As the UK enters the critical breeding season, bird enthusiasts are being urged to look past expensive specialty seeds and toward their own refrigerators. With natural food sources still lean in early March, the RSPCA has highlighted a surprising hero for your garden visitors: Mild Cheddar Cheese.
While many “human” foods are dangerous for wildlife, mild grated cheese has become a secret weapon for supporting the high-energy demands of nesting birds.
- 🧀 High Energy: Cheese is packed with essential fats and proteins that help birds maintain their body temperature during chilly spring nights.
- 🐣 Nesting Support: The calcium in cheese is vital for eggshell formation and the bone development of growing chicks.
- 🪶 Soft Texture: Unlike hard seeds, crumbled cheese is easy for smaller birds and fledglings to digest.
- 🚫 Mild Only: It is crucial to use only mild cheddar. Avoid “blue” cheeses, highly salted varieties, or soft cheeses, which can be toxic or stick to feathers.
Fun Fact: While most birds are lactose intolerant, many species can process the low levels of lactose found in fermented dairy like hard cheddar. It’s why you’ll often see Robins and Blue Tits swooping in the moment they spot a yellow crumble on the table!
Why Spring is the “Hungry Gap”
March in the UK is often referred to by conservationists as the “Hungry Gap.” Last year’s berries and seeds have been depleted, but the new season’s insects and grubs haven’t yet emerged in large numbers. Providing a high-fat supplement like cheese can literally be a lifesaver for a bird defending its territory or building a nest.
The RSPCA “Kitchen Safe” Checklist
If you want to supplement your bird table this weekend, follow these safety guidelines to ensure your garden remains a sanctuary:
- Grate it Small: Never leave large chunks. Grate or crumble the cheese so it’s easy for small beaks to carry and swallow.
- Mix it Up: For a “superfood” mix, combine grated cheese with soaked sultanas or unsalted bacon bits (fat only).
- Cleanliness is Key: Uneaten cheese can spoil quickly in the sun. Only put out what will be eaten in a few hours and clean your bird table regularly to prevent the spread of diseases like Trichomonosis.
FAQ Section
Is bread a good alternative? No. While birds will eat it, bread is “empty calories”—it fills their stomachs without providing the necessary nutrients for breeding. Cheese is a much denser, more effective energy source.
Can I give them leftover pizza cheese? Avoid any cheese that has been cooked with oils, spices, or onions, as these can be fatal to birds. Stick to plain, uncooked mild cheddar.
Which birds will visit for cheese? You can expect to see Robins, Blue Tits, Great Tits, and even Blackbirds showing a particular interest in your cheesy offerings.
