My guys love this:

Fresh Fruits (berries work best)
Nuts (optional)
Seed

Blend all ingredients until they form a smooth paste. Pour the mixture into popsicle molds or ice trays. Freeze the pops until they are solid. As an option, you can cover the trays with plastic wrap, and insert halved popsicle sticks through the wrap and into the pops before freezing, to give your bird something to hang on to.

what a great recipe. I'll give my guys a piece of a regular ice pop during the summer, now I'm going to have to try this.

You are a genius! Ruby is going to LOVE this! she loves ice cubes in an old sock, but I never thought of something healthy for her to eat. "STEP-UP!!! STEP-UP!!!!"

that is a good idea! i might have to try that on one of these super hot days
