What’s the best recipe for hummingbird nectar?

The sugar content of flower nectar varies—it’s roughly comparable to sugar-water mixtures ranging from a quarter to a third cup of sugar per cup of water.

During hot, dry weather, when hummingbirds risk dehydration, it’s best to make your mixture no stronger than a quarter cup of sugar per cup of water.

But during cold, rainy spells, make the mixture a bit stronger, up to about a third cup of sugar per cup of water This won’t hurt your birds and may help them.
