OK, so I haven't seen a hummingbird yet this year, but they're coming. They have been sighted in Texas and are heading back this way. Drought conditions being what they are, some supplemental food is going to be important. I cleaned out my hummingbird feeder and set it out this morning (this picture is from last summer, not this morning.)
There is no need to spend a lot of money on nectar. You have a red feeder, the birds don't need red nectar (you don't see red nectar in your flowers, do you?) Give your wallet/purse a rest and use the following recipe: 4 parts water and 1 part sugar. You can dissolve the sugar in the water without boiling, but most of us do boil the water first--if nothing else as an extra measure to kill any bacteria that might remain in your feeder after cleaning. If you made too much, you can keep the extra in your refrigerator until you need it.
It is important you change your feeder nectar frequently--at least every 3 days. Perhaps more often in the hottest part of the summer. If the nectar looks cloudy, you definitely need to change it.
I encourage you to put out the welcome mat for your hummingbirds as soon as possible. Even if you don't see them visit, it is quite possible they are early in the morning or late in the evening. I hope however, you have the chance to enjoy these amazing little birds.
