Idaho is home to more than 430 recorded bird species, from tiny hummingbirds darting through mountain meadows to eight-foot-wingspan raptors patrolling river canyons. Among the many types of birds in Idaho, five stand out for how deeply they’re woven into the state’s identity: one is even the official state bird. Whether watched from a backyard feeder or a rugged wilderness trail, these species tell the story of Idaho’s forests, deserts, and waterways better than almost any other wildlife.
This guide looks at five of the Gem State’s most recognizable birds, covering what makes each one distinct, where to find them, and how their behavior connects to Idaho’s varied landscapes. Readers curious about other small fliers might also want to check out the state’s hummingbird species found in Idaho, which share many of the same mountain and valley habitats described below.
Mountain Bluebird
The Mountain Bluebird (Sialia currucoides) is more than a pretty face in Idaho’s open country — it’s the state’s official bird. The mountain bluebird was officially adopted as Idaho’s state bird in 1931. Males are a vivid sky blue from head to tail, while females wear softer gray-blue tones that still catch the light in flight.
Spotting one is easiest during breeding season. Identifying the Mountain Bluebird is easiest during the breeding season when males perch on fence posts or branches in open fields, displaying their vivid coloration, and their call is a soft, warbling “cheer” or “few.” They rely on abandoned cavities rather than building nests from scratch. These birds are cavity nesters, often using old woodpecker holes or man-made nest boxes placed in sagebrush or grassland regions.
Look for them across open prairies and pastures rather than dense forest. In Idaho, Mountain Bluebirds are commonly found in open country such as prairies, pastures, and alpine meadows, breeding in higher elevations during spring and summer, often seen across southern and central parts of the state. Their brilliant coloring places them among the state’s most photographed birds, alongside other blue-plumaged bird species found across North America.
Pro Tip: Mountain Bluebirds readily use nest boxes placed on fence posts near open fields. Mount boxes about four to six feet high, facing away from prevailing winds, to attract a breeding pair each spring.
Bald Eagle
No bird carries more symbolic weight in Idaho’s skies than the Bald Eagle (Haliaeetus leucocephalus). Along the Sawtooth National Recreation Area’s rivers and lakes, birders regularly spot this raptor sharing airspace with osprey and mountain bluebirds. Mountain bluebirds, Sandhill cranes, bald eagles, osprey, three-toed woodpeckers, Swainson’s hawks, western tanagers, willow flycatchers, Wilson’s warblers, sparrows, kingfishers, finches, magpies, and the greater sage-grouse are among the most common species in the central Idaho Rocky Mountains.
Size is what separates the Bald Eagle from every other bird on this list. The biggest bird in Idaho is the Bald Eagle, with a wingspan of up to 8 feet (2.5 m) for females, this white-headed national bird symbol of the United States is a powerful bird of prey. That wingspan lets it soar for hours over reservoirs and river bends while scanning for fish.
Idaho’s raptor diversity as a whole is remarkable. Fifteen species of birds of prey, including hawks, falcons and eagles, can commonly be found throughout the state, a result of the variety of habitats in Idaho, from the high desert plains of the southwest to the dense forests of the north.
Bald Eagles favor the reservoirs and large rivers within that mix, particularly during winter months when northern populations move south. Occasionally, ground-foraging eagles will even take small reptiles, putting them in loose competition with predators covered in guides to Idaho’s snake species.
Important Note: Bald Eagles are protected under the federal Bald and Golden Eagle Protection Act. Disturbing an active nest or approaching too closely, even for photography, can carry legal penalties.
Osprey
The Osprey (Pandion haliaetus) is frequently mistaken for a Bald Eagle from a distance, but its narrower wings, black eye stripe, and near-exclusive fish diet set it apart. Idaho’s larger reservoirs have supported breeding pairs for decades. Bald Eagles and Osprey have nested here for many years, and have been monitored annually since the late 1970’s.
Watching an Osprey hunt is one of the more dramatic sights on any Idaho waterway. The bird hovers above the surface, then plunges feet-first to snatch fish with its sharp, curved talons, a hunting style shared with many of the state’s other fish-eating species covered in guides to water birds across different regions. Because Osprey depend almost entirely on live fish, they’re most visible near lakes, reservoirs, and slow-moving river stretches from spring through early fall before migrating south for winter.
Western Tanager
Few Idaho birds look as out of place — in the best way — as the Western Tanager (Piranga ludoviciana). This brilliantly colored bird stands out with its tropical-like appearance; males are especially eye-catching with bright yellow bodies, black wings with two white wing bars, and fiery red heads during the breeding season, while females are duller yellow with olive or gray tones. That red head coloring, unusual for a North American songbird, comes from pigments absorbed through their insect diet rather than produced internally.
Despite the bright plumage, these birds aren’t always easy to spot. You can find Western Tanagers in open conifer forests, but they stay hidden in the canopy, despite their bright coloring. These medium-sized songbirds measure about 6.3 to 7.5 inches in length and forage for insects and fruit, often remaining high in the tree canopy. Their diet leans heavily on beetles and other forest insects, connecting them to the broader insect populations described in guides to Idaho’s beetle species.
In Idaho, Western Tanagers breed in coniferous forests, especially in mountainous and northern regions, and are most often seen during spring and early summer as they migrate and settle into forested habitats. Come autumn, they head south. Winter is spent in Mexico and Central America. Their fiery coloring puts them in the same eye-catching category as the state’s orange-colored bird species, many of which share similar forest-edge habitats.
Key Insight: A Western Tanager’s red head fades slightly outside breeding season. If a male looks more orange than red in late summer, it’s likely molting into non-breeding plumage rather than being a different species.
Black-billed Magpie
The Black-billed Magpie (Pica hudsonia) is impossible to miss once you know its silhouette: a long, iridescent tail trailing behind a stocky black-and-white body. The black-billed magpie, also known as the American magpie, is a bird in the corvid family found in the western half of North America, black and white, with the wings and tail showing black areas and iridescent hints of blue and blue-green.
Magpies thrive practically everywhere in Idaho. Black-billed magpies are super common throughout the Idaho forests. This species prefers generally open habitats with clumps of trees, but can also commonly be found in farmlands and suburban areas. That adaptability places them among the same widespread corvid and songbird groups profiled in guides to black-colored birds found in Idaho.
Their intelligence and opportunistic feeding habits are part of what makes them so successful. Historically associated with bison herds, magpies now land on the backs of cattle to glean ticks and insects from them, and they commonly follow large predators, such as wolves, to scavenge from their kills. The species also walks or hops on the ground, where it obtains food items such as beetles, grasshoppers, worms, and small rodents. That ground-foraging habit occasionally overlaps with amphibian prey in wetter habitats, putting them in loose contact with species covered in guides to Idaho’s frog species.
Nesting season reveals another side of magpie behavior. The black-billed magpie builds domed nests made up of twigs and located near the top of trees, usually housing six to seven eggs; incubation, by the female only, starts when the clutch is complete and lasts 16–21 days, with a nestling period of three to four weeks. Between their bold personalities and eye-catching plumage, magpies remain one of the easiest types of birds in Idaho for beginning birders to identify on sight.
| Bird | Best Season to Spot | Typical Habitat | Notable Trait |
|---|---|---|---|
| Mountain Bluebird | Spring through summer | Open prairies, pastures, alpine meadows | Idaho’s official state bird |
| Bald Eagle | Winter (northern migrants); year-round residents | Rivers, reservoirs, large lakes | Up to 8-foot wingspan in females |
| Osprey | Spring through early fall | Lakes, reservoirs, slow-moving rivers | Feet-first fishing dives |
| Western Tanager | Spring and early summer | Coniferous mountain forests | Red head pigment from diet |
| Black-billed Magpie | Year-round | Open woodlands, farmland, suburbs | Long, iridescent black-and-white tail |
Idaho’s overall bird checklist puts these five species in good company. As of January 2022, there were 433 species on the official list recognized by the Idaho Bird Records Committee, and according to eBird data from 2021 to 2023, a rotating list shows the 30 most common birds of Idaho across backyards and wild habitats statewide. From the state-bird bluebird to the scavenging magpie, each species reflects a different corner of Idaho’s landscape, and each rewards patience with a closer look through binoculars.
