How Does the Grey Squirrel Protect Itself Against Martens?how-does-the-grey-squirrel-protect-itself

So, how does the grey squirrel protect itself against martens? The answer may surprise you. Rather than fight or flee, these sociable rodents communicate with each other. Read on to find out! The Eastern Grey Squirrel spends most of its life in trees. It moves head first while climbing tree trunks, and it slinks around when danger approaches. It can also run up to 25 km per hour.

Grey squirrels have no defences against martens

The lack of defensive mechanisms in grey squirrels makes them easy prey for pine martens. In addition to being bigger and containing more energy, martens also tend to live in greater numbers. This is one reason why pine martens are causing the decline of grey squirrel populations in Britain and Ireland. A study by Joshua Twining of the University of Western Australia found that martens are killing more grey squirrels than they are taking in. The researchers studied marten scavengers and their diets to find out which species were preying on which.

They flee rather than fight

It may be surprising to learn that grey squirrels do not have as much natural resistance as once believed. A recent study by Dr Lisa Signorile, a geneticist at the Zoological Society of London and Imperial College London, analyzed the DNA of nearly 1,500 grey squirrels in the UK and Italy. Interestingly, the different populations are still genetically distinct, which makes it possible to trace the origins of a new species.

They communicate with each other

Many people are unaware that grey squirrels are a social species. While they have the ability to communicate with each other, they also use body language. Some species communicate with one another to protect themselves. In Ireland, grey squirrels have been decimated by pine martens, which have become a major threat to their population. The martens have also become a popular food source in some parts of Ireland.

They are sociable

The aversion to humans has helped grey squirrels adapt to their surroundings. While males are naturally shy and protective of their nests, females are sociable and firmly guard their territory. Males tend to expand their home range after weaning. Once established, individuals have a small number of recognized neighbours, promoting individual recognition and lowering aggressive levels among neighbours. The same applies to new animals, however, as new neighbors can cause problems for newly established individuals.

They are crepuscular

Like red squirrels, grays are crepuscular. During mating, 1-10 males will engage in a race to mate with a female in estrus. Females typically mate with the dominant male, but this does not always happen. Females in the eastern United States bear two litters a year – one in midwinter and one in late summer. Mating takes place in a leafy nest that is surrounded by leaves.

They are agile climbers and jumpers

Squirrels are excellent climbers and jumpers. They use tools to reach higher areas and will scamper along roofs and tear open tiny cracks to access higher places. Greys can jump over four feet and can leap more than ten feet vertically. While humans cannot leap so high, greys can easily reach a height of two meters. Whether the squirrels jump vertically or horizontally, they are an impressive sight to behold.

They bury their food

Squirrels have a remarkable sense of smell and can find hidden nuts by scent alone. This intelligence extends to the placement of food caches. Researchers have noticed that Eastern gray squirrels use deceptive caching, burying an acorn, covering the hole, and running off to a secret-stash location. Their technique is not a new one. But it does have an intriguing and unique twist.
