The HummZinger Mini is a good choice if you wish to hang multiple hummingbird feeders so the less aggressive hummingbirds get a chance to feed in peace. Having just one hummingbird feeder may not be enough depending on your hummingbird population. Many times an aggressive hummingbird will chase away the other hummingbirds trying to feed. This feeder holds 8 oz., but the birds’ tongues can reach all the way to the bottom of the dish, so you can use less nectar if you wish. This easy-to-clean feeder is dishwasher safe. We love it, and it’s the only one we use at our house.
