Tag Archives: Whale Watching

Many of the humpback whales we observe in the waters of British Columbia have been identified with a number / name and have their pictures in a catalogue.  The underside of a whale’s tail shows a range of white patterns. These patterns added to any scars or other markings are unique to each whale.

One method of feeding we often see with humpback whales is “Lunge Feeding”. The whale will lunge through a shoal of prey with mouth gaping open often exploding at the surface with both food and water. In this case the photo shows the top of the humpback’s head with its lower jaw hanging open. Humpback whales do not feed in the warmer climates of Hawaii and Mexico where they spend the winter so it makes sense that once they arrive in their feeding grounds, this will occupy most of their time. Humpback whales in our area will feed small, shoaling fish such as herring. They may eat up to 1,400 kg (3,000 lbs.) of food a day.

While on a whale watching tour from Grizzly Bear Lodge we came upon a humpback whale tail lobbing or lobtailing. Lobtailing is the act of a whale lifting its fluke (tail) out of the water and then bringing it down onto the surface of the water hard and fast in order to make a loud slap. In this picture it is an upside down lobbing where the top of the tail is hitting the surface so the whale is on its back. If you compare photos this is the same humpback from the Oct 18th posting. In this case a guest counted 38 consecutive slaps that is a lot of energy expelled and no one is sure why.

Compared to the posting on October 1st this is the perfect photo to be used to identify a humpback whale. The underside of the fluke (tail) which shows the colour pattern, serrated edges and barnacles on the corners are unique to each whale. “Each individual humpback is given a unique alphanumeric identifier. Each identifier starts with BC to indicate that the animal was seen in British Columbian waters. Following the BC is an X, Y or Z, corresponding to the amount of white on the flukes and a number to identify the individual. BCX## contain approximately 0-20% white, BCY## have approximately 20-80% white and BCZ## have approximately 80-100% white. The catalogue is generally arranged in order of increasing white pigmentation. BCX flukes are further arranged into groups of similar appearance, and thus may not be in order of increasing white pigmentation.” Quote from the “Photographic Catalogue of Humpback Whales in British Columbia”.

s a guide when I take photos in the boat I try to put things in perspective. For convenience I use a small Pentax OPI waterproof camera. This photo shows a guest taking a picture of a humpback whale fluking in the background. With the camera he was using and the closeness of the whale he has a good photo to take home and show his friends. This brings me to a word of caution I give all the guests in my boat: “Put down the camera and enjoy the experience”.  If on your vacation, especially on wildlife tours, if you view everything through the lens of your camera you will miss more than half of the experience.

Whale watching trips from the lodge will often eat their picnic lunches on the water. Sitting quietly becomes a time for excellent viewing of the surrounding marine life. Humpback whales are very cautious is an area with boats traveling likely because they cannot be sure of their direction of travel or any sudden change that may occur. But we have found that by sitting quietly while other tour boats are returning to exchange their guests we are able to enjoy close up wildlife viewing.
