The humpback whales that migrate to Hawaii seasonally have always been a source of interest among both visitors and residents. For those who keep an eye on that blue horizon, they can put on quite a show with their acrobatic antics. Their great size and charismatic behavior are just a couple of reasons why our Maui whale watch tours are so popular. Although there are still some mysteries remaining as to the lives they lead below the waves, scientists have discovered many fascinating things about our humpback neighbors.
Humpbacks are found throughout the world's oceans, although their numbers dipped dangerously low as a result of whaling in the 1800's. It's estimated that as few as 1,000 were left in 1965. Now, there are an estimated 6,000 North Pacific Humpbacks alone. One of the interesting things about the humpbacks is the somewhat distinct populations they form. For example. In the North Pacific, there are three populations. The eastern stock migrate between Northern California in summer and Mexico in winter. The western stock summers in the Aleutian Islands and moves on the islands south of Japan in winter. The central stock can be found here in Hawaii in the winter, after spending their summers in southeast Alaska and the Gulf of Alaska in summer. The whales aren't too strict about their migrations though, as some mixing on the breeding grounds has been observed in all of these groups, which probably goes a long way to keeping the gene pool nice and diverse.
Hawaii's waters provide such an important habitat for these whales that Congress designated the Hawaiian Islands Humpback Whale National Marine Sanctuary in 1992, where the whales would be protected as an endangered species by both federal and state law. Luckily for us, one of the two most popular places for whales to congregate is in the waters of Maui County, meaning the area between Maui, Lanai, Molokai and Kaho'olawe. Their other popular spot is to the southwest of Molokai. As their numbers continue to strengthen, they have made progress spreading out toward the other Hawaiian islands.
Our whales from Alaska leave their feeding grounds in the fall and swim almost non-stop until reaching their breeding grounds in Hawaii, which can take between 6-8 weeks. At about 3,000 miles each way, it's one of the longest mammal migrations, which is why it takes them so long despite their epic size.
Marine scientists have made some interesting discoveries about Hawaii's arriving whales. Namely, who arrives when. Nursing mothers arrive around mid to late November, generally being the first on the scene. The next to arrive are juveniles and newly weaned yearlings, followed by a surge of adult males, and then adult females. The last to arrive are pregnant females, who feed in Alaska as long as possible before beginning their migration.
