Backyard Bird Identification: 20 Common US Species

Backyard bird identification uses four clues, in this order: size and shape, color pattern and field marks, behavior, and sound. The Nature Conservancy's Midwest guide stresses learning field marks, noting where the bird feeds, and using song to split look-alikes such as downy and hairy woodpeckers. Where you live matters too: the American Bird Conservancy (ABC) lists ten birds found in yards across the US, plus separate eastern and western sets.

From ABC's guide to common backyard birds:

• American robin: orange-breasted thrush; hunts worms on lawns in spring and berries in fall and winter; may be the most abundant bird in the US and Canada.
• Mourning dove: soft, mournful call and a whistling sound from the wings at takeoff; no black collar on the neck.
• Northern mockingbird: medium, long-tailed gray songbird with white wing patches; may learn up to 200 songs and sometimes sings at night.
• White-breasted nuthatch: white face and underside, bluish back, dark crown; climbs headfirst down tree trunks; nasal "yank-yank" call.
• American goldfinch: males sunny yellow in spring and summer, females duller; eats seeds almost exclusively.
• Downy woodpecker: the smallest North American woodpecker; stubby-billed, black and white.
• Dark-eyed junco: gray sparrow with white outer tail feathers that flash in flight.
• House finch: brown finch, males with a red face and chest; introduced to the eastern US in 1939.
• Song sparrow: small, streaky brown bird with a rhythmic song, often near water.
• Black-capped and Carolina chickadees: black cap and chin, white cheeks.

ABC adds regional birds:

• East: ruby-throated hummingbird (the only one regularly breeding east of the Mississippi; males have a red throat), blue jay (bold blue, black and white, crested, often gives hawk-like calls), northern cardinal (male red with a black mask and crest; female grayish tan with the same crest and orange bill), tufted titmouse (gray with a pointed crest) and Carolina wren (rust and cinnamon with a white eyebrow; "tea-kettle, tea-kettle" song).
• West: black-billed magpie (black and white with a very long tail), rufous hummingbird (rusty males; ABC says its population fell about 67% between 1966 and 2019), Steller's jay (blue body, black crested head), spotted towhee (dark head, white wing spots, rusty sides, red eyes) and lesser goldfinch (smaller than American goldfinch, males with black or greenish backs).

• Downy vs hairy woodpecker: Wikipedia says the downy's shorter bill relative to its head is, apart from size and voice, the best field mark; the hairy also lacks the spots that the downy shows on its white outer tail feathers. The hairy is 18 to 26 cm long.
• Mourning dove vs Eurasian collared-dove: the collared-dove has a black collar on the neck; the mourning dove does not (ABC).
• Black-capped vs Carolina chickadee: mostly by range, northern half of the US versus the Southeast, and by voice: black-capped sings "fee-bee", Carolina a four-note descending song; black-capped also shows a hockey-stick-shaped white pattern on the wing (ABC).
• American vs lesser goldfinch: lesser is smaller, and breeding males have black or greenish backs rather than all-yellow bodies (ABC).
• House finch vs other red birds: the house finch is a brown, streaky finch with red limited to the face and chest; a male cardinal is red all over with a crest (ABC).

ABC reports that 2.9 billion birds have been lost from the US and Canada in less than one human lifetime, with dark-eyed juncos down by 175 million, and that more than 1 billion birds die from collisions with glass every year in the US alone. Its advice for feeder owners:

• Scrub feeders completely every few weeks with a 10% non-chlorinated bleach solution to limit diseases such as house finch eye disease and trichomoniasis.
• Think about where the feeder sits relative to windows and patio doors.
• Keep cats indoors and keep feeders out of reach of predators.
• During bird flu (H5N1) outbreaks, which ABC says have infected at least 99 wild bird species, check with health or wildlife departments before filling feeders.
• Plant native plants and avoid pesticides.

Photograph the bird side-on, then its tail and wings if it moves; a short audio or video clip helps for wrens, chickadees and other birds heard more than seen. Photograph it and the app identifies it, with free scans every day. ABC also points readers to the Cornell Lab of Ornithology's Merlin app.
