When it comes to choosing a hummingbird feeder, one of the most important factors is finding one that will not rust. Rust can contaminate the nectar, potentially harming hummingbirds. It also leads to leaks that waste nectar. There are a few key things to look for when selecting a rust-resistant hummingbird feeder.
Plastic Feeders
Plastic feeders are a great option for avoiding rust. High quality, food-grade plastics like polycarbonate are impervious to water and will not corrode. Make sure to look for plastics marketed as UV stabilized. UV light can cause plastics to become brittle and degrade over time. A UV stabilized plastic feeder will maintain its integrity for many seasons.
Stainless Steel Feeders
Stainless steel is another excellent choice for a rust-free hummingbird feeder. Stainless steel contains chromium, which forms an oxidized layer on the surface of the steel. This oxidized layer prevents rust from forming. High quality stainless steel with at least 18% chromium is ideal for a feeder.
Things to Look for in a Stainless Steel Feeder:
- At least 18/8 grade stainless steel (18% chromium, 8% nickel)
- Brushed finish (not polished) for maximum rust resistance
- No seams or crevices where water can collect
- Leak-proof sealing around hanging wires, openings, and feeding ports
Glass Feeders
Glass is inherently rust-proof and provides a smooth, easy to clean surface. Borosilicate glass is particularly strong and durable. When choosing a glass feeder, look for one made from borosilicate glass with reinforced seams and leak-proof feeding ports. The main drawback of glass feeders is potential breakage. However, with borosilicate glass constructed properly, that risk is minimized.
Powder Coated Metal Feeders
Powder coating can provide metal feeders with good rust resistance. The process applies a polymer coating using an electrostatic charge. Compared to conventional paint, powder coating creates a tougher, thicker, and more UV-resistant finish. When selecting a powder coated metal feeder, look for these features:
- Thick layer of powder coating, at least 2 mils
- UV-resistant powder coating formula
- Coating on interior and exterior surfaces
- Protection of seams and crevices
Key Tips for Rust Prevention
Here are some additional tips for preventing rust in hummingbird feeders:
- Clean the feeder thoroughly and regularly with a bottle brush, mild soap and water. Allow to fully dry before refilling.
- Rinse thoroughly after cleaning to remove any soap residue.
- Use distilled or filtered water to fill the feeder. Tap water may have minerals that deposit on surfaces.
- Don’t leave nectar sitting for more than a few days. Stagnant nectar promotes rust and bacterial growth.
- Store the feeder dry during winter or periods of disuse. Remaining nectar can spoil and eat away at surfaces.
