We installed two hummingird feeders in our garden, and the visitors are already comming. But I noticed that "our" little hummingbirds prefer the natural nectar of the pink bushes wich are in full bloom at this time of the year, and ignore the syrup. Beside the fact that natural food is "natural" ( and for that reason preffered), could be a way to tempt the to come back the splendid "oiseaux mouche" ?
