California Bight as a part of their migratory routes. They leave Baja California by early summer, and are usually present in the Southern California Bight in June.
Blue whales – whose migration routes were previously unknown – were located by air, after some of the animals had been given temporary radio tags. The camera team spent three years on standby, using a microlight to land on the water nearby when they finally caught up with the creatures in the Gulf of California .
In general, blue whale populations migrate between their summer feeding areas near the poles and their winter breeding grounds near the tropics. There is also evidence of year-round residencies, and partial or age/sex-based migration. Blue whales are filter feeders; their diet consists almost exclusively of krill. They are generally solitary or ...
The sightings are separated by a 13,046 km great-circle distance - the minimum distance for the route the whale might have taken, the scientists say, though it is likely to be much greater.
