Hot temperatures can cause moldy nectar & make hummingbirds sick.
Insulation helps keep it cool to help prevent infection.
The BPA free plastic lid has built in perches and flower ports that are small enough to prevent bees from entering.
The nectar dish holds up to 8 ounces and mounts inside of the stainless steel container. Fill it to the top with nectar. Easy to clean all parts.
Food grade vacuum insulated stainless steel.
In hot weather, you can add ice to the bottom of the container underneath the nectar. This will keep the nectar cool for longer in order to prevent the nectar from spoiling, becoming infected or from burning the hummingbirds' tongues.
The insulation will help delay the nectar from freezing. When temperatures get below freezing during the day, you can add hot tap water to the container underneath the nectar.
It ships from Bellingham, WA by USPS or UPS ground. It will usually process in 1 day and then ship to your address in 2-7 days, depending on location in the U.S.
Place a saucer with water underneath the feeder if it is placed on a surface. Use an ant moat if hanging the feeder.
The nectar dish holds 8 ounces of nectar (sugar water) and it sits on top of a ledge inside of the insulated container. The hummingbirds will be able to reach and drink from the top of the nectar dish. There might be a small amount of extra nectar at the bottom of the dish that they cannot reach. This was designed so that there is a larger volume of nectar in order to help maintain its temperature inside the feeder.
You should only add hot water to the feeder when the temperature outside during the day is less than 28F. Hot tap water reaches 120F and it can safely be added underneath the nectar dish without overheating the nectar. The MAX line is 1/4 inch below the bottom of the nectar dish. During testing of the feeder, the nectar temperature reached 90 F after 30 minutes in 32 degrees and dropped to 80 F after 60 minutes and continued cooling slowly.
According to research, hummingbirds metabolism may speed up when they drink from nectar over 100F so it is important to keep the nectar under 100.
If used properly, the nectar will never go over 100F when set outside in 28F or less.
Hummingbirds are able to drink nectar down to freezing temperatures. Sugar water that is exposed to high temperatures has been found to become infected faster than sugar water at cooler temperatures. Fungal infections can be deadly for hummingbirds.
The stainless steel is powder coated with a weather resistant paint. The lid with the feeding holes and perches is plastic. The hummingbirds perch themselves on top of the plastic. There are no exposed metal parts.
There is a built in hook in the lid of the feeder to use with your own hanger. Alternatively, you can place the feeder on a surface and use a plant saucer filled with water underneath it to act as an ant moat.
