It's always the same feeders, in the same locations, with only the contents changing. The two feeders always have slightly different contents (I switch between all three Perky-Pet nectars and the two feeders always each have a different nectar). The "Light" nectar is *always* consumed faster, no matter which of the two feeders contains it.

Try }using warm water, or stirring a lot. I never said it wasn't possible to get sucrose completely into solution. I simply stated a preference for the finer granules in the Perky-Pet *because* they dissolve easier and faster. My sources are direct eyeball observations of store-bought granulated sugar and Perky-Pet nectar. Or are you claiming that undissolved sugar is harmless to hummers? -Pete Zakel (phz@cadence.com or ..!{hpda,versatc,apollo,ucbcad,uunet}!cadence!phz)
