ratio of sugar to water
I know that the correct ratio of sugar to water is 1 cup of sugar to 4 cups of water. My neighbor actually uses 1 cup of sugar for every 2 cups of water. She has tons of humming birds. I am currious if this is bad for the birds. I know that they use the sugar to fuel their little wings, and they get a lot of their nutrition from other sources such as insects. However, it occured to me that if they are getting that big a dose of sugar so quickly, they might be inclined to drink less sugar water and be at risk of dehydration.
Does anybody know? Is it bad for them to drink, consistenly, from a feeder that is two parts water to one part sugar? Or is it just a waste of money buying the sugar?
