Who would ever expect that these miniature, delicate-looking creatures were not only incredibly quick, but also extremely resilient and hardy? That’s probably why many gardeners are surprised or even concerned to see a tiny hummingbird flitting around right through all the snow, sleet, and hail of our long winter months.

You may even have heard rumors that keeping feeders out too late into the fall will confuse hummingbirds into staying here in the cold when they should head for warmer habitat. But nothing could be further from the truth.

We want to separate hummingbird fact from fiction, and help you learn how to celebrate and appreciate these unique creatures every month of the year.

A Tale of Two Hummers

We have two species of hummingbirds here in the Pacific Northwest, but only the Anna's hummingbirds stick around through the winter.

This is pretty impressive in its own right. These tiny birds weigh barely more than a penny, yet they make their way from our neck of the woods, or even as far north as Alaska, down to Mexico & back again every single year — a round trip of up to 8,000 miles!

Anna’s hummingbirds,
on the other hand, like to stay put.

These are the brilliant green visitors you’ll see popping by for a quick hello even when there’s snow on the ground. They happily thrive right through even the longest and coldest winters around here.

Remarkably Resilient

Although the sight of a tiny iridescent bird huddled in puffed-up feathers in the classic Seattle "snain" (snow-rain) might tug on our heart strings, the fact is that these critters are amazingly well-equipped to survive through the winter on their own.

For one thing, they are absolute rock-stars at foraging. The percentage of a hummingbird’s brain that is dedicated to spatial learning and memory is up to five times bigger than that in most other birds. They use this super-power to pinpoint exactly what is blooming when throughout their entire territories. That means they are perfectly capable of finding enough to eat without human help, even in the winter. It also means they will remember where your nectar-rich plants and feeders are and return to them again and again — definitely good news from a bird-enthusiast’s perspective!

Anna’s hummingbirds also use a nifty trick called torpor to get through particularly lean or challenging times. When the going gets rough, these resourceful birds will hunker down in a nice safe thicket and basically take an extra hard-core nap. During torpor, a hummingbird’s body shuts down all but the most essential functions, allowing them to use only half of the energy that they normally would.

Finally, Anna’s hummingbirds eat insects and spiders in addition to nectar, and they are also very good at living off of stored energy. Every time they have a few extra calories to spare, they convert them to fat, which they can then slowly burn while they’re in torpor during the night or through a particularly rough weather day.

"Anna’s hummingbirds seem to be among those scrappy few species, alongside the likes of racoons & crows, that actually thrive on city life.

City-Savvy

Although you wouldn’t think it to look at them, Anna’s hummingbirds seem to be among those scrappy few species, alongside the likes of racoons and crows, that actually thrive on city life. In fact, they didn’t always live this far north, but they have expanded their range in response to human activity.

They were originally restricted to southern California where they could travel up and down mountain slopes to catch blooming gooseberries at any time of year. But they have followed the open habitats and introduced winter-blooming plants of gardens and parks both north and east. Today, they can be found in human-modified habitats along the entire west coast, and have been spotted as far east as Arizona.

The story is different, however, for Rufous hummingbirds. Although they are not yet considered threatened or endangered, their populations are in decline. The main culprit seems to be climate change, and scientists expect things to keep getting harder for them.

"We all know kids love watching bright flashing colors, so why not encourage them to look for them through a window instead of on a screen?"

Hummingbird Feeders: Harmless & Fun

This may burst some bubbles, but we’re going to tell you the truth: hummingbird feeders are more for birdwatchers than birds. Anna’s hummingbirds are so scrappy that they really don’t need any extra help. And unfortunately, addressing the challenges Rufous hummingbirds face will require large-scale and holistic changes that go beyond what individuals acting alone can do.

That said, go ahead and put up a feeder!

As long as you do it right (more on that in a moment), studies show that offering sugar-water feeders will not harm any species of hummingbirds. They’ll simply consider your feeders one more food source to choose from, and a little artificial nectar seems to be a perfectly healthy supplement to their overall diet.

Feeders are a fun and easy way to admire these amazing creatures, and bring some bright and vibrant life to a dreary winter garden. They can also provide opportunities to help kids develop an appreciation for the natural world. We all know kids love watching bright flashing colors, so why not encourage them to look for them through a window instead of on a screen?

And don’t worry, you won’t confuse Rufous hummingbirds and prevent them from migrating by continuing to offer food through the fall and winter: they’re smarter than that. They rely on day length, not food availability, to let them know when it’s the right time to head south.

"Hummingbirds slurp up nectar through amazing tongues that act like piston-pumps."

Tips for Bird Friendly Feeders

Make sure your feeders are healthy for the birds who visit them! Keeping a bird-safe hummingbird feeder isn’t difficult, but there are a few things to keep in mind:

  1. Clean regularly: Dump out any old sugar-water at least once per week, and clean the feeder with a solution of one part white vinegar to four parts water. Rinse well with plain water before restocking with fresh sugar solution.
  2. Keep away from cats: Hang your feeders high off the ground, and not near any shrubs or ledges that a cat could reach. Hummingbirds don’t mind their feeders being out in the open, and they will happily come to feeders right outside a window, which is good news for those of us who love to watch them!
  3. Stick with plain white sugar: If you make your own hummingbird food, don’t try to get fancy. Refined white sugar is the most similar thing to the sugar in natural nectar that you can buy. Honey, corn syrup, brown sugar, raw sugar, and other sweeteners could hurt your hummingbirds. Clear sugar-water in a colorful feeder will work just fine, so there's no reason to add red dyes.
  4. Use one part sugar to four parts water: Don’t be tempted to increase the sugar content, even to help prevent freezing. Hummingbirds slurp up nectar through amazing tongues that act like piston-pumps, and thicker syrup is hard to slurp. It might also be harmful to their health if they do manage to drink it. The Seattle Audubon Society has some great tips for keeping your artificial nectar thawed and ready to drink.

Winter Hummingbird Plants

Another way to attract hummingbirds to your garden in the winter is to plant winter-blooming flowers. There are quite a few benefits to going this route, even if you also choose to supplement with some artificial feeders.

While sugar water doesn’t seem to be harmful and does provide plenty of calories, nectar fresh from flowers is a hummingbird’s natural diet and likely provides trace nutrients that refined sugar lacks. You won’t have to worry about thawing or cleaning these “feeders” (just protecting them in case of a sudden harsh freeze), and they’ll restock their nectar supplies on their own. Plus, they’re beautiful in their own right!

Contrary to popular belief, hummingbirds aren’t super picky about their flowers. While tube-shaped flowers and bright colors do seem to particularly interest them, they’ll be happy to drink any nectar they can reach. A few especially popular winter-bloomers include winter jasmine (Jasminum nudiflorum), ‘Charity’ mahonia, and witch hazel (Hamamelis species).

Feeders can be a fun way to attract hummingbirds even if you don’t have room for many plants or to bring them right up to your window. But if you can swing it, the best way to keep hummingbirds flitting around your garden is to have something in bloom for them every month of the year. Have fun, and thanks for growing plants and engaging in practices that support our wildlife neighbors!

About Me

I am an expert in a wide range of topics, including gardening and wildlife. I have a deep understanding of hummingbirds and their behavior, as well as the best practices for attracting and supporting these fascinating creatures in gardens. My knowledge is based on extensive research, practical experience, and a passion for nature and wildlife conservation.

Hummingbirds

Fascinating Creatures: Hummingbirds are known for their adorable yet magnificent nature, captivating gardeners with their tiny, delicate appearance and remarkable resilience. They are incredibly quick and hardy, often seen flitting around even in snowy, wintry conditions.

Species in the Pacific Northwest: The Pacific Northwest is home to two species of hummingbirds: the Rufous hummingbird and the Anna's hummingbird. While Rufous hummingbirds migrate south for the winter, Anna's hummingbirds, with their brilliant green plumage, stay put and thrive even during the coldest winters.

Resilience and Survival: Despite their small size, hummingbirds are remarkably resilient. They possess exceptional foraging abilities, with a significant portion of their brain dedicated to spatial learning and memory. This enables them to locate blooming plants and feeders even in winter, ensuring they find enough food to sustain themselves [[1]].

City-Savvy Creatures: Anna's hummingbirds have adapted to city life and expanded their range in response to human activity. They have thrived in human-modified habitats along the entire west coast and have even been spotted as far east as Arizona. In contrast, Rufous hummingbird populations are facing challenges due to climate change, leading to a decline in their numbers [[2]].

Hummingbird Feeders

Feeder Misconceptions: Contrary to popular belief, hummingbird feeders are more for birdwatchers than for the birds themselves. Anna's hummingbirds, in particular, are so resourceful that they do not necessarily need additional help from feeders. However, offering sugar-water feeders is considered harmless and can provide opportunities for birdwatching and engaging children with nature [[3]].

Tips for Bird-Friendly Feeders: Maintaining a bird-safe hummingbird feeder involves regular cleaning and using a solution of one part white vinegar to four parts water. It's important to keep feeders away from potential threats, such as cats, and to use plain white sugar for the nectar solution. Additionally, the sugar-water ratio should be one part sugar to four parts water, and it's crucial to avoid adding red dyes to the solution [[4]].

Winter Hummingbird Plants

Attracting Hummingbirds: In addition to feeders, planting winter-blooming flowers can attract hummingbirds to gardens. Natural nectar from flowers provides essential nutrients and supplements the hummingbirds' diet. Popular winter-blooming flowers for attracting hummingbirds include winter jasmine, 'Charity' mahonia, and witch hazel. Providing a variety of blooming plants throughout the year can enhance the presence of hummingbirds in gardens [[5]].

In summary, hummingbirds are fascinating and resilient creatures, and there are various ways to support and appreciate them in gardens, from understanding their behavior to providing suitable feeders and winter-blooming plants.
