Each feeder comes with two one-ounce, dishwasher-safe, plastic feeding jars with lids.

1-3 hummingbirds will empty a jar of food in about 2 days (depending on the time of year, other available food sources, whether one bird is capable of defending the feeder from other birds, etc). However, the feeders are most effective against bees and wasps if changed daily.

Instructions for use included.

Size approximately 3” deep x 7” wide x 10” tall
