Mealworms
Mealworms are a high calorie treat loved by birds of all shapes and sizes. Dried mealworms and calciworms provide a great source of protein during the breeding season and colder months. For best results, use a mealworm feeder or simply serve on a bird table. Try soaking mealworms in water to make them easier to digest or, for an extra energy boost, serve in bird suet.
