Here's something else you can do for hummingbirds. Though they get the bulk of their energy needs from sipping nectar or sugar water, they need more than that to stay aloft. Most of their protein requirements, for example, are met by eating small insects.
Banana skins seem to be especially effective.
By putting banana skins in an easily accessible spot on my compost pile, I've managed to lure Hackberry Emperors, Tawny Emperors, Empress Leilias, Red Admirals, and Question Marks. That way you'll recharge the fruit, maintaining its attractiveness to both butterflies and other insects. Banner Golden-cheeked Warbler photo copyright 1988 Greg Lasley. All rights reserved.
