Feeding Birds in California
A Mediterranean climate flips the standard North American feeding calendar. Your busiest months are the wet ones, and for half the year a dripping bird bath will bring in more species than any feeder you own.
The short answer
- Keep a hummingbird feeder up all twelve months. Anna's hummingbird is a year-round resident across most of lowland California and does not migrate away in winter.
- From roughly May to October, water is the strongest attractant in the yard. A shallow bath with moving water beats any seed you can buy.
- The feeder peak is fall through early spring, when white-crowned sparrows, juncos and larger goldfinch flocks arrive and natural seed runs short.
- Summer heat spoils nectar in a day and turns sunflower rancid in weeks. Buy small, store cool, refill less.
- This guide covers cismontane lowland California. The high Sierra, the far north coast and the southeastern deserts each behave like a different region.
California is not one feeding region. A feeder in San Diego, one in Sacramento, and one in a Sierra town at 6,000 feet (1,800 m) get different birds on different schedules, and advice written for one is often wrong for the others.
What ties the lowland and coastal parts of the state together is a wet-winter, dry-summer pattern that reverses the usual North American feeding calendar. The busy months are fall through spring. Midsummer is quiet at the seed feeder and frantic at the water.
Two things follow that most guides get wrong here. Hummingbird feeders stay up all twelve months, because Anna's hummingbird does not leave. And from May to October, water does more for your yard list than seed does.
Where this guide applies#
This page is about cismontane California: the coast, the coast ranges, the Central Valley and the southern lowlands, roughly everything west of the Sierra crest and below about 4,000 feet (1,200 m). Boundaries like these are approximations, and a yard near an edge will show features of both sides.
- Sierra Nevada and Cascade elevations above roughly 5,000 feet (1,500 m) behave like the Mountain West: mountain chickadees, bear rules, a short hummingbird season.
- The far north coast and Klamath country grade into the Pacific Northwest, wetter and cooler year-round.
- The Mojave, Colorado Desert and Imperial Valley belong with the Southwest, where heat management and water are the whole game.
Birds at a California feeder#
The state's signature feeder birds are not the ones on the packaging of most seed bags. Oak woodland and chaparral species dominate, and several of them are found almost nowhere else in the country.
| Bird | What brings it in | When |
|---|---|---|
| California scrub-jay | Whole peanuts, sunflower | Year-round |
| Lesser goldfinch | Nyjer, sunflower chips | Year-round, bigger flocks fall to spring |
| House finch | Black oil sunflower | Year-round, often the most abundant bird |
| Anna's hummingbird | Nectar, 1 part sugar to 4 water | All twelve months |
| Rufous hummingbird | Nectar | Migration windows, late winter to spring and again in fall |
| American goldfinch | Nyjer, sunflower hearts | Mostly fall through spring in the lowlands |
| Oak titmouse | Sunflower, suet, peanut bits | Year-round in oak country |
| Bushtit | Suet, no-melt dough | Roving flocks, heaviest fall and winter |
| White-crowned sparrow | White millet on the ground | Roughly October into April |
| Dark-eyed junco | Millet, small seed on a low tray | Year-round in the coast ranges, widespread in winter |
| Spotted towhee | Millet and sunflower under cover | Year-round |
| Northern flicker | Suet | Fall through spring |
| Steller's jay | Peanuts, sunflower | Foothills, conifers and mountain towns |
Add mourning doves almost anywhere there is ground seed, and cedar waxwings in winter flocks that ignore feeders entirely and strip your toyon and pyracantha instead.
Anna's hummingbird changes the rules#
Most of the country puts hummingbird feeders out in spring and takes them down in fall. California does not. Anna's holds territory through the winter, feeds on nectar in January, and has expanded its range substantially over the last century, helped along by garden plantings and by feeders.
That makes your feeder a year-round commitment, not a seasonal one. Use the plain sugar and water recipe, one part white sugar to four parts water, and nothing else. No red dye, no honey, no substitutes.
The winter risk is freezing, not starvation. In interior valleys and the foothills, nectar can ice up on a cold night. Bring the feeder in after dark and hang it out again at dawn, or keep two feeders and swap them. The taking down hummingbird feeders guidance about waiting two weeks past the last bird applies to migrants elsewhere, not to resident Anna's.
Nectar spoils fast in California summers
At 90°F (32°C) and above, sugar water ferments and grows mold within about 24 hours. Change it daily in hot weather and every two to three days in mild coastal conditions, and scrub the ports rather than just rinsing. The method is in cleaning a hummingbird feeder.
Water beats seed for half the year#
From about May through October, much of California gets almost no rain. Natural water sources shrink to nothing, and a reliable, shallow, moving water source becomes the single most productive thing in the yard. Warblers, vireos, tanagers, waxwings and bushtits will come to water when they would never touch a feeder.
Keep it shallow, no deeper than 2 inches (5 cm), with a rough surface for grip. Add movement: a dripper or a small mister costs little water and multiplies the draw, because the sound carries. The details are in drippers, misters and moving water.
During drought, water is the feeder
If you can only maintain one thing well in a California summer, maintain the bath. Scrub it every two to three days with a stiff brush, because warm shallow water grows algae and concentrates birds in a way that can spread disease. A clean bath is an asset, a slimy one is a liability.
A California feeding calendar#
Seasons here run wet and dry rather than warm and cold, and the feeder year follows the rain.
- September to November. The main buildup. White-crowned sparrows and wintering juncos arrive over a window from late September into October. Start refilling more often, add a ground tray, and check fall feeding for the transition.
- December to February. Peak feeder traffic. Sunflower, nyjer and suet all get used hard. Anna's hummingbirds are on territory and often nesting by late winter, which is genuinely early by national standards.
- March to May. Sparrows and juncos thin out and leave over several weeks. Rufous and Allen's hummingbirds pass through. Feeder traffic drops as insects become abundant.
- June to August. The quiet stretch. Adults bring fledglings through for a few weeks, then most families disperse. Cut seed volume, keep nectar and water going hard. See summer feeding for the reasons a quiet feeder is normal.
Heat, spoilage and buying less seed#
Sunflower seed goes rancid faster in a hot garage than in a cold shed, and birds detect it long before you do. In a California summer the practical rule is to buy no more seed than you will use in about a month and to keep it in a sealed container somewhere cool. The full case is in storing bird seed.
Regular suet cakes soften and go greasy above roughly 90°F (32°C), which mats feathers and turns rancid quickly. Switch to no-melt dough cakes from late spring through fall, or pull suet entirely for the hottest months.
Coastal fog is the counterpart problem: seed absorbs moisture overnight, cakes in the base of a tube, and molds out of sight. Fill tubes half full in foggy months and empty them completely before each refill rather than topping up. What that looks like when it goes wrong is covered in moldy, clumped or wet seed.
Jays, squirrels and ground squirrels#
The California scrub-jay is a cacher. It does not eat at your feeder, it empties it and buries the contents. The fix is not exclusion but diversion: put whole in-shell peanuts on a separate tray 20 feet (6 m) away and let the jays work through those, then use short perches or a caged feeder for the seed you want the small birds to reach.
California adds a pest most of the country does not have: ground squirrels, which climb poles that were baffled against tree squirrels and dig under ground trays. A wide pole baffle set at least 4 feet (1.2 m) up still works, but you also need to stop feeding on bare ground where they can excavate. The pole geometry is in how to stop squirrels raiding feeders.
Plant for birds and the feeder matters less#
More than in most regions, a California yard planted for birds outperforms a yard that only has feeders. Toyon, coffeeberry, elderberry, ceanothus, native sages and buckwheats carry birds through the dry season on fruit, seed and the insects they host, and they need no water once established. Native plants for birds covers the approach, and together with cover and water it does most of the work a feeder usually gets credit for.
A California setup that works#
- A tube of black oil sunflower with short perches, on a baffled pole.
- A nyjer or fine-mesh feeder for lesser goldfinches, which in much of the state are the most reliable feeder bird you have.
- A low ground tray with white millet, October through April, for white-crowned sparrows, juncos and towhees.
- A hummingbird feeder up all year, cleaned every two to three days in summer.
- A shallow bath with a dripper, scrubbed twice a week, running May through October.
- A separate peanut tray for the jays, well away from everything else.
If you are starting from nothing, build in that order and give it a few weeks. How long a new setup takes to get found is covered in how long until birds find a new feeder.
Frequently asked questions#
Do I take my hummingbird feeder down in winter in California?
No. Anna's hummingbird is a year-round resident through the coast, the Central Valley and the southern lowlands, and birds hold winter territories around reliable feeders. Keep the feeder up and clean all year. In interior valleys that drop below freezing on winter nights, bring the feeder in after dark and put it back out at first light, or run two and swap them.
When are birds busiest at California feeders?
October through April in most of the state. Wintering sparrows and juncos arrive in fall, natural seed supply falls off, and the wet season pushes birds to concentrate. Midsummer is typically the quietest stretch, when adults are feeding insects to young and wild seed is abundant.
What seed works best in California?
Black oil sunflower for the general crowd, nyjer or sunflower chips for lesser goldfinches, and white proso millet scattered on the ground or a low tray for white-crowned sparrows, juncos and towhees. Skip mixes heavy in milo and wheat, which mostly end up on the ground.
How do I keep a bird bath usable in a drought?
Use a shallow bath, no more than 2 inches (5 cm) deep, on a timer-fed dripper rather than a wide open basin. A dripper uses very little water, replaces evaporative loss, and the sound carries much farther than still water does. Check local restrictions, which generally permit small wildlife water sources.
Why do jays empty my feeder in one morning?
California scrub-jays cache food rather than eat it, so a jay will carry off peanut after peanut until the feeder is empty. Offer whole peanuts in the shell on a separate tray away from the main feeders, which satisfies them quickly, and use short-perch or caged feeders for the seed you want the small birds to get.
