ACCOMADATES MULTIPLE BIRDS: Every feeder features four flower-shaped feeding ports with comfortable U-shaped perches that allow several hummingbirds to feed simultaneously, making these hummingbird feeders for outdoors ideal for busy bird watching seasons 8 OZ CAPACITY: Each 2-pack of glass hummingbird feeders have 8oz nectar capacity, providing ample feeding space for multiple hummingbirds while maintaining the perfect size for smaller yards and patios BUILT-IN ANT MOAT & BEE GUARDS: Add water to the built-in ant moat to keep ants away, while the bee guards prevent bees from consuming the sweet nectar inside the glass feeders. Creating this dual defense system allows each bird uninterrupted access so they can feed peacefully EASY FILL & CLEAN: Filling is simple as the wide-mouth glass bottle design makes it easy to add nectar while preventing spills. Cleaning takes little time, as the ant moat, base, and bee guard components are made to disassemble from the feeder so every part can be cleaned thoroughly BIRDWATCH WITH EASE: Watch the birds clearly as the glass construction provides high visibility from all angles, while the pinch waist-design creates an attractive and functional feeder that will last you through every bird season
