What kinds of shorebirds can you find in Montana?
Shorebirds are incredibly lively and exciting!Their showy mating displays and fierce defense of their territory make them fun to watch and observe.
Below, you will find pictures and descriptions of common shorebirds in Montana. I’ve also included some fun facts about each species. I think you will be surprised to learn that a few species of shorebirds don’t live by the shore!
Unfortunately, shorebirds can be hard to identify. First, many species look similar to each other. In addition, due to their migratory nature, they can show up in places they typically don’t visit. That said, you may want to consider purchasing the book below if you need additional help with shorebird identification.
Here are 15 COMMON Shorebirds In Montana!
#1. Semipalmated Plover
- Charadrius semipalmatus
- Adults are brown above and white below, with one black band on the breast.
- The legs and bill are orange, and the bill has a black tip.
During migration, semipalmated plovers are often seen in various open habitats. They’ll visit sandy beaches, golf courses, and salt marshes. They breed in the north, typically close to bodies of water. Occasionally, they’ll nest in a developed area like a rooftop, gravel runway, or even inside an open building.
In the breeding season, males arrive at the nesting grounds first and begin display flights over territories.When females arrive, they engage in courtship displays. Then the female will select a breeding location. Once bonded, pairs stay together for several years.
Semipalmated Plovers forage on foot. They pause to listen and look for prey, then run a few steps to peck at the ground. Sometimes you can spot them holding one foot forward and shuffling it over the sand or mud to startle creatures into moving. They will wade into the water but rarely more than an inch deep.
In the late 19th century, the population of Semipalmated Plovers declined steeply due to overhunting but has since recovered. Despite this return, hundreds of thousands of Semipalmated Plovers are hunted in South America yearly.They also face threats from oil spills and climate change.
- Charadrius vociferus
- Adults are brownish-tan on top and white below, with two black bands on the neck.
Unlike most shorebirds in Montana, Killdeer occupy dry habitats.
These birds feed primarily on small invertebrates, including earthworms, snails, and aquatic insect larvae. They also follow farm equipment, retrieving unearthed worms and insects.Killdeers are adept swimmers, even in swift water, despite spending most time foraging on land.
During the nesting season, the Killdeer is one of the best-known practitioners of the “broken-wing” display. They will feign an injury and attempt to lure predators away from their nest. They also puff up and charge at intruders such as cows to prevent them from crushing their eggs.
While rooftops attract nesting Killdeer, they can sometimes be problematic for the young. Chicks are often scared to leave the nest because of the high drop! Parents eventually lure chicks off the roof, but it can be dangerous. However, one set of chicks is known to have survived a leap off a seven-story building.

#3. Black-necked Stilt
- Himantopus mexicanus
- Adults are black above and white below with needle-like bills and rosy pink legs.
These delicate-looking birds favor open habitats with limited vegetation and shallow water. You may spot them in mudflats, grassy marshes, shallow lakes, and sewage or retaining ponds.
Like many shorebirds in Montana, Black-necked Stilts forage by wading in shallow waters. They typically grab food off the water’s surface with their bill. You might also see them catch flying insects or chase small fish into the shallows.
Nesting stilts may form a ring around an approaching predator, calling loudly, flapping their wings, and leaping up and down in what researchers call a “popcorn display.” They’ll even do this to humans who get too close! This species is also known to strike approaching humans from behind with their legs.
#4. American Avocet
- Recurvirostra americana
- Breeding adults have a rusty head and neck that turns grayish white after breeding.
- They have black and white wings, a white body, and bluish-gray legs.
These shorebirds spend most of their time in Montana foraging in shallow fresh and saltwater wetlands. These unique birds use a signature feeding style called “scything.” They sweep their slightly open bill from side to side as they walk forward, capturing prey in the water.
American Avocets have an incredible way to defend their territory. In response to predators, the American Avocet simulates the Doppler effect by giving a series of call notes that gradually rise in pitch. As a result, intruders are tricked into thinking the bird is approaching much faster than it is.
American Avocets have been known to practice “brood-parasitism.”They lay their eggs in the nests of other Avocets or species such as Mew-Gulls. Interestingly, Common Terns and Black-necked Stilts may parasitize Avocet nests, and the Avocets will raise the other species as their own.
American Avocets face the greatest threat from pollution. For example, in the western U.S., selenium leaching from the soil after rain causes low reproductive success and embryo deformities. Chicks are also susceptible to bird defects from Methylmercury, a pollutant from burning coal.
#5. Greater Yellowlegs
- Tringa melanoleuca
- Breeding adults have a dense, dark checkerboard pattern on the breast and neck that fades after breeding.
- All adults have bright yellow legs.
Greater Yellowlegs occupy various fresh and brackish wetlands in Montana. They typically prefer areas with many small lakes and ponds, scattered shrubs, and small trees, including dwarf birch, pine, and willow.
These shorebirds have a boisterous mating display! They land, run around the female, and pose with upraised wings. Once breeding occurs, both parents tend to the young and noisily fend off predators.
#6. Lesser Yellowlegs
- Tringa flavipes
- Coloration is grayish brown with fine gray streaking across the head and neck, white eye-rings, and white spots on the back and wings.
- They have vivid yellow legs.
Despite the Lesser Yellowlegs’ similar appearance to Greater Yellowlegs, they aren’t close relatives. Instead, lesser Yellowlegs are more closely related to other types of shorebirds in Montana.
These birds travel in loose flocks and are often seen with other shorebird species during migration and winter. However, they become extremely territorial during the breeding season and will chase intruders away. Lesser Yellowlegs are well known for their noisy defense of nests and chicks.
Lesser Yellowlegs are listed on the Yellow Watch List by Partners in Flight. In the early 20th century, they were heavily hunted in North America. While this practice has ended thanks to the Migratory Bird Treaty Act of 1918, hunting Lesser Yellowlegs is still common in parts of the Caribbean. They’re also heavily impacted by the continued loss of wetland habitat in their wintering range.
#7. Spotted Sandpiper
- Actitis macularius
- Adults have a grayish-brown back, plain white breast, and pale yellow bill in winter.
- Breeding adults develop dark brown speckles all over their bodies.
Spotted Sandpipers are active foragers and have a distinctive hunting style. They walk in meandering paths, suddenly darting at prey such as insects and small crabs. They bob their tail ends in a smooth motion almost constantly.
Unlike most shorebirds in Montana, female Spotted Sandpipers perform courtship displays and defend territories.
Females are sometimes polyandrous and mate with more than one male. The males will form their own smaller territories within the female’s territory and defend them from one another.
While it is still a common species, Spotted Sandpiper populations have declined in the last several decades. The decline is primarily caused by compromised water quality due to herbicides, pesticides, and other run-off pollution.
- Tringa semipalmata
- Adults are mottled gray, brown, and black in the summer and a more consistent plain gray in the winter.
- They have bluish-gray legs.
Willets are often seen in coastal areas, with populations differing slightly in ecology, shape, and calls. They inhabit open beaches, bays, and rocky coastal zones.
Willets return to their breeding grounds in the spring, making a characteristic “pill-will-willet” call in flight.
Historically, Willets were over-hunted for food until the Migratory Bird Treaty Act of 1918. Today they are threatened by the conversion of native grasslands and wetlands to agricultural areas and coastal development. In addition, adult and fledgling Willets are susceptible to collisions with power lines in their wetland nesting areas.
#9. Ruddy Turnstone
- Arenaria interpres
- Breeding males have a chestnut and black pattern on the back, similar to a calico cat.
- They have orange legs, which are brighter during the breeding season.
Ruddy Turnstones occupy different habitats each season. They nest along rocky coasts in the High Arctic during the breeding season. While migrating, they visit plowed fields and shorelines of lakes. Finally, they congregate on rocky shorelines and beaches in the winter.
These beautiful shorebirds have a unique feeding style that earned them their name. They insert their bills under stones, shells, and other objects, flipping them over to find food underneath. Several Ruddy Turnstones may work together to flip a large object.
They will also probe under seaweed and other debris. Their low center of gravity and special feet with short, sharply curved toenails allow them to easily walk on wet and slippery rocks. WATCH BELOW!
- Calidris alpina
- Breeding adults have rusty backs and crowns, black belly patches, and white underparts.
- Non-breeding adults have brown upper parts, heads, and breasts and are pale below.
During winter and migration season, Dunlins roost in coastal habitats. You’re most likely to spot them on mudflats. In addition, they visit inland areas like lakeshores, sewage ponds, and flooded fields to forage.
Dunlins forage by picking up items from the surface or probing the mud with their bills. Sometimes, this species makes a “stitching” motion, probing the ground several times per second. Additionally, their ability to forage at night allows them to take advantage of tide cycles, grabbing prey usually covered by the surf.
Some estimates show that Dunlin populations in North America have declined more than 30% since 2006. The Audubon Society also notes that their populations have noticeably declined since the 1970s, though the reason is unknown. Destruction of wintering habitat could play a role.
#11. Least Sandpiper
- Calidris minutilla
- Adults have brown upper parts and white underparts.
- They have black bills and yellowish-green legs often covered in mud.
The Least Sandpiper is the smallest shorebird in Montana!
During migration, you can spot them in coastal and inland habitats. Eastern populations of Least Sandpiper are believed to migrate up to 2,500 miles non-stop to their wintering habitats in South America.
During the breeding season, males display for the females with noisy calls and fast circular flights that end in dives. While displaying, males will aggressively defend a display territory but become less aggressive once paired.
Both parents tend their young for a while, but the females depart earlier, sometimes before the eggs hatch. Males stay at least until the chicks can fly.
- Calidris alba
- Breeding adults are spangled black, white, and rich rufous on the head, neck, and back while non-breeding adults are pale overall.
- They have black legs, bills, and eyes.
Look for the Sanderling in northeastern Montana. Predominately a coastal species, you will likely see Sanderlings on wave-washed beaches and rocky shorelines. However, they may occasionally visit inland lakeshores during migration. In addition, non-breeding Sanderlings may remain in their winter habitat year-round.
These shorebirds appear to chase the waves when foraging. As a wave recedes, they run down the beach to find sand crabs and other invertebrates stranded by the wave. They may also probe the sand with their bill for hidden prey. After foraging, Sanderlings often regurgitate sand pellets, mollusk fragments, and crustacean shells.
#13. Long-Billed Dowitcher
- Limnodromus scolopaceus
- Breeding adults have black, gold, rufous, and white upper parts with reddish underparts, while non-breeding adults are grayish above with a pale belly.
- Females have a longer bill.
Long-billed Dowitchers are typically found in freshwater environments in coastal areas. They’ll visit lakes, flooded fields, and sewage ponds. They prefer foraging areas with muddy substrate and water less than 3 inches deep.
These birds forage by wading in shallow water or walking on wet mud, slowly and deliberately moving forward and probing deeply into the mud with their bill. Their bills have tactile receptors called Herbst corpuscles, allowing the birds to locate prey by touch. In addition, they often feed in darkness and have excellent night vision.
Due to their remote breeding range, little information is available on the populations of Long-Billed Dowitchers. Partners in Flight lists them as a species of low conservation concern. However, Long-Billed Dowitchers may be threatened by the loss of wetland habitat, climate change, and pollution.
#14. Wilson’s Snipe
- Gallinago delicata
- They are intricately patterned in buff and brown stripes with a white belly.
Wilson’s Snipes are stocky thanks to their extra-large pectoral muscles that make up nearly a quarter of their weight, which is the highest percentage of any shorebird in Montana. Their extra muscle means they can reach incredible speeds in flight, up to 60 miles per hour. Their fast, erratic flights make them difficult targets for predators.
These birds prefer wet, marshy habitats. You may spot them in bogs and flooded agricultural fields during winter and migration. They tend to avoid areas with high, dense vegetation.
Wilson’s Snipes are well known for their dramatic courtship displays. Typically males but sometimes females circle and dive over their breeding territory, and the air rushing over their outspread tail feathers creates a haunting, whirring “hu-hu-hu” sound. They may complete this display for courtship, advertising and defending territory, or warding off potential predators. WATCH BELOW!
Predators have difficulty sneaking up on Wilson’s Snipes because these birds’ eyes are set so far back on their heads.As a result, they can see almost as well behind them as they can to the front and sides!
#15. Wilson’s Phalarope
- Phalaropus tricolor
- The coloration is grayish with cinnamon highlights.
- Breeding females are more colorful than males, while non-breeding adults are pale gray above and white below.
Wilson’s Phalaropes are very social throughout the year, nesting in small colonies and traveling in large flocks. You can spot them at salty lakes during migration, but they may also visit sewage treatment plants, ponds, and coastal marshes. They prefer to breed in areas with shallow freshwater like marshes, wetlands, and roadside ditches.
Wilson’s and other phalarope species have a polyandrous mating system where the females typically mate with multiple males. Females may vie for males with aggressive posturing that sometimes leads to fights. Females also perform courtship displays. Once paired, the female lays a clutch of eggs and then abandons the male to seek out another.
These shorebirds have a tremendous appetite and are known to eat so much that they sometimes double their body weight.Occasionally they get so fat they can’t even fly, and researchers can catch them by hand!
