I've had a hummingbird feeder for many years. It holds one fluid cup of sugar water. We have a number of hummers visiting. I am surprised that this cup of sugar water tends to disappear in a week or so, and I have to be a little skeptical that those tiny birds could drink so much. But it can't be evaporation, because there is no crystallized sugar left behind. So do these guys really chug a lot? How much does a hummingbird drink every visit? If it's just a matter of wetting their long tongue, it can't be that much. Then again, if they actually SUCK LIQUID, it could be a lot more.
