Dried Calciworms – A Calcium-Rich Superfood for Wild Birds
Dried Calciworms, the larvae of the Black Soldier Fly (Hermetia illucens), are a powerful nutritional supplement for wild birds. Packed with approximately 50 times more calcium than standard dried mealworms, they are a perfect choice for supporting bird health all year round.
Why feed Calciworms to birds? Calcium is vital for a wide range of biological functions in birds, including:
-
Maintaining strong bones and skeletal structure
-
Healthy egg development in breeding females
-
Muscle contraction and nerve function
-
Efficient metabolism and immune support
Calciworms also help birds absorb phosphorus, another essential mineral, and are naturally high in protein and healthy fats, making them both nutritious and highly palatable to a variety of garden birds.
Ideal for year-round feeding, Calciworms are especially important during winter and spring, when natural food is scarce and birds need extra support during the nesting and breeding season.
Benefits of Feeding Dried Calciworms:
-
50x more calcium than standard worms or insects
-
High in protein and fat for energy and recovery
-
Supports egg production and bone health
-
Perfect for robins, blackbirds, tits, thrushes, and more
-
Recommended during winter and spring nesting periods
Add dried Calciworms to your garden feeding station to help keep local bird populations strong, healthy, and well-nourished throughout the year.
