I just fill a "Sport Drink" bottle with 1/3 sugar and 2/3 warm water.
A lot of shaking and it is ready.
I clean my feeder every time I fill it.
I place a small fishing bobber in the feeder to see when empty.
One very hot day I needed to refill. I took my supply out of the fridge.
I refilled and hung it out.
About 30 seconds a hummer landed.
It took a long drink. It jumped up about 6 inches and every feather on its body stood straight out.
It relanded and spent about a minute drinking.
Do you put the nectar in the feeder straight from the refrigerator? I always let mine come up to room temp or close to it before filling the feeders so it doesn't chill them. I know when I raised guinea fowl, cold water could be fatal to the chicks. Their tiny bodies would get chilled from drinking cold water and could kill them. I assume hummingbirds could be affected in a similar fashion so have always let it warm up a bit before filling the feeders. I actually have two sets of feeders and sanitize the dirty ones when I swap the for the fresh set.
i always put mine straight from the fridge to the feeders, and it has never seemed to bother them.
I do the same. It warms up pretty quickly.i always put mine straight from the fridge to the feeders, and it has never seemed to bother them.
