We have seven feeders up now. Three of these feeders are shared with Western Orioles (Scotts Orioles). The Orioles visit often and do not drink a lot, however in total we do use 8 cups of nectar daily. We use one cup cane sugar to four cups of boiled water, mixed daily in 8 cup batches. The clear nectar does not seem to attract bees as much as the red nectar. In the spring and fall when the migrations come through, 9 to 10 feeders are needed and this lasts a month or so. I enjoy the humming bird swarms in the yard.
