Ruby-throated Hummingbirds Mating Habits

An understanding of the Ruby-throated hummingbirds nesting, mating, and feeding habits may aid you in attracting and keeping these small wonders in your backyard garden and around your bird feeders.

These birds may be small but someone forgot to tell them. These tiny birds will staunchly defend their territory at the bird feeder during the fall migration.

Males will chase other males away letting only his females and young to feed. (maybe not even them)

How to Make Humming Bird Sugar Water Mixture

A feeder filled with sugar water will attract this relatively tame visitor. Just mix 1 cup white sugar with 4 cups of water.

Should I Boil the Homemade Hummingbird Food

You can boil the mixture 3 or 4 minutes to remove any impurities if you like but it's no longer recommend. The most important chore is to clean your feeders throughly every 3-4 days. and more often during hot temperatures.

I recommend if you're going to boil the water to boil without sugar first. The amount of water will be reduced during boiling and the nectar will be more concentrated.

The 1 part sugar to 4 parts water is what most closely mimics nectar in the wild. While I know people use more sugar than they should, it's not healthy for the birds just because they like it. Too much sugar is not good for anyone.

Feeding Habits What Hummingbirds Eat

Hummingbirds must eat all day long just to survive. In addition to nectar from flowers and your sugar water feeder, these birds eat small insects, beetles, ants, aphids, gnats, mosquitoes, and wasp.

As you can see, it's to your advantage to attract these jewels to your backyard to maintain insect populations. These wild forms of protein are what they feed their young.

When Do I Take My Hummingbird Feeders Down

Many ask the question "When do I need to take my hummingbird feeder down?" A common myth is that leaving your feeders out too long will cause the hummingbirds to stay longer than they should. This just isn't true.

The recommended best time to stop feeding hummingbirds is two weeks after you no longer see them visiting your yard and feeders.

As long as you still see them visiting keep providing for them. This will allow them to store fat resources for their long migration.

If a freeze is predicted, bring your feeder indoors for the night and return it as early in the morning as possible. They need to refuel after a cold night.

How Do Hummingbirds Stay Warm On Cold Nights

We're often ask "how do hummingbirds stay warm at night?" Well, along with the normal things birds do such as puffing out feathers for better insulation and finding sheltered locations to roost, these birds have the ability to reduce their temperature and slow their metabolisom down.

This slowed down metabolisom is referred to as "Torpor", Example in photo below.

Think of it as a mini hibernation just to get through a cold night. They are not the only birds capable of doing this, Doves, Common Whip-poor-wills, some swifts, and other birds have this ability.

We get emails from visiters who find these birds in a state of torpor and hanging upside down on the feeder.

Othertimes, early in the morning, some people have picked them off the feeder thinking they were ill.

It's is always best to wait and see. Let them come out of this state at their own pace so that no harm is done to the bird.

Hummingbird Nesting Habits - When Do They Nest

Hummingbird Nest

So when do Ruby-throated Hummingbirds Nest? Depending on whether they breed in the Gulf states or farther North determines when your most likely to see them.

The Gulf coast may see males arriving in late February and New Brunswick may have both male and female by late May. For most of the U.S. anytime between April and late May is when you can expect them.

When females arrive to their territory they select a nest site and begin building the nest without any help from a male.

An interest side note, the female is the only one that provides care to the young.

When looking for their nest, you'll need a keen eye. Its nest is a cup of plant down and spider web, covered with flakes of lichen, placed 5-20 ft. above ground. Look for a horizontal limb with a slight downslope.

Since they use spider webbing for nest building they sometimes can get trapped in larger webs.

Two white eggs are incubated for about 20 days by the female hummingbird and the young will leave the nest 20-22 days after hatching.

The female will continue feeding the young after leaving the nest for about a week

These birds don't reuse a nest from season to season but may refurbish and reuse it in the same season for its second brood.

They often return to the same territory from year to year and maybe to the same shrub or tree.

Nest are very small and are easily destroyed by winter weather but it's best to leave them intact when you find one.

May attempt 2 broods each season.

Here are a few interesting facts and behavioral habits:

  • In spring, the male defends his territory of about 1/4 acre.
  • In dive displays, he flies in a U shape, rising 10-40 ft. on each side.
  • After mating, the female builds the nest and raises the young alone.
  • The flight speed has been clocked at 25 mph and estimated at up to 50 mph
  • Hummingbirds do not ride on the backs of geese during migration. They migrate on their own power.
  • Generally, adults birds migrate South first, while the young continue to feed and grow before migrating.

Some Ruby-throated Hummingbirds migrate 600 miles across the Gulf of Mexico. During fall they will store enough fat to double their weight in order to make the long trip.

That's quite a feat for a bird that weighs about the same as 2 1/2 paper clips!

Predators of Ruby-throated Hummingbird

Predators may include: Sharp-shinned Hawk, and American Kestrels. Around feeders they are often attacked by domestic cats. Bees and wasp around feeders can cause harm by stinging.
