Nectar Guard® Tips easily slide onto the feeding ports on the underside of the feeder cover. The flexible membrane in the center of each tip easily opens when hummingbirds insert their beaks to feed and close up tight when beaks are removed. Nectar Guard tips create a barrier flying insects cannot penetrate. For use with the HummZinger HighView, HummZinger Ultra, HummZinger Fancy, HummZinger Little Fancy & Jewel Box Window Hummingbird Feeders. 12 tips per pack |
