Passive Thermal Shield. All-Weather Protection.
A fully sterilizable, non-electric feeder engineered to act like a thermos for your nectar. Hummers Therma™ insulates the liquid, shielding it from sudden temperature spikes, scorching heat, freezing cold, and direct sunlight. Choose your version:
For Very Hot or Very Cold Days: Standard plastic feeders leave nectar at the mercy of the weather—cooking it in the summer sun or freezing it in winter. Hummers Therma™ maintains a stable temperature longer, preserving the nectar's nutritional quality without the need for power cords.
Why Plastic is a Risk: Did you know that standard plastic feeders can develop pathogenic bacteria and fungi, including Candida? The limitation: Washing them in hot tap water is not enough to kill pathogens. True sterilization requires boiling or microwaving—methods that damage most plastic feeders. The Solution: Hummers Therma™ is built to be 100% sterilizable, ensuring safety in every season
