Please be careful how you prepare Hummingbird Nectar. We noticed a hummingbird that was unable to retract her tongue due to fungal spores that had germinated on her tongue or in her gullet caused by folks mixing honey or anything other than plain white sugar with water. She will die because she can no longer feed. If you have feeders, please use only plain white sugar in your mixture of one part sugar to four parts water. No organic or raw or brown sugar, no powdered sugar, no honey, no artificial sugar. Use only the plain white sugar/water mixture which is most similar to actual flower nectar. Donâ€™t use any toxic red color liquids such as Koolaid, etc. Change the sugar water mixture every couple of days, especially during high temperatures, as it will start to ferment if it sits out for days on end. If you canâ€™t or wonâ€™t do this, please do not put out a feeder at all.
