How do you know that it's the composition of the solutions
that causes this preference?  How did you eliminate such
variables as the locations and designs of the feeders, the
relative sweetness, temperature, and so on?

Pardon my skepticism, but I had a course in experimental
design once, and it convinced me that it is extremely
difficult to design an unbiased experiment.  Anecdotes
like this are a long way from proof.
