Hi, George - your recipe (1 part/ounce sugar (white only seems to be the gold standard) to 4 parts/ounces water) seems to be the norm for year round feeding.  I excerpted the following from:

http://www.hummingbirds.net/feeders.html#recipe

For the sake of completeness: another view of syrup concentration appeared in the May 1993 article (link below) by Reed Hainsworth and Larry Wolf, both noted hummingbird researchers. However, it's not clear that the health of the birds was considered, or merely their preferences - like children, hummers may tend to eat more candy than is good for them - and there is still a suspicion that high sugar concentrations can cause liver damage in hummingbirds. When I wrote Dr. Hainsworth asking for a reference to a more rigorously-scientific treatment of his data (i.e., a published paper), his reply dodged the question. Without reflection upon anyone's reputation, I stand by the opinion of the majority of hummingbird researchers, that a 1:4 mixture has been shown to do no harm, and any other formula must remain suspect.
