I have been using Google and Google Scholar to try to locate a source for
the often-repeated statement that sugar concentrations higher than 1:4 can
cause liver damage in hummingbirds. No luck, however. Does anyone know where
this idea originated?

 

Meanwhile, here is an interesting article from the May 1993 issue of
WildBird magazine, available online, that raises questions about the
traditional 1:4 concentration: "Hummingbird Feeding", by Reed Hainsworth,
Phd, and Larry Wolf, Phd. http://www.hummingbirds.net/hainsworth.html
