How Rare is a Black Squirrel?
You might have heard of blue lobsters, but how rare are they? They have been found in Louisiana, and pink dolphins have surfaced several times. You may also have seen brown and white pandas in China. And, while the species is uncommon, there have been reports of black squirrel sightings in the UK and United States. Scientists believe they have a better understanding of why these creatures appear in certain places than others.
Although gray squirrels are relatively common, they are considered endangered in many parts of the world. Despite this, they are still very popular, especially for fur and food. Live traps baited with nuts and grains can be used to harvest the squirrels. Although gray squirrels are non-game wildlife, they are gaining in popularity due to the spread of cities and the destruction of their native habitats. Here are some interesting facts about these small rodents.
Despite their rarity, gray squirrels do not suffer from the low population density of other rodent species. Their home range is typically larger during summer months, when the population increases and there are fewer eastern gray squirrels to compete with. They live in two types of habitats: tree dens and nests. During breeding season, females nest alone while males share dens with other females. While males are docile, females are particularly aggressive during pregnancy, and males are often avoiding them.
Courtship between gray and red squirrels is similar. Males engage in mating chases with one to 10 females during estrus. One dominant male usually mates with the female, but not always. Gray squirrels have two breeding seasons, July-August and March-April. The females have litters one to two times a year, while yearling females bear one litter every year. The gestation period is about 40-44 days, and litters range in size from one to nine.
Melanistic morphs of gray squirrels
The melanistic morphs of gray squirrels are a relatively new phenotype and may be related to some of the species’ recent migration patterns. This study examined the frequency of melanistic morphs in squirrel populations. In the greater Wooster area, researchers conducted field surveys of 16 sites, which ranged in size from two to 22 square kilometers. Observations of squirrels in different colors were categorized according to whether they were urban or forested.
There are also black morphs of eastern gray squirrels that were introduced into some other regions of North America. Although they are not native to these regions, they can be found in pockets of urban areas, including the southeastern United States. Although black morphs are rare throughout their range, they can constitute up to 40 percent of the squirrel population in urban areas. Nevertheless, they are rare in most regions of the country, and may pose a threat to native gray squirrels.
Although melanism is rare in squirrels, it is a natural trait. This trait is advantageous in cold, damp climates. The red morph, on the other hand, lacks melanism and has two copies of the MC1R gene. The result is a pelt that is mostly black. But the gray morph has two copies of the complete gene, resulting in the melanistic morph of gray squirrels.
Chances of spotting a black squirrel
It is extremely rare to see a black squirrel in North America. One estimate puts its chances of occurrence at just one in every 10,000 squirrels. In fact, they are considered to be so rare that they have become an unofficial mascot of Kent State University. They are an interesting animal that people from southern regions of the U.S. often take in awe of. It may have been an accident that these animals were introduced to the United States from the South, but they’ve now adapted to living in the Midwest.
Although rare, there are instances where you might spot a black squirrel in the wild. Some moose are white in colour, and these moose are rarer than black squirrels. This means that your chances of seeing a white moose are far greater than your chances of finding a black squirrel. These animals are both considered vulnerable to humans and are therefore more likely to be spotted by wildlife enthusiasts.
The fur of a black squirrel is actually not that different from that of a gray squirrel. In fact, the color of a black squirrel may be the result of a genetic mutation that affects the fox’s genes. This mutation results in black fur, but it’s possible that many of these squirrels never reach adulthood. A black squirrel’s fur is also more durable, and this means it’s better adapted to colder conditions than its gray counterpart.
