  • Publication number: 20140322406
    Abstract: There is a need to protect the health of hummingbirds by preventing the rapid microbial spoiling of sugar nectar used in hummingbird feeders, without using artificial preservatives. The invention is a method, composition and kit, for naturally preventing spoilage of sugar nectar liquid food by using a transition metal salt, an optional acidifying agent, and an optional functional additive. Certain transition metal salts, such as copper sulfate are surprisingly effective in protecting sugar nectar even at micronutrient levels, below the level consumed by hummingbirds in their natural diet. The invention prevents the formation of unhealthy microbial growth, reduces the need for frequent changing, and keeps the sugar nectar fresh and healthy.
