Should I stop feeding hummingbirds because of the WHL recommendation?

The WHL recommendation applies broadly to all bird feeding, and it's grounded in real concern about disease transmission at poorly maintained feeders. If you're willing to commit to regular cleaning and fresh nectar, the risk profile changes significantly. A well-maintained feeder provides real benefits — especially during migration and in habitat-poor areas.

What diseases can hummingbirds get from dirty feeders?

The most serious feeder-related illnesses are fungal infections (particularly Candida, which causes the tongue to swell), Avian Trichomonosis (throat lesions that prevent swallowing), and bacterial infections from fermented nectar. All of these are dramatically less likely in a feeder that is cleaned regularly and filled with fresh, pure nectar.

Is red dye in hummingbird nectar dangerous?

There is no proven benefit to using red dye — hummingbirds are attracted to the color of the feeder, not the nectar. Some research suggests red dye may cause organ damage over time. The safest and simplest approach is to use clear nectar made with pure white cane sugar and water.

How often do I really need to clean my hummingbird feeder?

Every 2–3 days in temperatures below 80°F, and every 1–2 days when it's hotter. In peak summer heat above 90°F, daily changes and cleanings may be necessary. Nectar can ferment before it visibly appears spoiled, so a schedule is more reliable than visual inspection.

Do feeders cause hummingbirds to become dependent and forget how to find natural food?

No. Hummingbirds are opportunistic feeders with excellent memories and natural foraging instincts. They use feeders as one food source among many and continue to visit flowers and hunt insects regardless of feeder availability. Feeders don't create dependency any more than a fruit tree in your yard creates dependency.

What's the safest type of feeder to use?

Saucer-style feeders are generally considered safer and easier to maintain than bottle-style feeders. They have less surface area exposed to air, are easier to disassemble and clean thoroughly, don't leak as easily, and keep nectar farther from the ports (making it harder for bees to reach). Glass feeders may also be easier to clean than some plastic ones.
