We haven’t seen a hummingbird in a couple of weeks, so I’ll probably be taking our hummingbird feeders down later today. Very little, if any, sugar water has been consumed since the last time they were filled.
On the subject of sugar water, we use a 1:4 mixture in our feeders most of the year. If swarms of bees show up, we’ve found that cutting the concentration to 1:6 causes them to lose interest. Hummingbirds still like it, but the bees go somewhere else.
When mixing up the solution, we always add a few drops of red food coloring, and that is the source of today’s mystery. We have three feeders out and the sugar water in the two plastic ones is still bright red, but in the one with a glass reservoir the solution is clear. I noticed a few days ago that it was pink, but today it looks as though we never added any food coloring at all.
