20 Warblers You Can Find in California: A Birder’s Field Guide
September 27, 2026
Warblers in California put on one of the most dramatic bird shows in North America each spring and fall. Spring transforms California into a bustling avian highway from March to May, and along the Pacific Flyway, Point Reyes becomes especially active with migrating warblers, thrushes, and flycatchers arriving in waves. Some of these small, fast-moving songbirds stay to breed, others pass through for only a few days, and a handful stick around all winter.
This guide walks through 20 warbler species that regularly show up across the Golden State, from common backyard visitors to rare treats that make experienced birders grab their binoculars. Each entry covers what the bird looks like, where it tends to turn up, and when to watch for it. Eurasia and Africa account for 350 warbler species, while the New World has its own 120, and New World warblers are often brightly colored, unlike their typically drab Old World relatives — which helps explain why California’s warblers are such a rewarding group to chase.
Warbler activity in the state falls into a few predictable patterns. The table below breaks down what to expect before the species-by-species rundown.
| Timing Category | What to Expect |
|---|---|
| Year-round residents | Stay in California all year, often in shrubby or wooded habitat |
| Summer breeders | Arrive in spring, nest locally, then leave by early fall |
| Winter visitors | Show up in fall and stay through the cold months |
| Migration-only transients | Pass through briefly during spring or fall migration, rarely staying long |
Pro Tip: The most migration activity happens during early mornings, roughly one to three hours after sunrise, when nocturnal migrants land to forage. Plan your warbler walks accordingly for the best chance of a good sighting.
Beyond Point Reyes, a few other spots consistently produce strong warbler counts. Wawona Meadow and Mariposa Grove are particularly productive locations within Yosemite, while Andrew Molera State Park along Big Sur offers excellent riparian habitat with opportunities to see migrants passing through. Pairing a visit to one of these areas with an early start is one of the simplest ways to boost your Northern California birding list in a single outing.
1. American Yellow Warbler
The American yellow warbler (Setophaga petechia) is the warbler most people picture when they think of the group, and for good reason. It is the most common warbler in North America, with an estimated population of 90 million birds. The American Yellow Warbler is California’s most prevalent warbler species and is found all over the state.
In summer, the species arrives in April or May and breeds in the coastal mountains and the Sierra Nevada, favoring streamside deciduous woods and thickets, though it is largely absent from the Central Valley and the southern and eastern deserts. Look for it in brushy habitat near water, including field edges, forests, canyons, stream sides, and orchards. Its plumage is uniformly buttery yellow, with males showing chestnut streaks on the breast.
There is also a population of wintering yellow warblers that spend the cold months in Southern California and Arizona. Remarkably, there are 35 subspecies of yellow warblers spread across North and South America. If bright plumage is what draws you to this species, the state has plenty more where that came from — check out this roundup of yellow birds in California for other species to watch for.
2. Palm Warbler
The palm warbler (Setophaga palmarum) is easy to identify even at a distance thanks to its habit of constantly pumping its tail up and down while foraging on the ground. This species breeds in the boreal bogs of Canada and typically winters along the Gulf Coast and Caribbean, but small numbers regularly drift into California during fall migration and winter.
Warblers in California during migration include the Palm Warbler alongside species like the Black-and-white Warbler, American Redstart, and Chestnut-sided Warbler. Look for palm warblers in open, weedy fields and along coastal scrub, where they forage low to the ground rather than high in the canopy like many of their relatives. Read more about seasonal warbler patterns in California for a full breakdown of which species show up when.
3. Black-and-white Warbler
The black-and-white warbler (Mniotilta varia) looks like nothing else on this list. Its bold zebra-striped plumage and habit of creeping along tree trunks and branches, probing bark crevices for insects much like a nuthatch, make it one of the more distinctive vagrants a California birder can hope to find.
This species breeds across the eastern half of the continent and is not expected in the state as a regular visitor, but it shows up nearly every year along the coast during fall migration. Scattered individuals sometimes linger through winter at well-vegetated parks. Anyone drawn to bold black-and-white patterning might also enjoy this guide to black birds found across California.
4. American Redstart
Male American redstarts (Setophaga ruticilla) are hard to miss once spotted, with jet-black plumage set off by bright orange patches on the wings and tail. They flash that tail open and closed while foraging, a behavior thought to startle insects into flight so the bird can snatch them mid-air.
Like the previous two species, the American redstart is a scarce but annual migrant along the California coast, most often turning up in September and October. Riparian corridors and coastal willow thickets tend to be the most productive places to look, particularly the same waterside habitats favored by many other water-associated birds in California.
5. Chestnut-sided Warbler
The chestnut-sided warbler (Setophaga pensylvanica) breeds across the northeastern United States and southern Canada, where males in spring show off a crisp white face and chestnut streaking along the flanks. By the time this species reaches California in fall, most individuals have molted into a much plainer lime-green and gray look that can trip up even experienced birders.
Fall vagrants tend to show up in weedy edges, shrubby thickets, and coastal scrub, where they forage actively for insects. Because warblers rely heavily on protein-rich prey during migration, understanding what birds eat to survive long journeys helps explain why these fragile-looking migrants can cover such enormous distances.
6. Northern Waterthrush
Despite the name, the northern waterthrush (Parkesia noveboracensis) is not a thrush at all — it is a warbler that has adapted to a very specific lifestyle. It walks rather than hops along muddy stream banks and pond edges, constantly bobbing its tail as it searches for insects and small invertebrates.
This species is one of the regular migration-only warblers recorded in California, appearing during spring and fall passage rather than sticking around to breed. Riparian willow thickets and shaded creek edges are the best places to find one. It shares that watery habitat preference with several species covered in this guide to California’s water birds.
7. Tennessee Warbler
The Tennessee warbler (Leiothlypis peregrina) is a plain, olive-and-white bird named after the state where it was first collected, even though it neither breeds nor winters there in any numbers. It breeds across the boreal forests of Canada and the northern United States, favoring recently disturbed woodland edges.
In California, this species is a rare but expected fall migrant, usually found singly among mixed flocks of other small songbirds along the coast. Its short, simple insect-hunting behavior and lack of distinctive markings mean it often gets overlooked entirely unless a birder is specifically checking every warbler in a flock.
8. Northern Parula
The northern parula (Setophaga americana) is one of the smallest warblers on this list, with blue-gray upperparts, a yellow throat and breast, and a broken white eye-ring. In the southeastern United States it nests in hanging clumps of Spanish moss, a habitat that does not exist in California.
The northern parula appears in California primarily during migration, alongside other transients such as the Tennessee Warbler and Blackburnian Warbler. Its blue-toned back places it among a small group of California species with genuinely blue plumage worth learning to recognize — see this guide to blue-colored birds for more.
9. Blackburnian Warbler
Few warblers generate more excitement among California birders than the blackburnian warbler (Setophaga fusca). Breeding males have a blazing orange face and throat set against black-and-white plumage, a combination that has earned the species nicknames like “firethroat” among fans of the family.
Finding species like the blackburnian warbler, Cape May warbler, or Townsend’s warbler usually requires getting out and birding in the field rather than waiting at a feeder. This species breeds in boreal conifer forests far to the north and east, and any California record is treated as a genuine highlight of the season. Learning the timing tricks outlined by Cornell Lab’s spring warbler-watching tips can improve the odds of connecting with a rarity like this one.
10. Magnolia Warbler
The magnolia warbler (Setophaga magnolia) gets its name from an unfortunate coincidence — an early collector happened to shoot the first specimen out of a magnolia tree, even though the species has no particular attachment to that tree. It breeds in young conifer stands across Canada and the northern United States.
This warbler shows bold black streaking across a yellow breast and a distinctive white band across the middle of the tail, visible in flight. In California it is a scarce but annual fall migrant, generally found in coastal scrub alongside other boldly patterned songbirds similar to those covered in this guide to black-marked birds statewide.
11. Virginia’s Warbler
Virginia’s warbler (Leiothlypis virginiae) is a plain gray bird enlivened by a yellow rump and breast patch, and it favors a very different habitat than most warblers on this list. Rather than woodlands or riparian corridors, it breeds in dry pinyon-juniper woodland and scrub oak in the mountains of the Great Basin and the southwestern United States.
In California, small breeding populations occur in isolated desert mountain ranges in the eastern part of the state. Birders exploring that same high desert scrub often cross paths with other specialists of the region, including several species profiled in this guide to California’s quail species.
12. Black-throated Blue Warbler
Male black-throated blue warblers (Setophaga caerulescens) are unmistakable, with deep slate-blue upperparts, a jet-black throat and face, and a crisp white belly. Females look so different that early ornithologists once classified them as a separate species. This warbler breeds in eastern hardwood forests and typically winters in the Caribbean.
California records are rare but reliable in small numbers each fall and winter, with a few individuals occasionally overwintering at well-stocked backyard feeders along the coast. For birders with a broader interest in the family beyond the species regularly seen in the state, additional resources can help fill in the gaps, including detailed regional accounts like the one at John R. Cammidge’s warblers of California.
13. Canada Warbler
The Canada warbler (Cardellina canadensis) is easy to identify once seen well, thanks to a bold black “necklace” of streaking across its bright yellow breast, set against blue-gray upperparts. It breeds in the wet understory of boreal forests across Canada and the northern United States.
This species is one of the rarest warblers to appear in California, with most records coming from fall coastal vagrancy. Because it forages low in dense, shaded vegetation, spotting one usually takes patience and a willingness to stand quietly near thick brush for longer than most casual birders would expect.
14. Prothonotary Warbler
Named for the golden robes worn by prothonotaries in the Catholic church, the prothonotary warbler (Protonotaria citrea) is a striking bird with a solid golden-yellow head and body set against blue-gray wings. It is one of the few warblers that nests in tree cavities, typically over swampy water in the southeastern United States.
California has no breeding population, but the species turns up as a genuine rarity most years, usually in riparian or wetland vegetation similar to habitat covered in this guide to California’s water birds. Any confirmed sighting tends to draw birders from across the region.
15. Orange-crowned Warbler
The orange-crowned warbler (Leiothlypis celata) is one of the plainer members of the family, but its orange crown patch, usually hidden unless the bird raises its feathers, gives it its name. This species is present in California all year, alongside year-round residents like the common yellowthroat and black-throated gray warbler.
Look for orange-crowned warblers in open, shrubby habitats with plenty of insects and berries, which are this species’ favorite foods. Its high, trilling song lasts about one second, is repeated often, and dips in pitch slightly at the end. That subtle song is often the easiest way to detect one before it comes into view, a detail covered well in Bird Watching HQ’s California warbler guide.
16. Wilson’s Warbler
Wilson’s warbler (Cardellina pusilla) is a small, lemon-yellow bird with an olive back and, in males, a neat black cap. Its plumage is lemon-yellow across the whole body with light chestnut streaks on the chest, and males are somewhat brighter than females.
Unlike other warblers in California, Wilson’s warblers are more comfortable on the ground or in the forest understory, which makes them easier to spot without craning your neck. They often nest on the ground, concealed in shrubs at forest edges. Their song is a high-pitched, quick “tchee-tchee-tchee-tchee” that repeats often. This species breeds widely in riparian thickets, including many of the same streamside corridors favored by hummingbirds in Southern California.
17. Hermit Warbler
The hermit warbler (Setophaga occidentalis) is a conifer forest specialist with a bright yellow head, black throat in males, and gray-and-white body. The Pacific Flyway is famous for the number of warblers passing through, and this striking sunny-headed species is one to include on any warbler watch list.
The species returns to its breeding grounds in forested areas with conifer trees, with greatest numbers arriving in places like Marin County by April. Tall Douglas fir and mixed conifer stands in the Coast Ranges and Sierra Nevada are the most reliable places to find breeding pairs. For a deeper dive into where and when to look, Lyric Wild Bird Food’s spring migration guide covers this species alongside other Central Valley highlights.
18. Black-throated Gray Warbler
The black-throated gray warbler (Setophaga nigrescens) shares breeding territory with the hermit warbler and looks superficially similar in structure, but its plumage is strikingly different — gray, black, and white striping with a small yellow spot in front of the eye. This species is present in California all year, making it one of the more dependable warblers for birders to find outside migration season.
Its greatest numbers begin returning to breeding grounds in places such as Marin County by April, favoring the same conifer forests preferred by the hermit warbler. Birders working that same stretch of coastal forest north of the Golden Gate often report both species on the same outing, an experience detailed further at Warbler Watch’s guide to Northern California viewing spots. The same region draws strong numbers of Northern California hummingbirds during the same April window.
19. Yellow-rumped Warbler
The yellow-rumped warbler (Setophaga coronata) is by far the most numerous warbler in California during the colder months. It tops the list of warblers present in the state during winter, alongside species like Townsend’s warbler and the Nashville warbler.
There are two subspecies of this warbler in California, closely related but distinguished by their throat patch, which is yellow in Audubon’s warblers and white in Myrtle warblers. They are an active species known for catching insects in midair. During winter, they visit feeders offering sunflower seeds, raisins, suet, and peanut butter, and they also eat winter berries. If you plan to attract them to a backyard feeder, it is worth checking this list of plants that are poisonous to birds before landscaping the area they will be visiting.
20. Townsend’s Warbler
Townsend’s warbler (Setophaga townsendi) rounds out the list with one of the boldest facial patterns of any California warbler — black cheeks and crown set against a bright yellow face and breast. Along with the blackburnian and Cape May warblers, this species is considered one of the true jewels of migration that birders actively seek out.
Townsend’s warbler is a regular winter visitor across California, arriving in fall and staying through the colder months before heading back north to breed. Coastal conifer forests and eucalyptus groves are reliable wintering habitat. This species rounds out a group of yellow-faced warblers worth comparing side by side with the state’s other yellow birds.
With 20 species covered, from the everyday American yellow warbler to rarities like the Canada warbler and prothonotary warbler, California offers one of the richest warbler-watching experiences in the country. Checking the bar charts under the “Explore Data” tab on eBird, selecting a state and county, then clicking on a given month, shows how frequently each species occurs in that area down to the week. Pairing that data with real-time migration forecasts from BirdCast turns a hopeful walk in the woods into a genuinely well-timed outing.
Spring and fall each bring their own rewards. Spring warbler migration runs primarily through April and May, when breeding plumage is at its brightest, while fall brings a longer, quieter wave of birds working their way south. Whichever season draws you outside, keeping a list of what birds eat to survive migration in mind helps explain why even the smallest warbler can travel thousands of miles between two backyard sightings.
