While fairies are mythical, hummingbirds are real-life winged fairies of our gardens. We tend to think of just bees and butterflies as pollinators, but the tiny, jewel-like birds also play a crucial pollinator role. Hummingbirds co-evolved with native nectar plants, each benefiting the other. A keystone species (a species which other species in an ecosystem largely depend on, so if it disappeared the ecosystem would be severely altered), hummingbirds pollinate at least 20% of specialized indigenous plant species.
Hummingbird Facts
Hummingbirds have a very high metabolism and must eat all day. They consume about half their body weight each day while feeding. Nectar from 1,000-2,000 flowers provides 20% of a hummingbird's daily diet, which they drink with a fringed forked tongue in their long beak. Insects provide the bulk of their diet, which includes beetles, aphids, gnats, mosquitoes and wasps.
The smallest hummingbird, the Bee hummingbird (Mellisuga helenae), is a native of Cuba. With a body about an inch long, it weighs the equivalent of 1/4th teaspoon of sugar! The “large” Giant hummingbird (Patagonia gigas) of western South America is about eight inches long (20 cm), weighing less than half of most sparrows.
California Hummingbirds
California has about nine species of hummingbirds with four commonly seen species in the Stanislaus County area listed here in order of most abundant to the least:
- Anna's hummingbird (Calypte anna): This permanent year-round resident is a common sight in many of our gardens. The colorful red-headed male is the largest and most prominent of our local hummingbirds. The fastest of all hummingbirds, it can fly up to 60 miles per hour. Males perform a death-defying courtship dive, plummeting to the ground at speeds and accelerations that put jet pilots to shame. Females build the nests and care for the young alone, having three broods a year.
- Rufous hummingbird (Selasphorus rufus): With its beautiful orange-red gorget (a hummingbird's brilliant throat feathers), these migrating birds are a beautiful sight in local gardens in the spring and fall. Unlike the green body feathers of other common species in our area, the male has copper-colored feathers. Nesting further north than any other hummingbird, they fly up to 2,000 miles (3,200 km) during their migratory journeys to Canada.
- Black-chinned hummingbird (Archilochus alexandri): Another migratory species, it spends winters in Central America while nesting here in the summers. The male has a black face with a purple gorget at the base of the chin. The female builds a well-camouflaged nest in a shrub or tree.
- Costa's hummingbird (Calypte costae): The smallest and least common of our local hummingbirds, it breeds and nests here in summers, spending winters in Baja California/western Mexico area. The male has a colorful purple gorget and neck.
A Hummingbird Friendly Garden
To make the sugar syrup combine one-part white cane sugar to four parts boiling water and let cool. Do not use honey, molasses, brown sugar, agave, artificial sugar, etc. as these can be harmful to hummingbirds. Food coloring is unnecessary since the red color of the feeder will attract the birds. If possible, place the feeders out of direct sunlight. Refill and clean feeders every 3-4 days (more frequently in hot weather) with a bottle brush, hot water, and a little white vinegar (which retards mold). Extra sugar syrup can be stored in refrigerator for a week or so.
In addition to sucrose, nectar provides additional sugars (glucose and fructose), along with compounds such as carbohydrates, amino acids, vitamins and oils which sugar feeders cannot provide. So, flowering plants that produce nectar should also be present in your garden to give hummingbirds a diverse, nutritious diet. Hummingbirds favor flowers that are tubular, in red, orange or bright pink colors. Some good choices include penstemons, fuchsias, red salvias, and bee balms.
A hummingbird friendly garden should also include trees and bushes for perching, hiding and nesting, water for drinking and bathing, and safety from domestic cats.
An excellent plant list resource provided by UC Agriculture & Natural Resources (UC ANR) and Master Gardener is Plants that Attract Hummingbirds – Zones 8 and 9: https://ucanr.edu/sites/UC_Master_Gardeners/files/287098.pdf
Hummingbird Challenges
Both the local Rufous hummingbirds and Black-chinned hummingbirds are among those considered to be at risk (https://www.audubon.org/news/how-climate-change-threatens-hummingbirds).
By providing backyard sanctuaries with feeders and native plants we can help support these valuable feathered fairies of our gardens, so they can continue to delight us and pollinate our plants.

There are three groups of plants that attract birds and each group draws different types of birds: Nectar plants, plants that provide seeds or nuts, and plants that produce berries or fruit. Many plants will provide more than one source of food, i.e., nectar in the spring and berries in autumn.
Here is a list of a few favorite native plants in each group and some of the birds they may attract.
Hummingbirds and Nectar
Hummingbirds prefer tubular shaped flowers that fit the length of their beak, and are bright in color, particularly red. Native salvias (sages), penstemon, columbine, and honeysuckle all serve up nectar for hummingbirds.
- Sages (Salvias): There are about 18 sages native to California, with Hummingbird sage (Salvia spathacea) being one of them. The common name says it all! Fruity scented dark rose-lilac blossoms appear in March – May. It also produces autumn seeds that attract birds such as sparrows and finches.
- Western Redbud (Cercis occidentalis). A small deciduous tree or shrub found in the foothills and mountains of California with distinctive shiny heart-shaped leaves. The showy bright pink or magenta flowers develop in the later winter and spring, growing in clusters all over the shrub, making the plant very colorful and noticeable in the landscape. Goldfinches and sparrows will feed on seeds produced in the fall.
- California Fuchsia (Epilobium canum). There's probably no better California native plant for attracting hummingbirds. A perennial plant, it blooms a bright profusion of scarlet flowers in spring and summer, and is often the only native California flowering plant blooming at the height of summer.
Birds That Eat Seeds
- Bush sunflower (Encelia californica), commonly referred to as "California bush sunflower.” With abundant bright yellow daises, it is beautiful in late winter through summer. Attracts goldfinches, sparrows, orioles, crows, Scrub jays, grosbeaks.
- California aster (Symphyotrichum chilense). A member of the Asteraceae family it is native to western North America. The summer blooming flowers come in blues, purples and yellow colors. It is also a host plant for the Northern Checkerspot, Field Crescent and Pearl Crescent butterflies.
- Deergrass (Muhlenbergia rigens), also known as Meadow Muhly and Deer Muhly, is a summer-growing, perennial bunchgrass whose seeds attracts woodpeckers, finches, grosbeaks, crows and jays.
Berry Plants are Important to Birds
Many shrubs and small trees provide berries that ripen at different times, so providing a seasonal variety, such as cherries for birds during the breeding seasons of spring and summer, and holly in winter, helps sustain birds throughout the year.
- Golden Currant (Ribes aureum). A deciduous plant that blooms in late winter and spring with golden yellow flowers that attract hummingbirds. The ripe berries in autumn are amber yellow to black in color, are edible, and attract a wide range of birds. There are two main varieties: Ribes aureum var. aureum and Ribes var. gracillimum.
- Blue Elderberry (Sambucus Mexicana). Also known as Mexican elderberry, the berries from elderberries are one of the most important sources of food for birds in California. Native from Oregon to Baja all the way to western Texas, it has cream or yellow flowers in the spring and purple berries in the fall.
- Toyon (Heteromeles arbutifolia). Toyon is a beautiful perennial chapparal shrub native throughout the western part of California and the Sierra foothills. It is also known by the common names Christmas berry and California holly from the bright red berries it produces during the winter months, which are produced in large quantities, maturing in the fall and persisting well into the winter. Note: the berries are toxic to humans in large amounts.
- California False Buckthorn (Frangula californica). This perennial, evergreen shrub is also known as Coffeeberry due to its berries containing seeds that resemble coffee beans. The shrub produces small, greenish white flowers in the summer, followed by dark berries that are sought after by birds.
By providing a variety of native plants that produce nectar, seeds and berries to attract different types of birds, you'll be providing a healthy haven for birds all year round, along with many other species of pollinators such as bees and butterflies!

In our previous blog, we posted a Pollinator Quiz. How did you do? Check the answers below to find out. Please post your responses in the comments section, or reply to the post on our Facebook page.
Question #1: What is pollination?
Pollination happens when pollen is moved by an insect, animal, or the wind. Pollen moves between the male part of a flower to the female part of either the same flower or another flower of the same species. This is how fertilization takes place and produces fruits and seeds.
Question #2: Which of the following are pollinators?
- (European) Honey bees
- Flies
- Wasps
- Butterflies
- Moths
- Hummingbirds
- Dragonflies
- Rats
- Native bees
- Lizards
- Beetles
All the above are pollinators, except for dragonflies, rats, and lizards! You may have been surprised to see flies, wasps, bats, and beetles listed. These pollinators help fertilize plants, although some are more efficient than others. You can support these animals and insects by planting a pollinator garden.
Question #3: What 3 important things do you need to provide in your garden to support pollinators?
When planning a pollinator garden, keep these 3 elements in mind:
Food
Flowers provide nectar (energy) and pollen (protein) for pollinators. However, moth and butterfly larvae (also called caterpillars) often rely on one specific plant for food.
To attract pollinators when planning your garden, purchase at least three of each kind of plant species and plant them in a group. This makes it easier for pollinators to find the plants and to return to your garden.
In fall and late winter, nectar and pollen resources are scarce, so look for plants such as Knifophia ‘Christmas Cheer,' California fuchsia (Epilobium spp.), various species of salvia such as ‘Mexican Sage' (Salvia leucantha) and Gooseberry (Ribes spp.). You can also visit nurseries and garden centers to see what's in bloom during those times.
Water
Many pollinators need water for survival. Bird baths and fountains attract hummingbirds and bees and help them stay hydrated. However, make sure your water source isn't too deep, or the pollinators may drown. Add pebbles or stones to shallow dishes and floating corks to deeper containers.
Shelter
Moths and Butterflies
In addition to providing food for moths and butterflies, larval food plants also provide shelter. If you remember the book The Very Hungry Caterpillar, these critters eat a lot! Make sure you have enough food, and be prepared to have your plants stripped bare of leaves if you get a lot of caterpillar visitors!
Native Bees
Seventy percent of native bees nest in the ground, so leave bare areas in your landscape for them. The other thirty percent nest in wood or a cavity created by another critter. Create bee boxes by drilling holes ¾ apart of various diameters between ¼ to ⅜ inches. To see native bee photos, visit the UC Davis Arboretum & Public Garden page Beyond the Honey Bee. To create habitat for wood nesting bees, visit this Xerces Society page for directions.
Honey Bees
If you want to have your own hive, you can learn all about it and even take classes at UC Davis. Visit the Apiculture Courses page.
