Backyard Birds: Identify the Common Ones by Sight

Before color, decide whether the bird is sparrow-sized, robin-sized or crow-sized. Field guides use those three benchmarks because they are the ones people can judge without a measurement, and they cut the candidate list by more than half in one step.

Then watch where it feeds. A bird hopping on the ground under the feeder, a bird clinging to the side of a tube, a bird working up a tree trunk and a bird that only visits the suet cage are usually four different species, and that behavior stays consistent day after day.

Project FeederWatch tracks more than 130 species at North American feeders and lets you filter them by winter region, food and feeder type, which is the honest way to say that no single list of backyard birds is right for the whole country.

• Northern Cardinal: the male is the only eastern bird that is all red with a crest; the female is duller but shares the crest, the large pinkish bill and the long tail. 8-9 in long.
• American Robin: brick-red breast, gray back, white marks around the eye. 8-11 in, wingspan 12-16 in.
• Mourning Dove: 9-13 in, long pointed tail with white spots in flight, black spots on the wings.
• Blue Jay: blue above with a crest, black necklace, white wing-bars and tail corners. It can imitate the scream of a Red-shouldered Hawk.
• House Finch: the male has a red eyebrow, forehead, throat and chest; the female has a plain brown face and blurry streaks below. 5-6 in.
• American Goldfinch: bright yellow with black wings, tail and forehead in summer; yellowish-brown to gray in winter, always with bold wing-bars. Its flight is deeply undulating.
• Dark-eyed Junco: white outer tail feathers; slate-gray in the East, black-hooded with a chestnut back in the Oregon form. It forages on the ground under the tray.
• Black-capped Chickadee: black cap and bib, gray back, buff sides, with a buzzy chick-a-dee-dee-dee.
• Tufted Titmouse: gray and white with a perky crest, black forehead and rusty sides, whistling peter-peter-peter.

Downy and Hairy Woodpecker are the classic backyard pair. Downy is the smallest woodpecker in North America, 5-7 in, with a very short stubby bill and black bars on the white outer tail feathers. Hairy is 7.1-10.2 in with a bill nearly as long as its head and clean white outer tail feathers. Bill length beats overall size, because size is hard to judge on a tree trunk.

Red-bellied Woodpecker is robin-sized, 9.4 in, with narrow black and white bars on the back and a buffy brown face and chest. The red on the belly is usually hard to see, which is why the name confuses people; males have red on the nape, forehead and crown, females only on the nape.

White-breasted Nuthatch forages head-first down the trunk and calls a nasal yank-yank. Males have a black crown stripe, females often gray.

Carolina Wren is chestnut above and butterscotch below with a bold white eyebrow, and its loud tea-kettle song carries all year. Audubon notes the northern edge of its range moves north in mild winters and retreats after severe ones.

House Sparrow. The male has a black bib, white cheeks, a gray crown and a chestnut nape; the female has a pale buff eyebrow, a plain gray chest and black-and-buff stripes on a brown back. It was released in New York City in 1851 and in North America it lives around buildings, avoiding unaltered natural habitat.

European Starling. Black with purple and green gloss and a bright yellow bill in spring and summer; heavily white-spotted with a duller bill in fresh fall plumage. About robin-sized, 8.1-9.1 in. It was brought to North America in 1890 and now occupies most of the continent, gathering in immense flocks in fall and winter.

Both matter for a practical reason beyond identification: they are among the non-native species to which the Migratory Bird Treaty Act does not apply, along with the Rock Pigeon. Native species, including everything else on this page, are protected.

Windows are the one thing worth fixing before anything else. The U.S. Fish and Wildlife Service says more than one billion birds collide with glass in the United States every year, and that most fatal collisions happen at homes and buildings shorter than four stories. The remedy is cheap: mark the outside of the glass with a repeating pattern of dots about a quarter of an inch across and no more than two inches apart. Parachute cord curtains cost about 11 cents per square foot and tempera paint about 13 cents per square foot, by the agency's own figures.

Water brings in species that never touch a feeder, including warblers and thrushes. Keep it shallow and clean it as often as the feeders.

If you want to put what you see to use, the Great Backyard Bird Count runs for four days each February, coordinated by the Cornell Lab of Ornithology, the National Audubon Society and Birds Canada; fifteen minutes on one day is enough to take part.

Project FeederWatch, the Cornell Lab's winter feeder count, gives the closest thing to a real answer. In winter 1996-97 Cornell reported the Dark-eyed Junco at 83.03% of North American feeders, followed by House Finch at 70.12%, American Goldfinch 69.50%, Downy Woodpecker 69.10%, Blue Jay 66.52%, Mourning Dove 64.91%, Black-capped Chickadee 59.62%, House Sparrow 59.45%, Northern Cardinal 56.36% and European Starling 52.59%.

The order shifts by region and year. The Bay Journal reports that in winter 2023-24, Black-capped and Carolina Chickadees were the most common species at the 9,700 FeederWatch sites in the Northeast region, followed by Dark-eyed Juncos, Northern Cardinals, Downy Woodpeckers and Blue Jays.

So "the most popular backyard bird" depends on where and when you look, but juncos, chickadees, cardinals, Downy Woodpeckers and Blue Jays are near the top in both counts, nearly thirty years apart.

A backyard list from one part of the country can be half wrong in another.

• Coastal California: the Santa Clara Valley Bird Alliance's backyard list includes California Scrub-Jay, Oak Titmouse, Chestnut-backed Chickadee, Bushtit, Anna's Hummingbird, Black Phoebe, California Towhee, Nuttall's Woodpecker and Lesser Goldfinch, none of which an eastern guide will show you. It also lists the Cooper's Hawk, which hunts at feeders.
• East Texas Piney Woods: The Woodlands Township's list includes Carolina Chickadee, Carolina Wren, Eastern Phoebe, Indigo Bunting, Ruby-throated Hummingbird and Orange-crowned Warbler. The township notes that more than 800 bird species occur in North America and as many as 500 in Texas alone.

Use a list made for your county or state, and check the range map before settling on a name.

Birds & Blooms matches common backyard birds to the food that brings them in:

• American Goldfinch: thistle (nyjer) feeders and garden seed heads.
• Northern Cardinal and Black-capped Chickadee: black oil sunflower seed.
• Blue Jay and White-breasted Nuthatch: peanuts.
• Downy, Hairy and Red-bellied Woodpeckers: suet.
• Eastern Bluebird and Northern Mockingbird: mealworms; mockingbirds also come to berry bushes.
• Baltimore Oriole: orange halves and grape jelly.
• Ruby-throated Hummingbird: sugar-water feeders or nectar flowers.
• American Robin: mostly insects and worms, so a feeder rarely brings one in.

The Woodlands Township sums up what a yard needs as food, clean water and shelter, and recommends native plants as well as feeders. More on seed types is on the bird seed and feeders page.

Every source agrees on the near distance: a feeder within 3 feet of a window is safer, because a bird that flushes from it cannot build up enough speed to be hurt by the glass. On the far distance the advice differs. The Anchorage Daily News (November 2023) and House Digest say beyond 30 feet; Birds & Blooms says more than 10 feet. The zone in between is where collisions happen.

Birds & Blooms also advises hanging the feeder at least 10 feet from anything a squirrel could jump from, if you use a baffle, and planting shrubs nearby so birds have cover from predators. The window-marking advice above still applies wherever the feeder goes.

Feeder counts tell you which birds visit; population estimates tell you which are most numerous. Audubon's online field guide gives an estimated population for each species:

• American Robin: about 370 million.
• European Starling: about 250 million, not native.
• Dark-eyed Junco: about 220 million.
• Mourning Dove: about 150 million.
• Northern Cardinal: about 130 million.
• American Goldfinch: about 44 million.
• House Finch: about 40 million.
• Downy Woodpecker: about 13 million.

So the most numerous bird and the most frequent feeder visitor are not always the same species, and a "most popular" list depends on which of the two you count.

Audubon's guide to 20 common birds (Andrew Del-Colle, January 2018) is a good checklist for learning the familiar species one at a time. It covers American Robin, Northern Cardinal, Blue Jay, Steller's Jay, Mourning Dove, American Crow, European Starling, Northern Mockingbird, Black-billed Magpie, Dark-eyed Junco, Black-capped Chickadee, White-breasted Nuthatch, Tufted Titmouse, House Sparrow, House Wren, House Finch, American Goldfinch, and Downy, Hairy and Red-bellied Woodpeckers.

The list mixes species from different regions, so few yards will have all 20. The three woodpeckers are compared on the woodpecker identification page.

The Nature Conservancy's Midwest guide adds details that help in that region:

• State birds: the American Robin is the state bird of Michigan and Wisconsin; the Northern Cardinal of Illinois, Indiana and Ohio.
• Chickadees: Black-capped and Carolina Chickadees are told apart by location or song, a 2-3 note song for Black-capped and 4 or more notes for Carolina, and they can hybridize where their ranges meet.
• Hummingbirds: the Ruby-throated Hummingbird is the only hummingbird that breeds in the Midwest; males arrive first in spring and head south by early August.
• Cooper's Hawk at the feeder: if one visits regularly, take the feeders down for a while and it will move on.
• Merlin Bird ID: recommended as a free tool that identifies birds by description, photos or songs.

A photo taken through the window is often enough. Get the whole bird in the frame, side-on if you can, with the bill and tail visible.

• BirdLens: photograph it and the app identifies it.
• Merlin Bird ID: the Cornell Lab's free app has a Photo ID mode as well as a question-and-answer mode; Wikipedia notes it covers about 3,000 species.
• Google Lens: in the Google app, Google Photos and Chrome, it searches from a picture instead of words.

Then check the answer against your region and season. The American Bird Conservancy's advice for beginners applies here too: note the season and place, and learn the 20 to 50 most widespread species in your area first, so an unusual answer stands out.

Eastern lists miss several of the most common western yard birds. The American Bird Conservancy's guide to common backyard birds (October 31, 2022) picks out these:

• Black-billed Magpie: black and white with a very long tail; it roams in loose flocks and builds large domed nests. The Yellow-billed Magpie lives only in central and coastal California.
• Steller's Jay: blue body with a crested black head, common in western conifer forests and not shy of people.
• Spotted Towhee: dark head and back, white spots on the wings, rusty sides and red eyes. It scratches in leaf litter with both feet; it was treated as one species with the Eastern Towhee until the 1990s.
• Lesser Goldfinch: smaller than the American Goldfinch; breeding males have black or greenish backs with yellow underparts. ABC says it is spreading north to Washington and Idaho.
• Rufous Hummingbird: rusty-colored and breeding as far north as southern Alaska.

ABC also notes two details that help anywhere: the Northern Mockingbird can learn up to 200 songs, and the Blue Jay often gives hawk-like calls before it comes to a feeder.

Crowded feeders spread disease. The American Bird Conservancy says feeders should be completely scrubbed with a 10 percent non-chlorinated bleach solution every few weeks, which reduces the spread of House Finch eye disease and trichomoniasis.

Bird flu is the other reason. In its October 2022 article ABC reported that H5N1 had spread through much of the continental United States and infected at least 99 wild bird species, and advised checking local health or wildlife departments during outbreaks.

Common does not mean safe. The American Bird Conservancy cites a loss of 2.9 billion birds from the United States and Canada in less than one human lifetime, including 175 million Dark-eyed Juncos and 93 million White-throated Sparrows. It says the Rufous Hummingbird declined by about 67 percent between 1966 and 2019 and is listed as Near Threatened.

ABC's list of what a yard can do is short: plant native plants, avoid pesticides, keep cats indoors and treat windows that birds hit.

Birds in the yard mean the yard is supplying at least one of the four things they need: food, water, cover or a place to nest. Margaret Roach's habitat list at A Way to Garden puts water first, needed 12 months a year and preferably moving, followed by less mown lawn, edge plantings of shrubs, evergreens and fruiting plants, a brush pile and nest boxes. Each of those draws a different group: seed eaters to feeders and seed heads, thrushes and warblers to water, sparrows and wrens to brush, bluebirds and swallows to boxes.

So a new species showing up usually tells you something changed: a shrub started fruiting, the bird bath was filled, migration is passing through, or a hard freeze pushed birds toward reliable food.

Yes, for the yard as well as for the birds. Audubon California lists the jobs birds do: pollination, pest control, seed dispersal and shaping the landscape. Roach's point is simpler: bugs are bird food, and most birds are at least partly insectivorous, which is why she keeps her garden free of pesticides.

The responsibility runs the other way too. The U.S. Fish and Wildlife Service's estimates of human-caused bird deaths put cats at 1.4 to 3.7 billion birds a year, a median of about 2.4 billion, the largest single cause it lists, with vehicles at 89 to 340 million. A yard that attracts birds should keep cats indoors, treat windows and clean feeders.
