Hummingbird Migration in Missouri

When Do Hummingbirds Arrive in Missouri?

Missouri’s earliest migrating hummingbirds begin arriving in late March and continue north to their preferred nesting area, somewhere near their own birth.
The last of the spring migrating Missouri hummingbirds are gone by mid-June, however, many will stay in Missouri for the rest of the summer.

The height of migration activity in Missouri occurs in the months of April and May according to the Missouri Department of Conservation.

Missouri migrating hummingbirds, including the most common Missouri hummingbird, the Ruby-throated hummingbird, continue their way north into Canada; eastward into all states to the Atlantic Ocean.

Beginning their northern journey from as far away as Panama or as close as Mexico, migrating hummingbirds begin to arrive in Missouri in late March, some late migrators may arrive as late as late-May, but by the end of June, all hummingbirds that are migrating further than Missouri are gone from Missouri.

The first migrating hummingbirds will be males followed by the females about a week later. The males arrive first to stake out the territory that they will defend as they try to attract a female.

Keep your eye out for the brightly colored gorget of the male, the females will start showing up at your feeders about a week later.

Hummingbirds starting their spring migration from Panama need to fly about 2,150 miles to reach Missouri.

Hummingbirds starting their journey from Mexico need to fly about 1,075 miles to reach Missouri.

What Hummingbirds Breed and Nest in Missouri?

The Ruby-throated hummingbird is the only hummingbird that breeds and nests in Missouri.
Most Ruby-throated hummingbirds will raise two broods in Missouri but some of the early arriving or late leaving Ruby-throated hummingbirds will have enough time to raise a third brood in the same year.

The entire reason for northern migration, much like salmon swimming upstream to their place of birth to lay eggs, is to return to the area where they were born to mate, build a nest, and raise a family.

Once the breeding grounds have been reached, the focus turns to finding a partner with which to mate.

Each species of male hummingbirds has its own unique mating dance ritual of courtship to attract a female. They do perfectly choreographed dives and dance maneuvers to attract a flirty female.
See my article: Hummingbird Dance: 5 Interpretive Explanations

There is no penetration during the mating ritual as male hummingbirds do not have any external sexual organs.

The hummingbird mating process only lasts for approximately 3-5 seconds while the cloacae (kloh-ay-see) of both hummingbirds are pressed together in what is called the “Cloacal Kiss” (kloh-a-coal kiss).

After the Cloacal kiss, the female must begin building the nest immediately.

Female hummingbirds prefer building nests 10 to 20 feet off the ground in deciduous trees.

It will take her between 5 and 7 days to construct the nest of materials such as plant down, moss, and fine plant fibers, decorated with lichens and held together by spider webs.

See my article: Baby Hummingbirds: (Egg to Fledgling)

Hummingbirds usually lay 2 eggs per brood, one each on consecutive days.

Most hummingbirds have 2 broods per year, but depending on migration time and day length in their nesting destinations, some hummingbirds can have more than 2 broods per year.

In Missouri, nesting hummingbirds usually have 2 broods per year but some may have time to work in a third brood.

When Should I Put Out Hummingbird Feeders in  Missouri?

Missouri hummingbird enthusiasts should put out hummingbird feeders at the end of February to attract the earliest arriving migrating hummingbirds.
Male hummingbirds will be the first to arrive followed by female hummingbirds about a week later.

Putting hummingbird feeders up in late February in Missouri may encounter freezing temperatures.

Migrating hummingbirds will continue to arrive in Missouri until about mid-June.
Hummingbirds seen in Missouri after mid-June will be hummingbirds that will spend their entire summer in Missouri.

Be sure to fill your hummingbird feeders with good quality nectar solutions, making your own feeder nectar is best.

How Long Do Hummingbirds Stay in  Missouri?

Missouri’s migrating hummingbirds will start arriving in late February and most will be gone by the end of October.
Missouri has no hummingbirds designated as year-round residents.
Some Ruby-throated hummingbirds that usually migrate may choose to over-winter in Missouri, but most will migrate south for the winter.

Ruby-throated and Rufous hummingbirds are the most adapted hummingbirds to cold temperatures.

Hummingbirds are much more tolerant of cold temperatures than most people realize.

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

See my article: 11 DIY Ways to Keep Hummingbird Nectar From Freezing

Ruby-throated hummingbirds, or some hummingbirds too old or injured to migrate, will be the only likely hummingbirds Missourian hummingbird enthusiasts will see during the winter.

The second most likely migrating hummingbird that might choose to spend the winter in Missouri would be a Rufous hummingbird, although there have only been very limited sightings of Rufous hummingbirds in Missouri.

Hummingbirds have exceptional memories and will remember every flower or feeder they visited on the spring migration and will return to those nectar sources on their return to southern migration in the fall.

The most common hummingbirds Missourians will see during the hot summer months will be the Ruby-throated hummingbird with the Rufous hummingbird being a very distant second.

When the obstacles of the Missouri summer heat are difficult to manage and unbearable, finding ways to keep your hummingbirds happy and hydrated with cool nectar can be critical.

When Do Hummingbirds Leave Missouri?

Missouri’s migrating hummingbirds begin leaving the state in mid-August, migrating south to their over-wintering areas in Mexico and Central America.
Missouri migrating hummingbirds will all be gone by mid-November.

This information is collaborated in two separate publications by the Missouri Department of Conservation (MDC).

The MDC states Missouri hummingbirds start their fall migration south in mid-August.

The MDC, in a separate publication, recommends leaving hummingbird feeders up in Missouri until after Thanksgiving.

This elongated migration time frame ensures late straggling migrants have enough food available to fuel their bodies before making the long taxing migration south for the winter.

Hummingbirds Missourians might see during the winter are possibly some migrating hummingbirds that are too old or injured to migrate.

Hummingbird migration is triggered by the circadian (internal daily clock) and the circannual (yearly internal clock) rhythm.

Changes in the weather, temperature, time of the season, the decline in the food supply, and decreased amount of sunlight because of shortening days are all factors that trigger an individual hummingbird’s instinct to migrate.

As with spring migration, male hummingbirds are the first to begin the southern migration in the fall. The female migrating hummingbirds will begin their southern fall migration as soon as they have completed raising their offspring to the ability to migrate themselves.

How Long Does It Take a Missouri Hummingbird to Migrate?

It takes a Missouri hummingbird about 36 hours of flying at its average migrating flight speed of 30mph to fly from Missouri to the most distant Mexican border 1,075 miles away.
Hummingbirds migrating to Panama, 2,150 miles away, will need to fly 72 hours.

Some fly at the relaxed distance as slow as 1 hour per day, others fly up to 500 miles non-stop in about 20 hours, as some do while migrating across the Gulf of Mexico.

Hummingbirds do not migrate in flocks as do other migrating birds.
Hummingbirds migrate individually on their own personal time clock.

This staggered migration pattern ensures resources are not consumed and depleted all at one time.

As migration approaches, hummingbirds routinely gain 25% to 50% of their body weight by consuming increased quantities of nectar from feeders and flowering plants as well as catching an increased quantity of bugs mid-air for protein.

This increase in body fat helps fuel the hummingbird on its long migration journey.

Expect to see an increased volume of southern migrating hummingbird visitors to your feeders in Missouri during this fall migration from September through October.

The hummingbirds that visited your feeders during the spring migration will remember exactly where your feeder is located and will most likely revisit that same feeder on their way to their over-wintering area in Mexico and Central America.

When To Take Down Hummingbird Feeders in Missouri?

The best time to take down hummingbird feeders for the winter in Missouri is mid-to-late November or when no hummingbirds have been seen at the feeders for a couple of weeks.
Many Missourians leave feeders up all winter to feed over-wintering hummingbirds and those too old or injured to migrate.

The dilemma hummingbird enthusiast struggles with every year is whether to leave the hummingbird feeders up all year or take them down during the winter.

Some Missouri hummingbird admirers leave hummingbird feeders up all winter long to provide life-nourishing nectar to Missouri’s only likely over-wintering residents, the Ruby-throated and Rufous hummingbirds, as well as some seasonal hummingbirds that choose to stay in Missouri for the winter.

Most hummingbirds will not spend the winter in Missouri and will decide to migrate south for the winter.

The selfless act of keeping hummingbird feeders up all winter also provides nectar to other migrating species unable to migrate because of injury or old age.

See my article: Should I Keep My Hummingbird Feeder Out During the Winter?

Hummingbird enthusiasts that leave hummingbird feeders up all winter provide much-welcomed nutrition for year-round, migrating, and hummingbirds too old or injured to migrate.

According to, some hummingbirds have been documented surviving -9 degrees Fahrenheit with a wind chill factor of -36 degrees Fahrenheit.

Taking hummingbird feeders down mid-winter could be fatal to hummingbirds depending on these winter-time feeders.

Where Do Missouri Hummingbirds Go in The Winter?

Missouri migrating hummingbirds travel south to over-winter in Mexico, Guatemala, Belize, Honduras, El Salvador, Nicaragua, Costa Rica, and Panama.
During a mild winter, some Missourians may see a hummingbird at their feeder, most likely a Ruby-throated or Rufous hummingbird.

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

All hummingbirds have excellent memories and can remember every flower or feeder they visited during spring migration and will return to those locations along their migration pathway year after year.

Some hummingbirds have been documented returning to a feeder for a couple of years after it was removed.
