Humpback Whale Ventures Down Sound

A humpback whale that has spent the past two weeks lingering near Point Defiance and south Vashon Island appears to be a young adult in no visible sign of distress, Cascadia Research researcher Erin Falcone said Wednesday.
Falcone, who spent part of Tuesday in Dalco Passage photographing the whale, said it appears to be in good skin and body condition. The marine mammal research organization was unable to identify the whale because it didn't show its fluke, or tail, which contains markings unique to each individual animal.
Cascadia, an Olympia-based nonprofit organization, has thousands of humpback fluke photos on file from a just-completed three-year study of the North Pacific whale population. The multinational study involving about 400 researchers revealed a humpback whale population of 18,000 to 20,000 individuals, compared with 1,500 in the North Pacific when whale hunting was banned in 1966.
As the population recovers, humpback whale sightings in Puget Sound have increased to about one a year, Cascadia founder John Calambokidis said. Occasionally, a humpback ventures into South Sound, including a juvenile humpback spotted north of Johnson Point in July 2006 and another young humpback seen in Budd Inlet and Dana Passage in September 2004.
Based on dorsal fin images, which are not as conclusive as flukes, the Point Defiance humpback appears to be new to the area.
It was first sighted near Port Madison on Bainbridge Island on April 12, then settled into Dalco Passage between Tacoma and Vashon Island on May 12, said Howard Garrett of the Orca Network.
The whale was seen diving and surfacing repeatedly Wednesday.
The humpback, one of the largest whale species and known for its complex songs, was common in Puget Sound in the 1800s, before commercial whale hunting, Calambokidis said.
Local populations were all but wiped out by whaling by the turn of the century, he added.
This time of year, 300 to 500 humpback whales congregate to feed off the northern Washington coast west of Cape Flattery, he said.
Naturalist Notes:
This sounds like it's the little one we saw yesterday. This article was published on the Orca Network http://www.orcanetwork.org/. We were curious about this particular animal's behavior and called our marine mammal research friends, Adam U and Jean Olsen, as soon as we confirmed it to be a humpback. They got a wonderful shot of the animal's fluke yesterday, which they sent in to the Orca Network and Erin Falcone for indentification. Hopefully by figuring out who this guy is, we can piece together more of its story. It is our goal that by being active in the whale watch industry, we may see things that can help biologists develop a better understanding of cetaceans and how to help them. I'll be sure to let you all know when we get an ID on our humpback. We have a trip going out this afternoon at 1pm, and if we're lucky we might see this animal again.
