Vertebrates like birds can be used as pollinators in botanical garden conservatories as alternatives to insects to provide the same ecological functions. Some suitable bird species mentioned include tanagers, red-legged honeycreepers, violaceous euphonias, bananaquits, white-eyes, and roul roul partridges. Guidelines are provided for acquiring birds from reputable sources, quarantining them, and maintaining a healthy exhibit. While annual food costs for the birds are estimated to be $3,000, the immeasurable guest experience is considered priceless.
