Like many other bird species, hummingbirds migrate south in the fall to find food sources like flowers and insects. This journey isn’t triggered by hunger or cold temperatures, but by decreasing daylight hours. The drop in daylight tells them it’s time to head for warmer places.
In late winter and early spring, they return north to breed in the United States and Canada. This northward migration helps them avoid the intense competition for food in the tropics. In the North, they get a prime spot at the table, where summer food is plentiful.
Once they arrive in the United States, Ruby-throated Hummingbirds can travel up to 20 miles daily, typically following their favorite early-blooming flowers. Despite a common myth, hummingbirds don’t hitch rides on geese or other birds. However, they sometimes travel in mixed flocks over water. This way, they protect each other from possible dangers in the air.
2. Ruby-throated Hummingbird: A Detailed Look at Migration
Where do Ruby-throated Hummingbirds go during the winter? Ruby-throated Hummingbirds migrate to southern Mexico and Central America for the winter. In spring, Ruby-throated Hummingbirds fly north into the U.S. and southern Canada to breed during the summer.

The return journey can start as early as mid-July for some adults, but most wait until late August or early September. Most are headed for southern Mexico and Central America, but some stay in the southern United States along the Atlantic and Gulf Coasts. Those that stay in the U.S. are usually migrants from Canada that have already traveled thousands of miles.
Ruby-throated Hummingbird populations are growing, thanks to backyard feeders and their ability to live in open and forest-edge habitats. The International Union for Conservation of Nature (IUCN) lists this bird as a species of Least Concern, meaning its population is stable. According to the U.S. Fish and Wildlife Service, protecting their habitats and food sources is essential to maintaining their healthy population numbers.
3. Rufous Hummingbird: An Epic Journey
How far does the Rufous Hummingbird migrate? The Rufous Hummingbird migrates approximately 3,900 miles each way, making it one of the longest migrations for a bird of its size. For a bird its size, the three-inch-long Rufous Hummingbird makes one of the longest migratory trips in the bird world. Its 3,900-mile journey is roughly equal to 78.4 million body lengths.

The Arctic Tern’s one-way journey of 11,000 miles, by comparison, is less than 52 million body lengths. The Rufous Hummingbird’s migration route forms a clockwise loop: The birds leave their Mexican wintering grounds in early spring, arriving in Washington State and Canada by May, via a long flight up the Pacific Coast.
After a short stay in the North—some birds begin heading back as early as July—they travel south through the Rocky Mountains. Rufous Hummingbird populations are declining due to habitat loss, and the IUCN lists this bird as Near Threatened. Habitat preservation efforts are crucial to helping this species survive, according to studies from the National Audubon Society.
4. Black-chinned Hummingbird: Adaptable Migrants
Where do Black-chinned Hummingbirds spend the winter? Black-chinned Hummingbirds spend the winter in western Mexico and along the Gulf Coast. During the summer, Black-chinned Hummingbirds live in a large part of the western United States. They are one of the most adaptable hummingbirds in the U.S., living in many habitats, including urban areas.

After breeding, many adult birds move to higher elevations to feed on mountain flowers before heading south in the fall. Most travel to western Mexico, though some spend the winter along the Gulf Coast. Black-chinned Hummingbird populations are increasing, likely because of backyard hummingbird feeders and their ability to live in various habitats. The IUCN lists the Black-chinned Hummingbird as a species of Least Concern, indicating a stable population.
5. Allen’s Hummingbird: Early Departures and Unique Destinations
When do Allen’s Hummingbirds begin their migration? Allen’s Hummingbirds start their migration as early as December. Compared to other North America-bound migrants, Allen’s Hummingbirds get an early start. Those that migrate leave their wintering grounds in early December, allowing them to arrive along the coasts of California and Oregon in January. This timing lets them enjoy the region’s winter wildflowers.
Allen
During the breeding season, female and male Allen’s Hummingbirds live in different habitats: Males claim territories in coastal shrub areas, while females move into forests to build nests. There are two subspecies of Allen’s Hummingbird, each with its own winter destination. One group (Selasphorus sasin sasin) migrates to central Mexico. The other (S. s. sedentarius) stays in southern California.
Though Allen’s Hummingbird is still fairly common, its numbers have dropped by 83 percent in recent decades, according to Partners in Flight. If trends continue, Partners in Flight estimates that the bird’s current population could be cut in half in less than 20 years. Conservation efforts are essential to reverse this decline, as noted by the California Department of Fish and Wildlife.
6. Anna’s Hummingbird: The Non-Migratory Exception
Which hummingbird species does not migrate? Anna’s Hummingbird is a non-migratory species, residing along the Pacific Coast throughout the year. Unlike most North American hummingbirds, Anna’s Hummingbirds don’t migrate, though they may move short distances to find more food.
Anna
Anna’s Hummingbirds now live in an area from northern Mexico to Southern Canada, but this wasn’t always the case. In the early 20th century, their breeding range was much smaller, limited to Baja, Mexico, and southern California. This changed with the introduction of exotic flowering trees along the West Coast, which offered more nectar and nesting spots.
Anna’s Hummingbird populations are also growing thanks to backyard hummingbird feeders. The IUCN lists this bird as a species of Least Concern, indicating a healthy population. According to the Seattle Audubon Society, the adaptability of Anna’s Hummingbird has allowed it to thrive in urban environments.
7. Factors Influencing Hummingbird Migration Patterns
What factors influence hummingbird migration? Several factors influence hummingbird migration patterns, including food availability, climate, and daylight hours. Hummingbird migration is a complex behavior influenced by a variety of environmental and biological factors. Understanding these factors can provide insights into why hummingbirds migrate and how they adapt to changing conditions.
Food Availability:
- Nectar Sources: The availability of nectar from flowers is a primary driver of hummingbird migration. Hummingbirds follow the blooming patterns of flowers, moving to areas where nectar is abundant. In the spring and summer, they migrate north to take advantage of the flowering plants in North America. As these plants die off in the fall, they migrate south to regions where flowers continue to bloom year-round.
- Insect Abundance: Insects are another essential food source for hummingbirds, particularly during the breeding season when they need protein to feed their young. The availability of insects also influences their migration patterns, as they move to areas where insect populations are high.
Climate:
- Temperature: Hummingbirds are sensitive to temperature changes. They migrate to avoid freezing temperatures, which can be fatal to these small birds. The onset of cold weather in the fall triggers their southward migration, while the warming temperatures in the spring signal it’s time to return north.
- Rainfall: Rainfall patterns can also affect hummingbird migration. Adequate rainfall is necessary for flower growth and insect abundance, so hummingbirds tend to migrate to areas with sufficient rainfall.
Daylight Hours:
- Photoperiod: The length of daylight hours, known as the photoperiod, plays a crucial role in regulating hummingbird migration. As daylight hours decrease in the fall, it triggers hormonal changes in hummingbirds that prepare them for migration. These changes include increased fat storage and migratory restlessness.
- Biological Clock: Hummingbirds have an internal biological clock that helps them track the changing seasons. This clock is synchronized with the photoperiod, allowing them to anticipate the best time to migrate.
Habitat and Geography:
- Habitat Availability: The availability of suitable habitat along migration routes is essential for hummingbirds. They need stopover sites where they can rest and refuel. The loss of habitat due to deforestation and urbanization can disrupt their migration patterns.
- Geographic Barriers: Geographic features such as mountain ranges and bodies of water can influence hummingbird migration routes. Hummingbirds tend to follow corridors that provide the easiest passage and access to food and shelter.
Competition and Predation:
- Competition: Competition for resources, such as nectar and nesting sites, can influence hummingbird migration. They may migrate to areas where competition is less intense.
- Predation: The risk of predation can also affect hummingbird migration. They may avoid areas with high predator populations or migrate at times when predators are less active.
Genetic Factors:
- Inherited Traits: Migration patterns are partly determined by genetics. Hummingbirds inherit migratory tendencies from their parents.
- Adaptation: Over time, hummingbird populations adapt to specific migration routes and timing through natural selection.
Understanding these factors helps scientists and conservationists protect hummingbird populations. By preserving habitats, managing resources, and mitigating threats, we can ensure these tiny travelers continue to thrive.

This loss of habitat reduces the availability of food and shelter, making it more difficult for hummingbirds to survive.
- Shift in Vegetation Zones: Climate change is causing shifts in vegetation zones, which can alter the distribution of plants that hummingbirds rely on for nectar. As vegetation zones move, hummingbirds may have to travel farther to find suitable food sources.
Changes in Migration Timing and Routes:
- Earlier Migration: Some studies suggest that hummingbirds are starting their spring migration earlier in response to warmer temperatures. However, this can lead to mismatches with the availability of food sources if plants do not bloom early enough to coincide with their arrival.
- Altered Migration Routes: Climate change may force hummingbirds to alter their migration routes in search of more suitable conditions. This can lead to increased energy expenditure and higher mortality rates.
Increased Exposure to Extreme Weather Events:
- Heat Waves: Extreme heat waves can be particularly harmful to hummingbirds, as they can cause dehydration and heat stress.
- Severe Storms: Severe storms and hurricanes can disrupt migration patterns, damage habitats, and increase mortality rates.
Impact on Breeding Success:
- Mismatched Timing: Climate change can disrupt the timing of hummingbird breeding cycles, leading to mismatches between when they nest and when food is most abundant. This can reduce breeding success and lower population numbers.
