I have a question about feeding hummingbirds that I have not seen addressed in any of my reading materials. I thought the WIBirdNet group would be very helpful here. The question is what is the best water to mix with sugar when feeding hummingbirds. Some folks have city water which can contain chlorine and who knows what else. I have well water which tends to be 'hard water'containg calcium and magnesium. I also can use softened water which does not contain these elements. I thought it might be best to use the 'hard water' because the hummers might get some health benefit from these natural ingredients. But when I do use the hard water, I find that these elements tend to precipitate out within several hours and form a cloudy film at the bottom of the feeder. So what is the best water to use for feeding hummers? Thanks in advance for any advice, comments or insights, Maureen Gross Mukwonago, Waukesha County #################### You received this email because you are subscribed to the Wisconsin Birding Network (Wisbirdn).
