Our favorite hummingbird feeder because it's the easiest to keep clean. The saucer design comes apart in seconds, a built-in ant moat stops ants, and a raised perch gives you great views.

What is the hummingbird nectar ratio?
One part plain white table sugar to four parts water, by volume. It's close to the sugar content of the flowers hummingbirds feed on.
Do I need to boil the water?
It isn't required, but using warm water helps sugar dissolve, and boiling can help nectar keep a little longer. Let it cool before filling the feeder.
Can I use honey, brown sugar or red dye?
No. Use only plain white sugar. Honey and raw or brown sugars can spoil quickly, and red dye is unnecessary.
How long can I store extra nectar?
Covered in the refrigerator for up to about a week.
