    I always wonder how can an animal get protein, minerals, and vitamins from such a restricted diet?

        They don’t eat plants. They suck nectar. My curiosity got the better of me.

        “Although a high-quality source of energy, nectar is deficient in many macro- and micronutrients it tends to be low in lipids, and although it may contain trace quantities of amino acids, some essential acids are severely or entirely lacking. Though hummingbird protein requirements appear to be quite small, at 1.5% of the diet, nectar is still an inadequate source most if not all hummingbirds therefore supplement their diet with the consumption of invertebrates.”
