rgb(0, 0, 0); font-family: 'Times New Roman'; fon The relationship of hummer-plants and hummingbirds has established itself over a long period of co-evolution. That the sugar concentration in the nectar of ornithophilic plants is in the 20-30% range (and different from the one found in insect pollinated plants) sure bears some significance for both the plants and the hummingbirds. So I would just stick with the widely used 1:4 ratio and not start some pointless experiments.
