With the Perky-Pet glass hummingbird feeder, entertaining hummingbirds in your backyard has never been easier. It is the classic design that you know and love with a few great updates, including a new and improved wide-mouth bottle and bird-preferred U-shaped perches. Meanwhile, the attention-catching colour and 8 oz nectar capacity are irresistible to hummers. The Perky-Pet hummingbird feeder also features convenient insect defenses. The bee guards keep bees at bay, while hummingbirds can still easily access the nectar. To keep ants away, fill the top of the lid with water to create a barrier that prevents them from crawling down to the ports.
