Delaware Hummingbirds: 6 Awesome Documented Species

This article identifies all hummingbirds documented as seen in Delaware and where they are seen in the state. It further identifies if that specific hummingbird species is a year-round resident, a seasonal visitor, or a rare vagrant hummingbird seen in Delaware.

There are six species of hummingbirds documented as seen in Delaware.
Delaware hummingbirds, listed in order of frequency seen are Ruby-throated, Rufous, Allen’s, Calliope, Black-chinned, and Broad-tailed hummingbirds.
Anna’s hummingbirds are not a documented species seen in Delaware, but are included by some websites as a Delaware hummingbird.

Top Google-ranked websites have recognized one additional hummingbird as a Connecticut hummingbird, the Anna’s hummingbird, despite the fact that there are just six species sightings recorded on a national hummingbird sighting map.

These are the Delaware statistics at the end of 2023, as reported by eBird.org.

There are no hummingbirds classified as year-round residents in Delaware.

This hummingbird classification is defined as year-round residents residing in Delaware 365 days a year.

Contrary to popular belief, hummingbirds can withstand far lower temperatures than most people would expect.

Some banded hummingbirds have been observed at temperatures as low as -9 degrees Fahrenheit with a wind chill of -36 degrees Fahrenheit, according to eBird.org.
See my article: 3 Reasons Why Hummingbirds Are Banded

There is one Delaware hummingbird, the Ruby-throated hummingbird, that is classified as a seasonal hummingbird.

Hummingbirds that fit within this category are those that migrate through Delaware on a spring or fall emigration basis.

Hummingbirds move south to spend the winter in Mexico and Central America in the fall, after migrating north in the spring to reproduce.

Due to their preference, an ailment, or advanced age, certain seasonal hummingbirds may spend the whole winter in the state.

Ruby-Throated Hummingbirds:

RUBY-THROATED HUMMINGBIRD – (Archilochus colubris)

Conservation Status: Least concerned
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Apodiformes
Family: Trochilidae
Genus: Archilochus
Species: A. colubris

Scientist Carl Linnaeus of Sweden is credited with giving the Ruby-throated hummingbird its scientific name. He initially classified the species as “Trochilus colubris.” Its name was revised more than a century later when German botanist Ludwig Reichenbach classed it as “Archilochus colubris,” which is now its scientific name and means “sky spirit/sun-god bird” or “top thief.”

Male Ruby-throated hummingbirds:
The beautiful iridescent blood-red gorget of male Ruby-throated hummingbirds ends at the neck.
His distinctive features are black wings, a light gray underbelly, and a dull metallic green topside.

The Ruby-throated hummingbird is a tiny species of hummingbird, measuring 2.8 to 3.3 inches in length and weighing less than 4.5 grams, or two U.S. dimes.
They live for three to five years on average.

The metal plate that shields the wearer’s throat during combat to prevent injuries is the inspiration behind the name of the gorget on a male hummingbird. This name is acceptable and fitting to characterize the physical characteristics of male hummingbirds, since they fight fiercely for their own territory.

Female Ruby-throated hummingbirds:
Ruby-throated hummingbird females are usually larger than males, with a white throat stippled with light spots.
Ruby-throated hummingbird’s life expectancy is roughly three to five years.
The oldest female Ruby-throated hummingbird on record, at nine years old, is nearly twice as old as the male life expectancy.

99% of all Delaware hummingbird sightings will be Ruby-throated hummingbirds.
On average, out of 10,000 hummingbird sightings in Delaware, 9,861 will be of the Ruby-throated hummingbird
.

The Ruby-throated Hummingbird migrates via two different routes in the spring and fall.

The first migration route takes them directly, via the Gulf of Mexico, southwest to Mexico, where they travel nonstop and exhaustingly until they reach Central America for the winter.  Over 500 miles is the flight distance over the Gulf of Mexico. Despite being the direct “short” route, these birds must overcome many difficulties.
The total direct flight from Dover, Delaware to Panama City, Panama is 2,092 miles.

Not being able to rest, not having access to food or fuel, and needing to steer clear of the severe tropical Atlantic hurricanes while traveling to their destination are some of the challenges faced when flying over the Gulf of Mexico. To exacerbate the situation, they migrate during the night or are conducting a “Red-eye flight,” depending on your point of view.

Even though both sexes double their body fat before beginning their arduous transoceanic migratory pattern across the Gulf of Mexico, researchers think that males’ energy consumption is more taxing due to their small stature.

The second land migration path is 4,351 miles long and follows the Gulf of Mexico’s shoreline. Even though there are fewer guarantees of food sources along the way, taking the “long” route gives them the chance to stop and replenish.

Scientists are unclear and continue to investigate why one group of birds would prefer to take one route over the other.

There are six Delaware hummingbirds classified as rare or vagrant hummingbirds. They are the Rufous, Allen’s, Calliope, Black-chinned, Broad-tailed, and Anna’s hummingbirds.

There are no Anna’s hummingbirds documented by eBird.org as seen in Delaware, however, a top Google-ranked site adds this bird to the list.

Hummingbirds that live in a group outside of their typical geographic range are classified as belonging to this category. These hummingbird species not only span a vast range of distinct geographic areas, but they are also known to occasionally interbreed, giving rise to hybrids.

Although they are not in their usual range, reports of seeing these hummingbirds in Delaware have been made.

Rufous Hummingbirds:

RUFOUS HUMMINGBIRD – (Selasphorus rufus)

Conservation Status: Near threatened
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Apodiformes
Family: Trochilidae
Genus: Selasphorus
Species: S. rufous

The Latin word rubrum, which means “red,” is the source of the Rufous hummingbird’s name due to its reddish-brown color.

Male Rufous hummingbirds:
The orange-red gorget of a male rufous hummingbird is iridescent, and their tail and sides have a rusty hue. Their underside is beige to white, and their bill is black. 

Along with chocolate brown dorsal feathers, males can also have green plumage with green spots on their rustic-looking backs or on the summit of their heads.
They weigh 3.2 grams and range in length from 2.8 to 3.5 inches.

The metal plate that shields the wearer’s throat during combat to prevent injuries is the inspiration behind the name of the gorget on a male hummingbird. This name is acceptable and fitting to characterize the physical characteristics of male hummingbirds, since they fight fiercely for their own territory.

Female Rufous hummingbirds:
The female Rufous hummingbird is less colorful than the male because it lacks a gorget and iridescent feathers. In the wild, confusion may arise, though, because certain females have stippling or color specs along their throat line that resemble juvenile characteristics.
They are slightly larger than the males in anticipation of producing offspring.

Juvenile Rufous hummingbirds:
In the wild, juvenile Rufous hummingbirds and Allen’s hummingbirds are nearly identical in terms of color and behavior. Therefore, range rather than appearance is used to establish identity. The juvenile male Rufous’s rustic appearance is attributed to the iridescent orange dots on their neck.

0.65% of all Delaware hummingbird sightings will be Rufous hummingbirds.
On average, out of 10,000 hummingbird sightings in Delaware 65 will be the Rufous hummingbird.

Of all the birds in the world, Rufous hummingbirds migrate within the United States for the longest period of time. Every year, they traverse 3,900 miles in a clockwise manner around western America.

This migratory pattern during the seasons coordinates their arrival perfectly while catching nectar and blooming flowers throughout the year, fueling their bodies for their long journey.

In order to support a healthy migration, hummingbird enthusiasts are very beneficial when they cultivate blooming plants to draw hummingbirds and supply feeders with homemade hummingbird nectar. 

These friendly environments offer and guarantee safe trips in addition to a dependable haven for relaxation and refueling while on the road.

A large number of Rufous hummingbirds will choose to move south to Mexico rather than stay in Delaware for the winter. Hummingbirds, however, can withstand far lower temperatures than most people think.

According to eBird.org, through branding practices in Wisconsin, the Rufous and Ruby-throated hummingbirds are documented surviving in temperatures of -9F and wind chills of -36F.

It has even been observed that female mothers may attack squirrels and chipmunks that approach their nest too closely.

Due to their remarkable memory, Rufous hummingbirds have been observed to search for an abandoned hummingbird feeder years after it has been taken down.
Read my article: Hummingbird Adaptation and Remarkable Ability to Locate Food

Because of their unparalleled flying acrobatics, Rufous hummingbirds are fierce competitors at feeders, outmaneuvering all other species.

Rufous hummingbirds easily hybridize and cross-breed with other hummingbird species, such as Anna’s hummingbirds.

IUCN Red List classifies the Rufous hummingbird as “near threatened” because of habitat destruction in the Pacific Northwest.

In British Columbia, during a banding operation, the oldest living Rufous hummingbird was documented at 8 years and 10 months old.

Allen’s Hummingbirds:

ALLEN’S HUMMINGBIRD – (Selasphorus sasin)

Conservation Status: Least concerned
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Apodiformes
Family: Trochilidae
Genus: Selasphorus
Species: S. sasin

The scientific name of the Allen’s hummingbird is Selasphorus sasin.The common name of the Allen’s hummingbird is in commemoration of Charles Andrew Allen (1841-1930), an American collector and taxidermist.

Male Allen’s hummingbirds:
Male Allen’s hummingbirds are green-backed with a green forehead and rust-colored flanks, rump, and tail. When their tail feathers are fanned out you can see their chocolate-colored tips.

The gorget of the male Allen’s hummingbird is an iridescent orange-red, however, in darker lighting, it can appear chocolate brown.
Allen’s hummingbirds are 3.3 inches to 3.5 inches in length and weigh 2-4 grams.

The metal plate that shields the wearer’s throat during combat to prevent injuries is the inspiration behind the name of the gorget on a male hummingbird. This name is acceptable and fitting to characterize the physical characteristics of male hummingbirds, since they fight fiercely for their own territory.

Juvenile Allen’s hummingbirds:
Both male and female juvenile Allen’s hummingbirds first resemble adult females until the male starts to develop the characteristic iridescent feathers of this species of hummingbird.

In the field, they are nearly identical to Rufous hummingbirds due to their striking similarity in colors and disposition.
Therefore, range rather than appearance is used to establish identity.

0.57% of all Delaware hummingbird sightings will be Allen’s hummingbirds.
On average, out of 10,000 hummingbird sightings in Delaware, 57 will be of Allen’s hummingbird.

Male Allen’s hummingbirds engage in a dramatic, fast-paced courtship dance that mimics a pendulum’s swing. Of all the hummingbirds in North America, their territorial dive displays are among the most intricate.
See my article: Hummingbird Dance: 5 Interpretive Explanations

Allen’s hummingbirds, both male and female, are gregarious birds. Other than mating, they do not interact with each other. Allen’s hummingbirds are fiercely territorial and hostile toward other hummingbirds as well as larger predatory birds like hawks, much like Rufous hummingbirds.

Allen’s hummingbirds are primarily found in coastal parts of California and Oregon, USA. They prefer habitats like gardens, forested or shrubby areas, and coastal chaparral. They migrate to southern Mexico in the winter, covering quite long distances for such small birds.

Allen’s hummingbirds are highly territorial, especially the males during the breeding season. They engage in aggressive aerial displays to defend their feeding territories from intruders. These displays include high-speed chases and intricate flight patterns.
See my article: Why Hummingbirds Chase Each Other: Is it Friend or Foe?

Allen’s hummingbirds commonly reside and nest along the west coast and winter in Mexico. Their nesting season is perfectly timed with when the regions have the most rainfall which helps provide prolific nectar producing flowers for their offspring.

Usually found in trees or shrubs, females use plant materials and spider webs to construct tiny, cup-shaped nests. Each time they attempt to reproduce, they lay one to two eggs, which they then incubate for two to three weeks. For several weeks after hatching, the young remain totally reliant on their mother for nourishment and protection until they are able to fly.

In their natural range, Allen’s hummingbirds often visit gardens and areas with bird feeders. They are a favorite among bird watchers and nature enthusiasts for their colorful appearance and lively behavior.

The future of Allen’s hummingbirds, like many species, is closely tied to environmental factors and human influence on their habitats. Habitat loss and the use of pesticides are among the challenges they face. Efforts to preserve natural habitats, along with responsible gardening and the maintenance of bird feeders, aids in their conservation.

Understanding and protecting Allen’s hummingbirds is crucial for maintaining the ecological balance and for the continued enjoyment of future generations who will marvel at this vibrant and lively bird.

In 2004, and again in 2009, the oldest known living Allen’s hummingbird was taken during a California banding program that involved catch and release. She was 5 years and 11 months old at the time.

Calliope Hummingbirds:

CALLIOPE HUMMINGBIRD – (Selasphorus calliope)

Conservation Status: Least concerned
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Apodiformes
Family: Trochilidae
Genus: Selasphorus
Species: S. calliope

Calliope hummingbirds are named after a Greek mythological muse, who represented poetry and eloquence. Calliope means “beautiful voice” in ancient Greek.

Male Calliope hummingbirds:
The long, stunning row of feathers that protrude down the sides of the throat and their iridescent purple cap are characteristics that make male Calliope hummingbirds clearly identifiable.
These hummingbirds, which are 3 inches long and weigh 2-3 grams, have shiny green backs like many others. 

The metal plate that shields the wearer’s throat during combat to prevent injuries is the inspiration behind the name of the gorget on a male hummingbird.

0.10% of all Delaware hummingbird sightings will be Calliope hummingbirds.
On average, out of 10,000 hummingbird sightings in Delaware, 10 will be the Calliope hummingbird.

Like many other hummingbirds, Calliopes use their feathers to manipulate their flight path in order to produce a variety of buzzing noises that serve as a type of language.  

The male will fervently fly back and forth and perform a “U” shaped courtship display to get the attention of the female when she is quietly perched. The male hummingbird will perform a vocal serenade for the female while swaying his body back and forth in front of her.
See my article: Hummingbird Dance: 5 Interpretive Explanations

A breeding area is established by male Calliope hummingbirds, who mate with any female that accepts their wooing.

In terms of social behavior, Calliope hummingbirds are generally solitary, especially outside of the breeding season. They are territorial, with males often defending prime feeding territories from other hummingbirds.
See my article: Why Hummingbirds Chase Each Other: Is it Friend or Foe?

The world’s smallest long-distance migratory bird is the Calliope hummingbird. Their springtime migration patterns resemble those of Rufous hummingbirds. 

Throughout their northward spring migration where they breed, they traverse the Pacific Flyways. On their southbound journey in the fall, they pass through the Pacific and Rocky Mountain Flyways towards their wintering destination in Mexico.

During the breeding season, female Calliope hummingbirds select the tips of pine cones as her building site for her nest. Along with stealing materials from other birds’ nests to build her own, she will also disassemble and recycle previous seasons’ nests. 

Therefore, larger and more aggressive hummingbirds, such as Allen’s and Rufous hummingbirds, frequently chase and attack female Calliopes. Compared to other species, the Calliope keeps a low profile in order to evade these attacks. 

Calliope hummingbirds hybridize and readily crossbreed with other hummingbird species, such as the Costa’s hummingbird.

Calliope hummingbirds are especially susceptible to habitat loss and natural catastrophes like wildfires and climate change because they have a smaller wintering range than other hummingbird species. The oldest known female Calliope hummingbird was twice captured during a 2007 and 2014 banding operation in Idaho. She was 8 years and 11 months old at the time of her capture.

Genus: Archilochus
Species: A. alexandri

The Black-chinned hummingbird’s scientific name is in commemoration of Dr. Alexandre, a French doctor who was the first to discover the species in Mexico.

Male Black-chinned hummingbirds: The royal purple gorget resembling a buttoned-up shirt with a small flash of color right near the neckline is the distinguishing feature of male Black-chinned hummingbirds. The male’s purple gorget or throat in some lighting at times looks entirely black.

Their flanks and backs are metallic green, while their undersides are white. They have a black bill and a forked dark tail.
Their length ranges from 3.25 to 3.5 inches, and they weigh between 2.8 and 5.6 grams.

The metal plate that shields the wearer’s throat during combat to prevent injuries is the inspiration behind the name of the gorget on a male hummingbird.

0.06% of all Delaware hummingbird sightings will be Black-chinned hummingbirds.
On average, out of 10,000 hummingbird sightings in Delaware, 6 will be the Black-chinned hummingbird.

Black-chinned hummingbirds breed to the east of the Cascade mountain range. By employing a decoy tactic, they are known to build their nests close to larger, busier bird nests, hence decreasing the likelihood of predators nearby. 

Of all extant mammals or vertebrates, Black-chinned hummingbirds have the least amount of genetic material known to science. Due to their little size, they run the risk of becoming prey for larger birds that consume insects.
See my article: 10 Common Things That Kill Hummingbirds

Particularly while protecting “their” feeders, hummingbirds come across as the most ruthless sheriff in the area due to their intense territoriality. To defend nectar sources full of blooming plants that attract hummingbirds, they will engage in territorial conflicts.

Although Black-chinned hummingbirds are a territorial species, they will become less aggressive and learn to share if they happen to be in an area with a high hummingbird population and food sources.

Broad-Tailed Hummingbirds:

BROAD-TAILED HUMMINGBIRD – (Selsaphoris platycercus)

Conservation Status: Least concerned
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Apodiformes
Family: Trochilidae
Genus: Selsaphoris
Species: S. platycercus

The scientific name of the Broad-tailed hummingbird is Selasphorus platycercus. This species got its common name from the notably broad tail of the males, which is a distinguishing feature among hummingbirds.

This broad tail, when combined with the hummingbird’s flight patterns, creates a distinctive trilling sound that is also a characteristic of the species. The combination of visual and auditory traits played a significant role in the naming of this bird.

Male Broad-tailed hummingbirds:
An iridescent ruby-red gorget is seen on male Broad-tailed hummingbirds. Males and females alike, the Broad-tailed hummingbird is characterized by its green upperparts, light underbelly, vivid white eye rings, and widely rounded tails.
They have a medium build, measure from 3.3 and 3.8 inches in length, and weigh 3.6 grams.

The metal plate that shields the wearer’s throat during combat to prevent injuries is the inspiration behind the name of the gorget on a male hummingbird. This name is acceptable and fitting to characterize the physical characteristics of male hummingbirds, since they fight fiercely for their own territory.

Juvenile Broad-tailed hummingbirds:
Male and female juvenile Broad-tailed hummingbirds initially resemble adult females until the male starts to develop the iridescent feathers that are characteristic of this species of hummingbird.

Baby Broad-tailed hummingbirds:
Baby Broad-tailed hummingbirds are easily identified by their undertail coverts, which are white fluffy feathers near their bottom that will disappear as they age.

On average, out of 20,000 hummingbird sightings in Delaware, only 1 will be of the Broad-tailed hummingbird.

The Broad-tailed hummingbird travels frequently to the United States near the southern Mexican border.

They have a migrant and non-migrant population that begins in the south of Mexico. The ones that migrate north to breed will do so during spring migration and will pass through Arizona, Colorado, Wyoming, Idaho and reach as far north as Montana. 

Once the breeding season is complete, Broad-tailed hummingbirds will depart and begin their southbound fall migration to winter in Mexico and meet up with their non-migrant population.

The Broad-tailed hummingbird favors habitats in the understory of mature forest woodlands such as pine and oak groves. They chose to nest on the branches of trees and have been known to return to the same nesting ground each year, roughly 70% of the time.

Their breeding time coincides with the peak time of flowering native plants for maximum food resource availability. Their favorite nectar-producing flower plants include Red Columbine, Indian Paintbrush, Sage varieties, Currants, and Scarlet Mint.

Broad-tailed hummingbirds hybridize and readily crossbreed with other hummingbird species, such as the Costa’s hummingbird.

In terms of social behavior, Broad-tailed Hummingbirds are generally solitary, especially outside of the breeding season. They can be territorial, with males often defending prime feeding territories from other hummingbirds.
See my article: Why Hummingbirds Chase Each Other: Is it Friend or Foe?

The Broad-tailed hummingbird has suffered a decline in population since the 1990s, but presently, its population is stable, and it has been shown to have adapted to human habitat encroachment.

The oldest living Broad-tailed hummingbird, a female, was 12 years and 2 months, recorded during a capture and release banding operation in Colorado.

Anna’s Hummingbirds:

There are no Anna’s hummingbirds documented by eBird.org as seen in Delaware, however, a top Google-ranked site adds this bird to the list.

ANNA’S HUMMINGBIRD – (Calypte anna) 

Conservation Status: Least concerned
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Apodiformes
Family: Trochilidae
Genus: Calypte
Species: C. anna

The Anna’s hummingbird, scientifically known as Calypte anna, gets its common name from Anna Masséna, the Duchess of Rivoli.

Male Anna’s hummingbirds:
In North America, male Anna’s hummingbirds are the only species of hummingbirds with a red crown. Their predominant colors are magenta, gray, and green.

The male gorget and crown are iridescent magenta, and they are very vivid and showy.
They weigh between 2.4 and 4.5 grams and have lengths ranging from 3.5 to 4.3 inches.

The metal plate that shields the wearer’s throat during combat to prevent injuries is the inspiration behind the name of the gorget on a male hummingbird. This name is acceptable and fitting to characterize the physical characteristics of male hummingbirds, since they fight fiercely for their own territory.

The only hummingbird to reside year-round on the Pacific Coast, the Anna’s hummingbird is a native of the west coast of North America. It enjoys a Mediterranean climate with hot, dry summers and fairly wet winters.

This species is a year-round resident in much of its range, unlike many other hummingbirds that migrate.

Male Anna’s are notable for their remarkable diving displays during mating season and their ability to thrive in urbanized areas.

The male Anna’s hummingbird executes dramatic and captivating displays during courtship and diving. The entire dive display lasts 12 seconds from start to finish.
See my article: Hummingbird Dance: 5 Interpretive Explanations

Unlike many northern temperate hummingbirds, male Anna’s hummingbirds sing during courtship along with making vibrations with their tail feathers to attract a female.

Anna’s hummingbirds protect their territory with elaborate dives targeted towards predatory birds and even towards people they perceive to be threatening.
See my article: Why Hummingbirds Chase Each Other: Is it Friend or Foe?

Anna’s hummingbirds hybridize and readily crossbreed with other hummingbird species, such as the Black-chinned, Costa’s, and Rufous hummingbirds.

The oldest male Anna’s hummingbird known to exist was 8 years and 2 months old when he was captured and released during a banding expedition in Arizona.
