In most species of squirrel, the female alone looks after the young, which are weaned at six to ten weeks and become sexually mature by the end of their first year. In their 2003 paper to the journal Biological Conservation, the biologists concluded: This conclusion is in broad agreement with other studies indicating that food availability (conifer seed) is the main factor limiting numbers of tree squirrels, not predation.. These stores help them survive winter food shortages. Squirrels, being primarily herbivores, eat a wide variety of plants, as well as nuts, seeds, conifer cones, fruits, fungi, and green vegetation.

Size: 8-10cm with a very long tail of up to 10cm. McRobie and her colleagues have also found that this genetic difference is incompletely dominant meaning squirrels can be either grey, black or black-brown, according to whether the squirrel has two normal-length MC1Rs, two short receptors or one normal and one short receptor. Whereas the grey squirrels were introduced into the UK from . Now red squirrels are confined to Scotland, pockets of northern England and Wales and small islands off England's south coast. A study of North American fox squirrels (Sciurus niger), which are close relatives of our grey squirrels, suggests that larger tail flags could also indicate frustration. In comparison to mice, voles have much shorter and more rounded snouts. Monitoring changes in the population is an important part of this and conservationists have seen some success with moving some red squirrels from stable populations into specially chosen areas that the species used to be found in., Outside of the UK, red squirrels are common across continental Europe and Asia. Red squirrels are the UK's native species and have lived here for around 10,000 years. Some biologists suggest any apparent relationship may simply reflect the Red squirrels ability to venture onto thinner branches than Greys and therefore evade martens more effectively.

Deceptive caching may serve as a distraction, preventing carefully foraged food from being stolen immediately by other opportunistic squirrels., When winter's fresh food shortages arrive, squirrels will locate and use up most of their stored supplies, but they won't find them all again.
