Can you feed hummingbirds in feeder from maple sap?

Feeding hummingbirds with maple sap is not recommended. While it may contain some sugars, maple sap lacks the necessary nutrients that hummingbirds require, such as a proper balance of carbohydrates, vitamins, and minerals. Instead, it's best to use a sugar-water solution (1 part sugar to 4 parts water) in feeders, as this closely mimics the natural nectar they seek. Additionally, pure maple sap may ferment quickly, leading to potential health risks for the birds.
