Ruby-throated hummingbirds soon will be back. Their tiny size, acrobatic flying ability and eagerness to use nectar feeders make hummingbirds one of America’s favorite backyard birds. This fascination always triggers a flurry of mail, so let me anticipate the most common hummer questions I will get over the next month.

Q. How many species of hummingbirds live in the east?

A. Only the ruby-throated hummingbird nests regularly east of the Mississippi River. The female lacks the male’s bright, red throat, so some people mistakenly believe two species visit their feeders.

Q. When should I put up my hummingbird feeder?

A. My earliest record for hummers is April 22, but I put up a feeder April 15, just in case. To track ruby-throat’s northward journey, visit www.hummingbirds.net/map.html. The first ruby-throats of the year arrived on U.S. soil Feb. 20 in Louisiana. This week, there have been hummers reported as far north as Maryland, Kentucky and Missouri.

Q. What’s the recipe for nectar?

A. Add one part table sugar to four parts hot or boiling water. Hot water simply allows the sugar to dissolve faster. Stir, cool at room temperature and store in the refrigerator. Red dye is unnecessary. And never use honey as a sweetener. Honey promotes a fungal disease that can kill hummers.

Q. How can hummingbirds survive if they just sip sugar water?

A. If they ate just sugar water, they would not survive. Sugar is nutritionally empty, but rich in calories. Hummers drink nectar for the calories — the energy. They obtain nutrition by eating soft-bodied invertebrates such as spiders, flies, aphids and gnats. Nectar probably makes up less than half their total diet.

Q. Is there a “best” nectar feeder?

A. Any red nectar feeder will catch the attention of hummingbirds, but it must be easy to clean. Rinse the feeder and change the nectar every three days, and wash it with hot, soapy water once a week. Aspects and Droll Yankees are two manufacturers that make quality nectar feeders.

Q. What else I can do to attract hummingbirds?

A. Plant red, tubular, nectar-bearing flowers. Trumpet honeysuckle, trumpet creeper, cardinal flower, jewelweed and bee balm are all hummingbird favorites.

Another way to provide food is to offer overripe bananas. Hummers have a field day feasting on the fruit flies that inevitably appear.

Q. How can I keep ants out of my hummingbird feeders?

A. An ant guard is an inexpensive moatlike saucer from which you hang the feeder. Fill the moat with salad oil or dish detergent, and ants get trapped in the liquid when they try to cross the moat. Some nectar feeders come with built-in ant guards.

Q. Can you briefly outline a hummingbird’s nesting season?

A. Males return before females in the spring and establish feeding territories. Fiercely protective of their nectar sources, males seem to spend more time chasing competitors away from “their” food supplies than actually feeding.

When females arrive a few days to a week later, courtship begins. The male performs aerial displays while the female watches from a nearby perch. He flies back and forth in a wide semicircle. After mating, the promiscuous male goes on to find another female.

The female builds a tiny nest on a small, horizontal branch 5 to 20 feet above a stream or other open spot. She begins by using sticky spider silk to fasten bits of leaves or bud scales to the branch. Over a span of days, she builds an elastic cup about the size of a walnut. She lines the nest with soft plant fibers and camouflages the outside with bits of lichens.

After laying two tiny eggs, the female incubates them for about 16 days.
