As a physiologist who has studied hummers for 40+ years I agree with Sheri’s
assessment of surgar concentration for feeder solutions. Frankly, I get so
many people who ask me why their neighbors have hummers and they do not. My
typical response is that most people make their feeder solutions 4:1, but if
they startt making theirs 3:1 they will no longer be short of birds. Works
most of the time. The other advantage of a 3:1 solution is that it will
depress the freezing point of the solution a bit.
Cheers,
Don
