In Council Bluffs Iowa they have 3 kinds. Black Grey and red. In Minnesota they have flying squirrels. It is just where they have been introduced into those areas and have thrived. Squirrels can't buy airline or bus tickets to travel so they are where they are unless humans intervene and move them which they do from time to time. That's how the black squirrel got to Iowa.Why do squirrels in different places have differing coloring ?? Ex. USA EAST - GREY, Canada - black?
Because there are different species all over North America, end their areas overlap given you the sense they are just a single species. There are local color patterns in different areas, and changes due to evolutive reasons, giving some individuals advantages over neighbors with a color not so well suited.Why do squirrels in different places have differing coloring ?? Ex. USA EAST - GREY, Canada - black?
There are different species of squirrels. The ones where I live are gray and there are some that are brown.
I grew up in southern ontario and the Eastern grey squirrel (Sciurus carolinensis) has two color phases there, grey and black (same species, just different coat colors). It has a wide distribution in the east of NA.

The eastern fox squirrel (Sciurus niger) also has a broad distribution in the east.

It is more brown in color, and at least where I am in Texas is smaller than the grey squirrels in Ontario, but that may just be a latitude difference. I have not seen grey squirrels here, apparently they are more common in east Texas.
In terms of why there is the color polymorphism in the eastern grey squirrel, I have never seen a study that tried to explain it, though I haven't looked carefully (try google scholar). I don't think it causes nonrandom mating (grey with grey, etc) but I may be wrong about that. There may be a selective difference that varies over geographical area.
Evolution! I am not positive that the squirrels in different areas of the country are actually different species, as many species of animals like the ';grey'; squirrel have been misnamed before. Humans have many different hair colors, but we are all the same species. However, you see certain combinations in certain environments as a result of natural selection. Very fair-skinned people in Africa or the Middle East would be susceptible to sunburns and skin cancer, and might even be easier to spot against dark sand and dirt. Therefore, you see fair-skinned Scandinavians, dark-skinned Middle Easterners, and almost black-skinned Africans. The very homogenous look that Asians have is largely due to geographic isolation (ie Japan).
Evolution drives variation different ways. For example, in the eastern US any squirrels that are black might be immediately more noticeable to predators and the black coloration is therefore evolutionarily less favorable. Perhaps the same is true for grey squirrels in Canada. Or, to make things even more compliated, maybe there's genes linked to coat color. Even if grey squirrels are EASIER for predators to spot than black squirrels, they may still dominate an area. Maybe certain immunities are associated with being grey. Let's say grey squirrels are resistant to parasite or disease X, and disease X is present in the eastern US. Grey squirrels will therefore be infected less and could have more grey offspring than black squirrels have black offspring (disease often lowers reproductive output). However, in Canada, this disease may not be present, so the advantages conferred by not being seen by predators outweighs the lack of immunity.
Evolution and genetics is an endlessly fascinating (and complex) subject. To me at least! :)
Many things can influence different coloring in types of squirrels, such as geographic isolation, or the environment in witch they live in. Coloration may also assist in attracting a mate??? I'm no expert, but I know a little bit about them.
Probably has something to do with the color of their surrounding environment. They would evolve different fur colors to blend in.

Squirrels which one is native to north America black or grey and what about colour perception.?
There are many squirrels native to North America. It depends upon where you live. The eastern grey squirrel can be black as can the red squirrel. Never saw a black fox squirrel though. I did see some black Abert's squirrels that looked as big as a cat to me.

http://www.squirrels.org/names.htmlSquirrels which one is native to north America black or grey and what about colour perception.?
Squirrels have various color phases, some populations have a dominance of one color phase, but they are all the same species. The common name is eastern gray squirrel, the scientific name is Sciurus carolinensis, many people drop the eastern part of the common name. They have been native to North America for 37 million years.

I don't understand what you mean by color perception. You mean the color phases or the animals vision.Squirrels which one is native to north America black or grey and what about colour perception.?
They do perceive color.makeup skin

In a hypothetical population of squirrels, the dominant fur color is black. A recessive allele for....?
grey fur color occurs with a frequency of 0.3. what is the frequency of the domiant allele?
a. 0.09
b. 0.42
c. 0.49
d. 0.70In a hypothetical population of squirrels, the dominant fur color is black. A recessive allele for....?
q = 0.3
q + p = 1.0. So p,frequency of dominant allele is 0.7.

Can black or grey wild squirrels mate and produce offspring with hampsters? maybe cavies??
are the genetics the same ? i saw a cat and a rabbit have a (cabbit).....there was a picture in our newspaper of a cat that gave birth to 3 kittens and 3 puppys! ';boweowwwCan black or grey wild squirrels mate and produce offspring with hampsters? maybe cavies??
zebras and horses are closely related. female Llamas and males camels can breed (not the other way around though) and produce a hybrid. A cat and a rabbit and a cat and a dog can mate, but can not have viable offspring. You may be thinking of the breed of cat that has extra short front legs- which makes them hop like a rabbit- I think the breed started in Canada. It is basically an outcropping from making the munchkin breed
Black and gray squirrels are the same species- black is a melanistic phase and dominant over grey- but (to put it simply)grey squirrels don't see the black or blonde squirrels as attractive, so it keeps the black or blonde population of gray squirrels down.
For one thing- cavies are not found where grey squirrels are found (they are in mostly S. America) and the genetics are way too different to be able to breed them to a hamster or cavie.Can black or grey wild squirrels mate and produce offspring with hampsters? maybe cavies??
All of these animals have different genetic makeups and number of chromosomes...they are not the same species and would never produce viable offspring. That cabbit has to be a freak of nature due to a birth defect and someone played it up in the news....you've seen old carnivals with malformed people put up for viewing as sideshow freaks...this cabbit must be the same or else a great computer fused photo!!! Sorry.....
No, genetics not only say squirel/hamster hybrids would be impossible, so are cabbits and a cat having puppies. Flat out, right down to it, species don't mix, and subspecies don't mix well.
Rabbits are not feline, so that makes that impossible. Cats are not canine, also impossible. Squirels and hamsters are both rodents, but in the sense as an african lion is in the same category as the house cat I have sleeping on my bed right now. Not only would the squirel kill the hamster, but any mating that took place would bear no fruit. Sorry, your paper runs lies. Are you sure you aren't looking at a tabloid?
no they can't, they are two different species. the cat %26amp; rabbit must have been concieved in a petrie dish.
Yaaaaaaahahahahahahahahaaha

With female grey squirrels preferring black mates - I joke not - are they copying female human behaviour?

The little sluts. Must be something in the drinking water. Got to be that.With female grey squirrels preferring black mates - I joke not - are they copying female human behaviour?
If the Grey Squirrel is mating with black squirrels oh well but in regards to white women being with black men, they are just whores and will eventually be wiped out, hopefully by one of my many weapons.
I think even squirrels can appreciate more aggressive sexual behavior! It is not the colour that is attracting them, it is the higher testosterone levels!
good glad the new black squirrels are taking over the grey, just like the american grey coming over and taking over our red sqirrels, fuc*ing americans
awww there so cute =0)
Please dont include me in that 'female behaviour'
Never eeeewwwwww x
I DONT KNOW. MAYBE YOU ARE FUNNY NOT RACSCIST
PMSL! I'd answer that, but i'd probably be shot....

I rent a house surrounded by black walnut trees, and the house is infested with squirrels, Im going insane!?
I have had critter control out and they said my house ';makes them want to get a new career';, I've tried fox urine it doesnt work, Im going crazy with the noise, has anyone had this bad an infestation? because i cant get rid of their food source (the black walnuts)!!!I rent a house surrounded by black walnut trees, and the house is infested with squirrels, Im going insane!?
Get a cat. Our cat loves squirrels. She chases them right up the tree.I rent a house surrounded by black walnut trees, and the house is infested with squirrels, Im going insane!?
Try a dog. My dog loves to chase squirrels and he never hurts them, but he keeps them out of my garden.

Squirrel cage blower (old,from home heating system) has 4 wires, red, orange, brn, black. how to wire for use?
The color code is a little bit odd.
Sounds like a multispeed motor.
Black is usually high speed, red is usually low speed.
Normally a white would be neutral, but you don't mention white.
Orange and brown may be wires for a capacitor.
The best thing to do is look at the motor nameplate, it may be covered by the belly band mounting but should show the correct way to wire and what capacitor to use if it uses one.Squirrel cage blower (old,from home heating system) has 4 wires, red, orange, brn, black. how to wire for use?
take ohm readings between the wires.the windings are most likely wound in parallel. one set will run it on high (most likely red and black)
the orange and brown are to add another pole on the motor halving the speed and doubling the toque.
