An easy supply of food from bird tables and feeders encourages grey squirrels to multiply and spread. They can travel long distances and quickly become a threat to red squirrels by spreading disease or out-competing them for food. Using a squirrel-proof bird feeder will deter grey squirrels, but still allow your garden birds to feed.
We know that visitors staying in self-catering accommodation like to feed the birds. Making this small change to squirrel-proof feeders increases the chances of seeing red squirrels on holidays in future.
Reasonably-priced squirrel-proof feeders are available at local garden centres and online, for example on Amazon. The RSPB has further advice>> on deterring grey squirrels from your garden.
