But in what other ways are these bears different? And how can you learn how to tell them apart? In this article, we will go over all of these differences in detail so that you can learn the specifics about both Kodiak and grizzlies. Let’s get started and talk about them now.
Comparing Kodiak vs Grizzly
The Main Differences Between Kodiak vs Grizzly
There are many differences between Kodiak vs grizzly bears, particularly in the locations they are found. Kodiak bears are exclusively found in the Kodiak Archipelago in Alaska, while grizzly bears are found everywhere else in Alaska, along with other United States locations and Canada. Because of their special geographical location, Kodiak bears are larger than grizzlies after decades of living in isolation. Let’s discuss some of these differences in more detail.
Kodiak vs Grizzly: Location Found
The primary difference between a Kodiak vs grizzly bear is the location in which they are found. You will not find Kodiak bears anywhere else in the world besides the Kodiak Archipelago in Alaska, while grizzly bears are found in many other locations. Let’s talk more about these specific geographical locations now. Kodiak bears live in relative isolation and safety on the Kodiak Archipelago, and thus they have bred and essentially taken over this area. For example, a study shows that there is an estimated 1-2 bears per 0.6 square mile on the island, which is significantly more than you might think! These bears are completely separated from the standard grizzly, and therefore are considered their own subspecies. Grizzly bears are located in a few United States locations, like Alaska, parts of Wyoming, and other northern states like Montana, Idaho, and Washington. They are also located in parts of Canada, but the majority of grizzly bears are located in Alaska. This is how the Kodiak bears came to reside on the Kodiak Archipelago in the first place!
Kodiak vs Grizzly: Size and Weight
Another key difference between Kodiak bears and grizzly bears is their overall size and weight differences. While grizzly bears were thought to be the largest bear other than polar bears, Kodiak bears beat out grizzly bears in both size and weight. Let’s talk about this in more detail and why this might be. Given the relative isolation of the Kodiak Archipelago, Kodiak bears have the opportunity to spread out and grow larger. These bears are notoriously larger and heavier than grizzly bears, making them the second largest bear other than polar bears. The average Kodiak grows over 1500 pounds and stands anywhere from eight to 10 feet tall. The average grizzly tends to weigh up to 1200 pounds and only stands at 5 to 8 feet tall. While that’s nothing to scoff at, there is a huge difference when comparing the size and weight of a Kodiak vs grizzly. It is especially outstanding given that these two bears were once the same species, but Kodiaks have evolved to suit their surroundings.
Kodiak vs Grizzly: Diet and Behavior
When comparing a Kodiak vs grizzly bear, their diet and behavioral differences must be addressed. This is because Kodiak bears have evolved in two different social and dietary structures when compared to that of the grizzly bear, their former species classification. Let’s talk more about some of these differences in detail. Given the prevalence of food and lack of poaching or hunting, Kodiak bears eat far more than the average grizzly bear. They also have regular access to freshly caught salmon and other fish given their proximity and lack of competition. There are also vast amounts of edible vegetation for these bears to partake of in times when meat is not as abundant. Grizzly bears also seek salmon, as well as trout and bass from rivers, and they prey upon large mammals when they can find them, including caribou, elk, moose, big horn sheep, bison, and deer. As far as their plant diet goes, depending on the region they live in, grizzlies eat a wide variety of berries, tubers, whitebark pine nuts, and legumes. They will even go for smaller mammals and insects. If food is in abundance, grizzly bears can be known to feed in groups, but generally, competition for food is more fierce among grizzlies than Kodiaks. Because of their isolation, Kodiak bears have adapted. They formed complicated social structures that have not been observed in other bear species. This is because they understand that their resources should be shared amongst all Kodiak bears. Additionally, these bears simply have less to worry about than the average grizzly bear.
Kodiak vs Grizzly: Endangerment and Rarity
The final difference between Kodiak bears versus grizzly bears is their endangerment and rarity. Grizzly bears are located in specific locations, but they are more common than Kodiak bears overall. Kodiak bears are only found on the Kodiak Archipelago, and it is estimated that 3,500 Kodiak bears exist, total! This is a much smaller number when compared to the estimated 50,000 grizzly bears found throughout North America.
