The All-Ireland Squirrel and Pine Marten Survey 2019 has been published by the National Parks and Wildlife Service. The findings are encouraging.

According to the Portugal Resident publication, red squirrels in  Portugal are being killed by a strain of adenovirus found in South Korea. Scientists are trying to establish how this has occurred.

The latest survey of red and grey squirrels in Scotland indicates that numbers are stable with some minor regional changes and some optimism for the future. Further details can be found in: The National, The Canary, The Herald.

Joshua Twining and colleagues from Queen’s University Belfast have recently published a study in Royal Society Open Science that shows that red squirrels are better than grey squirrels at detecting the scent of pine martens. This may be one reason why alien grey squirrels tend to ‘disappear’ when pine martens move into an area, whereas […]

Lisa Leaver and colleagues at Exeter University have studied whether grey squirrels are left-handed or right-handed in laboratory tests. Many squirrels appeared to favour their left or their right paw, but these squirrels performed less well than those which were ambidextrous. The studies, which will be published in the scientific journal Learning and Behaviour, contribute […]

The Roslin Institute in Edinburgh is spearheading a study to edit the genes of male squirrels to contain a gene-drive that, once the males are released, should quickly spread throughout the population and make future females sterile. The idea is that the spread of female infertility in the population will mean the population is unable […]

An unconfirmed case of a red squirrel with squirrelpox virus disease at Smardale Nature Reserve, Cumbria was reported by a Cumbria Wildlife Trust volunteer. The virus is carried by grey squirrels and the disease it causes in red squirrels is invariably fatal. Local people and volunteer groups are being asked to be vigilant and sterilise […]
