The Eurasian red squirrel (Sciurus vulgaris) is our only native species of squirrel, but it is under threat, having nearly completely disappeared from most of the UK in just under 150 years: declining from around 3.5 million to just 140,000.In 2020 the Mammal Society released an official Red List for British Mammals, highlighting the species most at risk. One study showed that females that survive to at least one year of age have an average life expectancy of 2.3 years. Daily Life: red squirrels are diurnal and are active for much of the day, often from before dawn until it is dark, pausing only for a midday rest.

The American red squirrel is amongst the smaller of the tree squirrels. Squirrels make a rough nest, called a ‘drey’, of twigs, leaves and strips of bark in the fork of a branch, high in the tree canopy.
