Candy for the birds
When my son was little, he had a collection of frogs in a tank in his bedroom (no less), and I had to go to the pet store a couple times a week to purchase these disgusting little black worms to feed them.
You'd put some of the squirming mass on the tip of your finger and the frogs would literally jump at your hand to eat them.
You can see why I am not a fan of mealworms, despite how much birds love them.
Mealworms are dessert for birds, and like kids, the birds like dessert best. But unlike cookies, cake and pie, mealworms are a vital part of a bird's summer diet as he beefs up for migration in the fall.
