Where Do Hummingbirds Go in the Winter -

Why Do Hummingbirds Migrate in the Winter?

Hummingbirds migrate for two main reasons – lack of flowering plants and cold temperatures. As days shorten in late summer, blossoms begin to fade, and insect numbers decline across much of North America. This drop in critical food sources triggers a hormonal shift inside hummingbirds that initiates their southerly migrations. 

Additionally, these tiny birds would struggle to survive freezing temperatures or snowstorms. So they travel to warmer climates with more plentiful flowers and insects.

Most hummingbirds migrate astonishing distances despite their small size. For example, ruby-throated hummingbirds weighing only a few grams fly nonstop 500 miles across the Gulf of Mexico! They depend on cold fronts, bringing favourable northerly winds to complete this exhausting journey. 

By travelling to Central America, Mexico, or the Caribbean, hummingbirds escape harsh winters and gain access to the resources they need to survive.

Ruby-throated, Rufous, Allen's and Anna's Hummingbirds, Black-chinned Hummingbird, and Calliope Hummingbird

Common Hummingbird Migration Routes

Different hummingbird species follow distinct migration pathways depending on their breeding and wintering grounds. Let’s look at the migration routes and winter destinations of some widespread North American hummingbirds.

Ruby-throated Hummingbird

Ruby-throats breed across Eastern North America into Canada and then migrate south through Florida or across the Gulf of Mexico to Mexico, Central America, and Panama. Some winters as far south as Costa Rica or Venezuela. Their return trip north begins in February.

Rufous Hummingbird

This species breeds in the Pacific Northwest and Alaska, then migrates through California and the Desert Southwest to winter in Mexico. Some Rufous hummingbirds now overwinter in Gulf Coast states where feeders provide a consistent food source.

Allen’s and Anna’s Hummingbirds

While most Allen’s hummingbirds migrate south through California and Mexico, Anna’s hummingbirds are year-round residents along the Pacific Coast. Some Anna’s also overwinter in areas like Texas and Louisiana, where feeders allow them to persist farther north than otherwise possible. Both species breed in California and the Southwest.

Black-chinned Hummingbird

Black-chinneds breed across the Western United States and then migrate to Mexico for the winter months. As more people put out feeders, a few Black-chinneds attempt to overwinter along the Gulf Coast rather than migrating farther south.

Calliope Hummingbird

This smallest North American hummingbird species breeds inland through the Northwest and Rocky Mountains. They migrate south to winter in Mexico.

As you can see, winter movements vary for each species based on their breeding range and temperature tolerances. Banding studies continue to reveal more details about the migration timing and pathways followed by different hummingbirds.

What Happens to Hummingbirds That Don’t Migrate?

Most hummingbirds migrate south to escape freezing weather and scarce food in their northern breeding grounds. However, more individuals now overwinter farther north than previously recorded. What allows some hummingbirds to survive cold snaps when most migrate south?

These hardy birds enter an energy-saving state called torpor to get through frigid nights. Their metabolic rate slows up to 50 times less than normal. This torpor reduces their energy use, so stored fat provides enough warmth to survive.

By day, non-migrating hummingbirds also rely on winter-blooming flower gardens and feeders provided by people. Access to regular high-energy nectar and sugar water helps them conserve fat reserves. 

This supplemental food and their ability to minimise energy use via torpor allows some Anna’s, Rufous, Black-chinned, and other hummingbirds to endure much colder winters than in the past.

How to Help Hummingbirds in Winter

How to Help Hummingbirds in Winter

You can support wintering hummingbirds or migrants passing through your area with a few simple actions:

Leave Feeders Up

Continue filling clean feeders with fresh nectar (1 part sugar to 4 parts water) so any hummingbirds still around or migrating through have a reliable energy source. Take down empty feeders by early March so returning birds aren’t delayed by relying on feeders instead of flowers.

Provide Shelter

Hummingbirds appreciate protected perches out of the wind and cold rain where they can conserve energy. Place feeders under the eaves or porches and provide dense evergreen trees or shrubs for overnight roosting spots.

Plant Winter Flowers

Grow nectar-rich plants that bloom during winter. Good options include coral honeysuckle, red buckeye, pineapple sage, winter jasmine, and camellias. Avoid pesticides, as hummingbirds eat small insects, too.

Report Banded Birds

If you spot a hummingbird with bands on its legs, note the codes and report it to www.reportband.gov. Tracking banded birds provides valuable data on migration timing and survival rates.

With a few small actions, you can make a big difference for hummingbirds overwintering in your area or passing through on their epic migrations between summer breeding and warm wintering grounds.

Final Thoughts

During their fall and spring migrations, hummingbirds depend on networks of habitat corridors and food sources to fuel their incredible journeys. As winter approaches, most head south to warmer climates with blossoming flowers and plentiful insects. 

However, more hummingbirds now overwinter farther north than ever before, thanks to winter-blooming gardens and feeders provided by people. 

If you live in an area with winter hummingbirds, you can support these tiny travellers by providing nectar, shelter, and reporting banded birds. With our help, these aerial jewels can continue brightening even the dreariest winter days.

Frequently Asked Questions -FAQs - Hummingbirds in Winter

Frequently Asked Questions (FAQs) – Where Do Hummingbirds Go in the Winter?
