Vacuum Insulated Hummingbird Feeders
Keep your nectar fresh for longer. Moldy and infected nectar can make hummingbirds sick.
Also delays nectar from freezing.
INsulation for all temperatures
In Hot Weather
When temperatures reach 85 degrees F /30 C or hotter, you can add ice to the MAX line. This will keep the nectar cool for longer in order to prevent the nectar from spoiling, becoming infected or from burning the hummingbirds' tongues. Check and replace the nectar every 1-3 days, depending on the outside temperature.
In Cold Weather
The insulation will help delay the nectar from freezing. Nectar starts to freeze at 28 F. When temperatures get below 28 degrees F during the day, you can add warm tap water to the MAX line . Bring the feeder in at night so that it can warm up. If the temperature is staying below 28 F every day, replace the warm water each morning. Do not put hot nectar into the nectar dish. Only fill the nectar dish with room temperature nectar.
