Feed Hummingbirds out of your hand. Use with any nectar, great for children and seniors. Holds 0.3oz/10 milliliters of nectar, top-rack dishwasher safe. Place in a plant pot initially, once birds become acclimated to the feeder you can use it as a ring. By standing still and extending your arm it will invite these wonderful birds to land and take nectar. Cap lifts of base for easy cleaning. Made in the USA.
