Nectar Guard Tips
- For use with Jewel Box, HummZinger Ultra & HummZinger Fancy hummingbird feeders.
- 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 the beaks are removed.
- Nectar Guard tips create a barrier that flying insects can't penetrate.
