So we are getting hummingbirds at our hummingbird feeder outside the living room window. (which we id'ed in our bird book, ruby throated hummingbird). The box the feeder came in says that if the feeder goes dry, your hummingbirds will not ever come back. We bought the store-brand sweetener stuff, and we thought it would be red, but it's clear. Can we put food coloring in there? Or will that kill the birds?
And how is this photo related? We are trying to get a pic, no such luck yet
Thank you!
