Strategies for Protecting Your Garden Bird Feeders from Squirrels

Selecting the Ideal Feeder

• Opt for Squirrel-Proof Designs: Invest in feeders specifically designed to deter squirrels. The most effective models feature a protective cage that permits small birds to access the food while excluding squirrels and larger birds. These caged feeders are available for various types of bird food, including seeds, peanuts, and fat balls.
• Weight-Sensitive Solutions: Some feeders come equipped with mechanisms that close feeding ports or retract the feeder when a squirrel's weight is detected.
• Choose Durable Materials: Squirrels can easily gnaw through plastic, so it's essential to use feeders made of robust metal. Even wire mesh may not be safe from their strong teeth.
• Avoid Rope or String: Hanging feeders with rope or string is an invitation for squirrels to chew through and access the food.

Fortifying Your Feeders

• Strategic Placement: Keep feeders at least 10 feet away from any surfaces that squirrels can leap from, such as tree branches, fences, or walls. Squirrels are capable of jumping impressive distances.
• Use Baffles: Install a dome or disk above the feeder to prevent squirrels from descending onto it. Similarly, a downward-facing cone or biscuit tin on a pole-mounted feeder can act as a barrier.
• Grease the Pole: A slippery pole can thwart a squirrel's climbing efforts. However, use grease sparingly to avoid harming the animals' fur and feathers.
• Hosepipe Trick: For feeders suspended on a line, threading the line through a hosepipe can create a spinning obstacle that squirrels will struggle to overcome.

Deterrents and Distractions

• Spice It Up: Birds are unaffected by capsaicin, the compound that makes chili peppers hot, but squirrels detest it. Mixing a tablespoon of cayenne pepper or chili powder into 5 kg of birdseed can discourage squirrels from eating it.
• Feed the Squirrels Separately: As a last resort, providing squirrels with their own food source away from the bird feeders might keep them occupied. While it may be costly, considering a squirrel can consume about half a kilo of food per week, it allows you to enjoy observing these intelligent creatures without them disrupting your bird feeders.

Interesting Statistics and Facts

While the strategies above can help deter squirrels, it's fascinating to note that according to a study by the University of Exeter, grey squirrels can remember problem-solving techniques for up to two years, which means they can potentially recall how to overcome obstacles to reach food. This highlights the importance of consistently applying and varying deterrent methods.

Furthermore, the Wildlife Trusts report that grey squirrels are one of the major reasons for the decline in native red squirrel populations in the UK, as they compete for food and habitat. This adds another layer of complexity to the issue of feeding garden birds while managing squirrel populations responsibly.
