Well hello there, my its been a long, long time... Because of the scorching heat in Katy, Texas, 105 degrees today, we hung up a hummingbird feeder. Our Hamelias usually provide enough nectar to suffice the nesting hummingbirds in our neighborhood but, with the drought and heat they wilt before noon even if I water them. Nectar recipe is 4 to 1. One part sugar to four parts water. Stir 1/4 cup sugar into a warm 1 cup of water until it dissolves. I added ice cubes to cool it down just because of the heat outside. The hummers will be drawn visually to the red flowers so, there is no need to add red food coloring at all. Food coloring is not good for them to injest. Not good for children and not good for hummers. The two hummers visiting our feeder spent an awful lot of time trying to push each other out of the way. I wish I could tell them please don't fight there is plenty for everyone to enjoy. I rinse and refil...
