Grizzly Bears
Read MoreThis is an overview of The McNeil River, Alaska where I took the Grizzly Bear photographs that you will see on the website. It was late August, and the bears were feasting and fattening up on the salmon that were returning to the same fresh water, from which they had hatched some 2-1/2 years earlier. They would soon go into hibernation where they fall asleep for several months. Bears are inseminated in the summer, but they have the ability to delay nidation until they find a den site and fall asleep. The impregnated females will bear, without awakening, 1-3 babies. During hibernation, the bear will not eat, defecate or urinate until they awaken the following March or early April! The one pound newborn infants, on their own initiative, will find and feed on the mother's teats, from which they will grow and prosper on her rich milk. When she does awaken, she and the cubs exit the den. She is much thinned down and " Hungry as a bear!" [The McNeil River, Alaska].
A closer view of the McNeil River with many bears fishing.The white objects are gulls, whose screeching is deafening. They are fighting over the remains of the salmon left by the bears. Smoke can be seen coming out of the active Augustine Island volcano in the distant background. [McNeil River, Alaska].
During the summer and early fall, Grizzly (Brown) Bears will eat as much as they can to store up fat to last them through the winter hibernation--and for the females, adequately to nurse their newborn babies, until they waken in early spring. They will have consumed no food or water during hibernation. The female actually becomes impregnated in late spring or early summer, but the nidation [implantation & development of the fertilized egg(s)] is delayed until early winter (late September-early November). Once they find a suitable den, they proceed to hibernate. The pregnant females will give birth to 2-3 cubs, without awakening or being aware of their birth. (I can hear our ladies saying:"I'll buy that!").The babies weigh about a pound, find the teats, and nurse entirely on their own initiative. [McNeil River, Alaska].
I watched these Sockeye Salmon shooting the rapids, striving so hard to get back up the rapids to reach the same fresh water pool in which they were spawned (after returning from 2 years at sea in salt water). I marveled at their determination, endurance, and skill. They first had to elude the seals and the fishermen in the ocean, and the bears and rapids in the river. I don't see how enough of them survived to perpetuate their species. [Chenik River, Alaska].
The grizzly is a superb fisherman who easily catches the airborne sockeye salmon shooting the rapids, or in the water swimming against the stream. They have no trouble compensating for the light refraction of water--even though to us it would cause the location of a fish to seem to be in a different position than it actually is. [McNeil River, Alaska].
The Grizzly uses its paw to brush the salmon onto the rocks and one foot to hold down the wriggling fish, as it tears off the skin with its teeth. The bear seeks the fatty layer just beneath the skin, and if it's a female fish, also the eggs. It knows that this is the high-caloric tissue that will best sustain her/him during the forthcoming hibernation. They became glutted and often left behind the much of the fish to be consumed by the gulls. [McNeil River, Alaska].
Grizzly, mother of 2 last-year's cubs, chases off a young male. He is probably her's from one of her former litters. The sow, with her 2 cubs of two springs ago, chases off the young male cub (3 years old), because she is protecting her current young cubs. At 2 years the cubs are chased off! The cub had previously been chased away and is too old to remain with his mother. She does not intend to hurt him, she just wants him to stay away.The following images show that she is serious about his leaving.[McNeil River, Alaska].
Shortly after a young cub reaches 2-3 years old, the mother Grizzly will drive it off. (It is thought that this practice is to prevent inbreeding). The young cub has returned to an area with which he was familiar, but moma now has two new cubs, and she won't tolerate his presence. One of the indications that this male is not a stranger, and nothing serious will happen, is that her present cubs are perfectly relaxed. [McNeil River, Alaska].
A different mother Grizzly and her 2 cubs, which are a year older than 'Spring Cubs', having been born 2 winters ago.The mother takes her cubs down to the river to get them accustomed to the water, and to the presence of other bears. Mothers are excellent teachers, and she will teach them to fish, as well as all the other things they need to know to survive when they are driven out. [McNeil River, Alaska].
Mother & Two Cubs Resting on the Beach

My guide & I were standing together on the rocks of the Chenik River, watching two young Grizzly Bears fishing, when suddenly one of them wheeled around and came towards us. The three images will show him climbing out onto the rocks, very close to where we were standing. Note the water pouring off his fur. [McNeil River, Alaska].
We were standing no more than 10 feet behind that small log that you can see in the foreground. We remained absolutely still & close together. Suddenly, my guide took a stance and pointed his rifle towards the advancing bear, and yelled "Stop". The bear paused, thought a moment, and then returned to the river. This is the closest call I have ever had with wild animals. I guess this young fellow was just curious. (I have become accustomed to being close to wild animals from many safari trips to Africa).
