How to Make Hummingbird Food

After several years of buying hummingbird food from stores (shame on me), I decided to do some research on making my own.  Talk about easy..... the basic mixture is one part sugar, four parts water.  Boil the water first, then stir in the sugar, let cool.... that's all there is to it.  Make sure the sugar is pure white cane sugar, don't use honey or molasses.  No dyes are necessary.  Unlike the store versions which are usually red, this nectar is clear.  But the hummingbirds seem to love it.  We now have four battling over the feeder.  They seem to be very territorial.  No more than one will drink from the feeder at a time, and will jealously chase off any hummingbirds that approach the feeder.
