The Rufous Hummingbird, on the other hand, is a popular sight in the western United States. It's remarkable for its longest migration – all the way to northern Alaska – a feat for a bird so small.
Here's a quick rundown of the three most common hummingbird species:
- Ruby-throated Hummingbird: found east of the Mississippi
- Rufous Hummingbird: found in the western United States
- Anna's Hummingbird: not mentioned in terms of range, but described as having a glittering red forehead
These species are quite different, but they all share some amazing characteristics that set them apart from other birds.
Behavior and Habitat
Ruby-throated Hummingbirds are precision flyers, able to fly full out and stop in an instant, hang motionless in midair, and adjust their position with minute control.
They dart between nectar sources with fast, straight flights or sit on a small twig keeping a lookout, bill waving back and forth as the bird looks around.
Male Ruby-throated Hummingbirds aggressively defend flowers and feeders, leading to spectacular chases and dogfights, and occasional jabs with the beak.
To attract these birds to your backyard, consider planting nectar-rich flowers or setting up a hummingbird feeder, as they commonly associate with old fields, forest edges, meadows, orchards, stream borders, and backyards.

Male Ruby-throated Hummingbirds aggressively defend flowers and feeders, leading to spectacular chases and dogfights, and occasional jabs with the beak.
In some areas, they yield to larger hummingbird species, such as those found in Mexico, and to the notoriously aggressive Rufous Hummingbird.
Males give a courtship display to females that enter their territory, making a looping, U-shaped dive starting from as high as 50 feet above the female.
If the female perches, the male shifts to making fast side-to-side flights while facing her.

Habitat
Ruby-throated Hummingbirds inhabit deciduous woodlands of eastern North America and the Canadian prairies. They're also commonly found in backyards.
Old fields and forest edges are familiar territories for these birds. They thrive in meadows, orchards, and stream borders.
On their wintering grounds, Ruby-throated Hummingbirds live in dry forests, where they can be found amidst the scrub and hedgerows.
Wings' Beating Speed

Hummingbirds beat their wings at an incredible 80 times per second, which is why they make a humming noise. This remarkable speed allows them to hover, stop instantly, and fly in different directions with exquisite control.
Their wings don't flap up and down like most birds, but rather rotate in a figure 8 pattern. This unique motion is a key part of what makes hummingbirds so agile and efficient in flight.
If you're lucky enough to have a hummingbird visit your yard, you might notice them resting on a tree or shrub every 15 minutes or so. They prefer plants with small leaves, such as birch trees, butterfly bushes, and honey locusts.
Do Birds See Red?
Hummingbirds can see red due to a unique feature in their retinas, which contain a dense concentration of cones with pigments and oil droplets in shades of yellow to red.
These cones act like filters, heightening color sensitivity to red and yellow, while muting colors like blue.

Migration
Migration is a remarkable journey for Ruby-throated Hummingbirds, with most birds flying across the Gulf of Mexico to reach their wintering grounds in Central America.
Some birds, however, choose to stay in North America, often settling along the Gulf Coast, parts of the southern Atlantic coast, and at the tip of Florida.
What Do They Eat?
When it comes to feeding ruby throated hummingbirds, they have a sweet tooth for flower nectar and insects. Hummingbirds live on a diet of flower nectar and insects, supplemented by food from hummingbird feeders.
You can make your own sugar water at home to fill their feeders. We make our own sugar water (1 part white sugar to 4 parts water) and usually have to fill the red backyard feeder twice a week.
To make the sugar water, simply mix the sugar and water in a pot and heat on the stovetop enough to dissolve the sugar. Mix the sugar and water in a pot and heat on the stovetop enough to dissolve the sugar and allow to cool before putting it into feeders.
Hummingbirds don't need tinted water, by the way. The water itself does NOT need to be tinted. Hummingbirds have remarkable spatial memories and flutter before feeders before they are even hung in the spring.
Here's a quick reference guide to making sugar water for your hummingbird feeder:
- 1 part white sugar to 4 parts water
- Mix sugar and water in a pot
- Heat on stovetop to dissolve sugar
- Allow to cool before filling feeders
Reproduction and Mating
Ruby throated hummingbirds generally mate between March and July, with mid-May being the height of the breeding season.
The males are especially vocal during this time, chattering and making a humming sound caused by their wing movement as they interact with other males.
Hummingbirds are known to be busy during the breeding season, but they do take time to rest and refuel, often visiting feeders and flowers to replenish their energy stores.
Unique Features
Ruby throated hummingbirds have an incredibly high heart rate of 1,260 beats per minute, making them one of the fastest beating hearts in the animal kingdom.
Their high metabolism requires a lot of energy, which is why they need to eat constantly and can be seen visiting feeders as often as every 15 minutes.
One of the most fascinating things about hummingbirds is their ability to hover in mid-air, a feat made possible by their incredibly fast wing movement, beating as fast as 80 times per second.
Fun Facts About Ruby-throated Hummingbirds
Ruby-throated Hummingbirds are incredibly agile flyers, beating their wings up to 80 times per second to hover in mid-air.
These tiny birds can reach speeds of up to 30 miles per hour while in flight, which is quite impressive considering their small size.
Ruby-throated Hummingbirds are the only species of hummingbird that migrates through the eastern United States, with some individuals traveling as far as 500 miles non-stop over the Gulf of Mexico.
Their bright, iridescent feathers are not just for show – they also help to reflect UV light and attract mates.
Ruby-throated Hummingbirds are attracted to flowers with long, tube-shaped blooms, like trumpet-shaped flowers, which allow them to easily access nectar.
Hummingbird Heart Rate Speed
Hummingbirds have an incredibly fast heart rate, beating at 1,260 times per minute. This is likely due to their high metabolic rate.
Their heart rate is so fast that it's almost impossible to comprehend, but it's essential for their survival. They need to pump blood quickly to support their rapid wing movements and long flights.
To put this into perspective, a human heart rate is typically around 70-80 beats per minute, so a hummingbird's heart rate is about 15-16 times faster.
Conservation and Distribution
The ruby-throated hummingbird is a migratory bird that travels from Canada to Central America each year, a journey of over 500 miles.
These birds are known to stop at flowers and feeders along the way to refuel and rest.
In North America, they can be found in gardens and backyards with nectar-rich flowers, particularly trumpet-shaped flowers like honeysuckle and fuchsia.
Ruby-throated hummingbirds are also known to visit feeders specifically designed for hummingbirds, which are filled with a sugar-water mixture.
By providing a source of food and shelter, we can help support the conservation of these incredible birds and their habitats.
