The Best-1 8 Ounce Hummingbird Feeder holds 8 ounces of nectar. This feeder is bee and wasp proof, features a built-in perch, and has 8 feeding stations. The red bottom is designed to prevent other birds and bees from drinking the nectar, due to the sunken cap. The 8 ounce glass bottle has a lot of eye appeal. This feeder is heavy when full thus eliminating the chance of nectar waste or swinging in the wind. The base separates from the bottle for easy cleaning. This feeder will not rust. Made in the USA.
