Ruby-throated Hummingbirds

A sure sign of Spring in Virginia is the arrival of Ruby-throated Hummingbirds. This diminutive bird generally spends the winter in Central America, Mexico, and Florida, and migrates to Eastern North America for the summer to breed. It is by far the most common hummingbird seen east of the Mississippi River in North America.
I have a small garden that contains many flowering, native plants, which both hummingbirds and butterflies enjoy. I also put out one hummingbird feeder on St. Patrick’s Day (March 17th) in anticipation of their arrival.  So far, I have not yet had one that early, but with our climate changing, it’s just a matter of time. But, by mid April I begin to see an occasional male and by May the females have arrived, found a mate, and are building nests. The yard and local parks are buzzing with them!
In May, I put out two additional feeders in different parts of my yard. For the home made nectar I boil 4 cups of water, remove it from heat, add 1 cup of sugar,  stir to dissolve, and allow to cool completely. I DO NOT add red food coloring, as I have read that it can impact their health. As spring turns to summer, I change out the feeder frequently, always trying to keep it fresh.
Ruby-throats are intensely inquisitive and thus easily attracted to feeders, where males in particular typically display aggressive territoriality toward rival hummers, other birds, and even insects such as bees, butterflies, and sphinx moths. They quickly become accustomed to human presence, and will swoop down to investigate red articles of clothing, red patio umbrellas and the like, possibly looking for food.
The female Ruby-throated Hummingbird is not as brightly colored as the male but she most definitely does all the parenting. She builds the nest, incubates the eggs, feeds the hatchlings, and then feeds the fledglings for about 10 days. For a short period immediately after fledgling, a female will tolerate the presence of her own young at a feeder, but they are soon treated the same as other adult birds - as rivals in pursuit of the food necessary to prepare for the fall migration.
I see these Ruby-throated Hummingbirds  in my yard through September. You can see them too! Just buy a feeder, make some nectar, plant a few flowers or hang flowering baskets!
