Hummingbird Facts:

There are 16 species of hummingbird. Only the Ruby-throated hummingbird lives throughout the eastern half of the United States and most of southern Canada.

When the Ruby-throated Hummer migrates home, the male usually returns to the breeding area ahead of females and starts establishing his territory around nectar-rich flowers. Their territory size varies with the density of flowering plants and nectar supply, but an average size is about 1/4 acre. If the flowers finish blooming, the male may shift his territory.

The male Ruby-throated hummer can be identified by the dark burgandy band under his throat. The female's throat is gray. The Ruby-throated hummingbird weighs 3 grams. Their (all hummingbirds) heart represents 2.4 percent of their body. The hummingbird egg is less than 1/2 inch long. The average hummingbird consumes half its weight in sugar each day. They feed 5 to 8 times an hour for about 30 to 60 seconds at a time. A male Ruby-throated hummingbird's wings can beat 78 times per second during regular flight and up to 200 times per second during a display dive A nesting hummingbird takes 250 breaths per minute. They can fly forward, backward, and even upside down briefly.

They bathe by flying through sprinklers or spray from waterfalls. They may also flutter in wet foliage or dip in a shallow puddle.

Ruby-throated hummingbirds fly 500 miles nonstop across the Gulf of Mexico on their migration. Before starting, they increase their body weight by 50 percent, storing energy as fat to burn while crossing

Feeders:

There are quite a few commercial hummingbird feeders on the market. Most of the feeders have flower patterns or red parts on them so that they are attractive to hummingbirds.

There are basically two designs.

The inverted bottle that empties into a reservoir with feeding holes or the inverted bottle with a rubber stopper and glass tube coming out the bottom. The vacuum created at the top of the bottle is what keeps the liquid from draining out.

The other type of feeder is simply a container with holes in its cover.

Some feeders have perches, some don't. If your feeder doesn't have a perch, the hummingbird will hover to drink and when they want to perch they will fly to a nearby shrub or dead limb. Hummingbirds take frequent breaks from their energy-intensive hovering flights. In fact, one study found that they spend over 60 percent of their time perched. One problem with perches is that larger birds may use the perches to get at the sugar water and exclude the hummingbirds. If this happens, simply remove the perches.

Try whichever type you like; however, it's best to start out small or with a small amount of liquid in the feeder so that liquid doesn't sit over a couple of days in the feeder.

Initially, the best place to put feeders is near flowers that attract hummingbirds. Or, even better, where hummingbirds have been feeding (see "Hummingbird Gardening").

Placement: Place the feeder where it will be protected from the wind and where there is some shade (*the hot sun will cause the sugar solution to spoil more quickly).

Number of Feeders: Watching hummingbirds is very entertaining. Hummingbirds can be very aggressive around food sources and try to keep other hummingbirds away. A pecking order may form among the hummers at the feeder with some birds being dominant.

To reduce competition, try putting up two, three or four feeders. It's better if each is out of the sight of the others.

Homemade Feeders: Pill vials, test tubes, or small jars painted red, hanging or staked, can be used. Water bottles sold in pet shops for guinea pigs or caged birds decorated with something red to attract the hummers can be used.

Sugar Solutions:

Flower nectar contains 3 types of sugar - sucrose, glucose, and fructose - it is mostly sucrose. Taste-test experiments revealed that sucrose was preferred by most hummers over other sugars.

HOMEMADE MIXTURE:

1 part sugar (not honey) - (artificial sweeteners have no food value. Honey ferments faster and can cause a fungus that affects hummingbirds tongues and can be fatal.)

4 parts water.

Boil for 1 to 2 minutes. Cool. Store extra in refrigerator.

The 1 to 4 ratio approximates the ratio of sugar to water found in flower nectar which on average is 21%. If you increase the sugar, it may be hard for the birds to digest. Boiling the solution helps retard fermentation.

Sugar-and-water solutions are subject to rapid spoiling, especially in hot weather. DO NOT leave sugar and water solutions in the feeder over 48 hours when the temperature is over 60 degrees.

COMMERCIAL MIXTURES:

Some of these mixtures come in powder to which you just add water. Others are already mixed as a liquid - containing pure water, nutrients, vitamins, and minerals - to which you just add the sugar.

Feeders Maintenance

Wash feeders out in very hot water every 2 to 3 days. You may add some vinegar to the hot water to remove mold, or, for really tough cleaning jobs, use a tiny amount of Clorox, making sure to rinse the feeder out thoroughly. If necessary, scrub hard-to-reach spots with bottle brushes and pipe cleaners. If the weather is particularly cool, it may be alright to wait slightly longer than 3 days to clean feeders. In hot weather (over 60 degrees F), pathogens in the feeder solution can multiply rapidly and feeders should be cleaned every 2 days and refilled with fresh solution.

When to put up feeders: Feeders should be up in time for the arrival of the hummingbirds. Arrival times vary depending on where you live. In North Carolina, a few hummers arrive by mid-march. But we do not see many until late March.

Ruby-throated hummingbirds are generally the only breeding variety found in the eastern half of North America. However several western species may wander east especially in late fall. Ruby-throated hummingbirds spend the winter in southern Mexico and return to the Cape Fear region by flying across the Gulf of Mexico through Alabama or Florida, Georgia and South Carolina. In the lower South, arrival may be as early as January or February; in the North, it may be as late as April or May.

When to take down feeders: Contrary to belief, maintaining feeders in the fall does not prevent the hummingbirds from migrating.

In many areas, hummers begin migrating even when there are still flowers in bloom and insects available. Males generally migrate several weeks ahead of females and immature birds. Species that live in the same area often migrate at different times regardless of the food supply. They more likely to time their migrations according to day length or photoperiods. Migrating hummingbirds may actually be helped by the feeders that are left up; as they may get extra energy they need for their long flight.

In certain parts of the country hummingbirds do not migrate. On the West coast, the Southwest, and a few places in the Southeast, hummingbirds can be found in winter. In Ramsey Canyon, Arizona, there have been reports of feeders being visited every 20 minutes in a snowstorm. In severe weather conditions, the sugar water will have to be warmed to keep it from freezing.

The Ruby-throated hummingbird generally migrates Southward in late July to late October.
