Humpback Pectoral Fin

Humpback whales are common in the waters between Vancouver Island and the BC mainland. A normal viewing day from the lodge will encounter more than a dozen whales which often put on dramatic displays of breaching, lobtailing and fluking. In the case of this photo slapping a pectoral fin like a tail.  Comparing it to yesterday’s post one can see way from a distance it could be mistaken for an orca. An interesting fact is that the humpback whale’s large pectoral fins have been the inspiration for the development of new aerodynamic technology to help fast-moving helicopters, maintain lift and increase maneuverability. The bumps on the pectoral fins of humpbacks have been used as inspiration before, in the development of turbine blades used in wind turbines, hydroelectric turbines and ventilation fans that increase efficiency.

Killer Whale Dorsal Fin

Orca, killer whales or blackfish are all the same and the residents return by late June most years. Our whale watching safaris are in the area of Johnstone Strait between Vancouver Island and the British Columbia mainland. This photo of a male orca shows a mature dorsal fin.  Following are some interesting fact about dorsal fins taken from www.seaworld.org/infobooks/killerwhale.
1.  Like the flukes, the dorsal fin is made of dense, fibrous connective tissue, with no bones.
2.  The dorsal fin acts as a keel.  The dorsal fin probably helps stabilize a killer whale as it swims at high speeds but is not essential to a whale’s stability.
3.  The dorsal fins of male killer whales are the tallest of any cetacean in the world, growing up to 1.8 m (6 ft.).  Female dorsal fins are smaller at about 0.9 to 1.2 m (3-4 ft.) and may be slightly curved back.
4.  For male killer whales, dorsal fin growth is thought to be a secondary sexual characteristic as peak growth of the fin coincides approximately with the onset of sexual maturity.
5.  Because of the huge diversity of killer whale dorsal fins and the adjacent saddle patch, researchers take pictures of these fins to identify individuals and their pods, much like fingerprints are taken to identify humans.

Grizzly Bears September River Trip – 4

The bears move into the water and down river still looking for salmon. This mother and cubs are quite fat for this time of the season so their daily routine of walking the river in search of food must be a successful.  Not that these pictures were taken with a point and shoot Pentax Opti 6mp 3X Optical Zoom I can only imagine the quality of the photos my guests obtained with their long lens camera and then again maybe we were to close.

The mother grizzly and cubs have climbed over the log and are about to enter the river just behind the boat. If you look over the previous photos in this series of postings you will notice the grizzly did not make eye contact by looking toward the boats – staring a bear in the eyes is a sign of aggression. And the guests were cautioned that it was ok to glance and take pictures but to avoid “bug eyed staring”. The mother had her head down while the cubs would occasionally glance toward the boats when a camera was making noise. …. more tomorrow

You my notice that both the guests head and the bear are in reasonable focus so the distance is close. At this point the mother grizzly bear was about fifteen meters or less than fifty feet across the river from the boat. Knowing the bears and their habits we were very safe in our location. These same bears had being coming down the river for about five days and had accepted the boats presence and as you may have noticed there was a larger boat ahead of ours and another behind, enough to make the bears very cautious…. more tomorrow

A beautiful fall morning on the Glendale River located on Knight Inlet, which is part of British Columbia’s Great Bear Rainforest. We had left Grizzly Bear Lodge at 7:30 for the hour and half boat ride up the inlet to the river. After taking Angus’s guest to shore for the SUV ride up to the viewing stands my guests climbed into the flat bottom river skiff for an estuary tour. If you check the Jan 1st posting “Google Map of Spawning Channel” it shows the yellow dot of the float and we went from there into the river and up past the tree line. At times pulling the boat over the sand bars and up the shallow river but as the tide came in we were about half a mile into the tree’s when we saw this mother and cubs coming down river. We had moved to the riverbank and I was standing in hip deep water holding the boat…… more tomorrow

 

Grizzly cubs – different size and colour

grizzly cubs size matters
Click to enlarge then click again

This photo shows that grizzly bear cubs are often different colours and can be quite different in size even though they are siblings. The size difference is often a result of one being a male and more aggressive than a female. This means first to nurse and the first to solid food once they are on the beach in the spring. It could also be due to the fact that siblings may have different fathers as females will mate with multiple males. A genetically larger male may produce a larger cub.  And the difference in colour is a result of the different mating partners. As the season progress and salmon become more of their diet the oils will cause the fur to darken but these are “spring cubs” and salmon are not in the rivers.

Grizzly Bear Lodge in the morning

A quiet morning departure from Grizzly Bear Lodge located on Minstrel Island (Knight Inlet) at the edge of BC’s Great Bear Rainforest. Depending on the season tours leave either by 7:30 or 8:00 and return between 3:00 and 5:00 depending on the days success. Guests often want a picture of the lodge and dock as we leave or return in the afternoon. Accommodating eight to ten guests allows for the personal touch from the gourmet meals to sharing the boat with a maximum of five people including the guide. The limit placed on the number of guests in camp is often one of the main reasons guest first select Grizzly Bear Lodge but by the time they leave it is the family atmosphere and the years of experience of all the staff that makes the visit memorable.

tel slapping whale

This photo taken an hour earlier than yesterday’s post shows a humpback whale fluking or lobtailing. Lobtailing is the act of a whale lifting its fluke 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. Large whales tend to lobtail by positioning themselves vertically downwards into the water and then slapping the surface by bending the tail stock.  They are likely to slap several times in a single session. The sound of a lobtail can be heard underwater several hundred metres from the site of a slap. This has led to speculation amongst scientists that lobtailing is, like breaching, a form of non-vocal communication. Also some suggest that lobtailing in humpback whales is a means of foraging. The hypothesis is that the loud noise causes herring to become frightened, thus tightening their school together, making it easier for the humpback to feed on them.

Whale watching safaris from the lodge this summer saw allot of activity from the humpback whales. Most days there were more than a dozen whales in the area of Bold Head on Blackfish Sound which is adjacent to Johnstone Strait and Vancouver Island on BC’s coast. There were two families of mother and calf in the area and the calves were very active. In this photo the calf was quite close and spent time throwing it’s back half of its body sideways out of the water. It would come up with it’s upper body part way out of the water and then throw it’s back half up and to the side.  This was a repeat performance going on for the better part of five minutes with a rest and then trying again.  From my searching scientists aren’t sure if this breaching behaviour serves some purpose, such as cleaning pests from the whale’s skin, or whether whales simply do it for fun.
