Sapphire Labs Hummingbird Feeder Fresh Nectar Defender
Hummingbirds naturally consume micronutrient copper in their daily diet of insects and nectar. It is something they must have for their normal growth and development. • Nectar Defender is well within the natural range of copper found in wild hummingbirds diets. The arthropods that hummingbirds eat can be many times the copper level in Nectar Defender. And, the copper level of Nectar Defender combined with arthropods is substantially within a hummingbird’s natural range. • Micronutrient copper has shown to be safe for hummingbirds in long-term studies of hummingbirds’ diet conducted by University of California Avian Scientists, and at zoo and wildlife rehabilitation organizations to successfully maintain the long-term health of their hummingbird colonies for years at a time. • To ensure Nectar Defender is safe, the amount of micronutrient used in Nectar Defender is below the level tested in these long-term studies and below the level recommended by the Association of Avian Veterinarian
