They found that there’s a natural darker-hue to some Fox Squirrels which has developed a theory that the mutation originated with them. Scientists have actually studied this melanism in squirrels by extracting DNA from both Fox and Gray Squirrels. This melonic variant (1) gene gives Black Squirrels they’re beautiful, unusual coloring. Per the Smithsonian Institute, it’s not uncommon to see these two species chasing each other around during mating season. However, it’s important to note that they’re really not a phenomenon at all but a rare DNA mutation of a Gray Squirrel that interbred with a Fox Squirrel. You can find them in Washington DC, Ohio, New York City and Ontario, Canada.Īfter introduction in the UK to a zoo around the earlier parts of the 1900s, they escaped and naturalized within the landscape. There’s also the phenomenon of Black Squirrels, often found across North America and England. However, this is usually the efforts of breeding in captivity rather than in the wild. For instance, Northern Flying Squirrels and Southern Flying Squirrels will interbreed on occasion. Therefore, hybrids are very rare among squirrels, but it does happen. In fact, squirrels are quite picky about their mates only selecting the best and brightest available. Even then, not all species within the breed mate together. The only other rodents that squirrels can breed with are other squirrels. While it’s true both these animals have roughly the same breeding times in early spring and late summer, there’s nothing about them that draws them to breed with one another. Squirrels love frolicking through the trees whereas chipmunks mostly stay nearer to the ground although they can climb up a tree from time to time. The tallest a chipmunk gets is 5½ inches whereas squirrels can get to a height of 12 inches. However, chipmunks are much smaller than squirrels. Chipmunk and Squirrel RelationĬhipmunks and squirrels barely notice each other as they go about their daily duties even though both are diurnal. That said, they technically may be able to interbreed, but no one has never seen it in nature and we have no proof of anyone attempting their husbandry. Much like rats, they’re physique, nature and habits are far too different to matchup. While it may seem as though Chipmunks should at least be able to mate with squirrels, they can’t. Whatever the reason, they’ve lost their fur and you’re seeing the real tail, not a rat-squirrel hybrid. What probably happened is either the squirrel, lost it’s tail fur in the nest (quite common), suffering from mange or malnourishment, or they got into a scuffle with another animal. If you look through the fur, you can see how his tail is actually quite long and thin, like a rat tail. Here is a picture I took of a squirrel hanging on my living room window screen. Squirrels have thin, fleshy tails much like rats but fill out completely in fur, which gives that bushy appearance. While there are some claims that people have seen squirrels with a rat’s tail, it could be true. This trait alone negates the possibility of them being able to mate successfully. They simply are incapable of responding to the mating call or creating each others’ call. squirrel’s mating call are completely different. More importantly, squirrels only mate in the springtime and late summer whereas rats mate all year round.Īdditionally, a rat’s mating call vs. They just aren’t around at the same times. With disparate daytime and nighttime activity, this makes interbreeding highly unlikely. Different Activity Makes Breeding Unlikely The only exception with squirrels is in the case of flying squirrels, which are nocturnal by nature. Squirrels are diurnal, or daytime active, whereas rats are nocturnal, or active at night. Most of this is due to how different they are in behavior, habit, mating patterns and overall physique. It is not possible for rats to mate with squirrels in any capacity. But this is more likely to be urban legend, since there is no way to verify these claims. If you do a search online for which other species squirrels can mate with, you’ll find some tall tales about people seeing them: either mating or producing offspring. They are different subspecies that cannot interbreed, it’s physically impossible. While they are all part of the same family, Squirrels and rats are not related. No, squirrels can only mate with other species in the squirrel family.
