Birds can be surprisingly large, especially if they spread their wings to an immense size and there are some very large birds in Maryland.
- The largest bird by weight in Maryland is the Mute Swan at 416 ounces
- The largest bird by length in Maryland is the Trumpeter Swan at 72 inches
- The largest bird by wingspan in Maryland is the American White Pelican at 110 inches
These are the largest birds in Maryland in order by weight but check out the lists at the end to find out those largest by size and wingspan.
With their impressive size they should be fairly easy to spot, but how many can you find?
23 Large Birds In Maryland:
1. Mute Swan
Mute Swans are non-native species in Maryland that can be spotted in the state all year.
Mute Swans are one of the largest and heaviest flying birds. They are non-native and were introduced to grace ornamental lakes and ponds but now have escaped into the wild and bred. They cause problems for native wildlife and can be aggressive.
They are entirely white, with long, graceful necks, orange bills with a large, black basal knob, black around the base of the bill, and black legs. Adults look alike, although males are larger than females.
- Cygnus olor
- Length: 56 – 62 in (142 – 157 cm)
- Weight: 416 oz (11789 g)
- Wingspan: 84 – 96 in (213 – 244 cm)
You can find numerous Mute Swans in city parks, protected bays, and lakes. You may also find them on shallow wetlands, rivers, and estuaries.
Mute Swans spend most of their time floating on water. They forage for underwater vegetation, and this is their staple diet when on water. They may also forage for food on land, feeding on grass and agricultural crops.
Mute Swans Call:
Fun Fact: Adult swans are highly protective of their young and will aggressively defend them when they sense danger or threats. They will hiss as a warning and will immediately chase and attack the predator if the warning is ignored.
2. Trumpeter Swan
Trumpeter Swans are very rare in Maryland, but a few have been spotted in the state.
The Trumpeter Swan has the distinction of being the longest and heaviest living bird native to North America. It is also recognized as the heaviest flying bird in the world.
Trumpeter Swan adults are entirely white except for their black bills, legs, and feet. There is a black patch on their face, seemingly connecting their eyes to their bills. Their heads and neck may occasionally show some rust-brown coloring because of their contact with iron elements in wetland soils.
Juvenile Trumpeter Swans are mostly dusky-gray, with a pink center on their black bills.
- Cygnus buccinator
- Length: 58 – 72 in (147 – 183 cm)
- Weight: 401.6 oz (11381 g)
- Wingspan: 72 – 102 in (183 – 259 cm)
You can find Trumpeter Swans in marshes, lakes, and rivers with dense vegetation. They breed in open areas near shallow waters. They are sometimes seen on agricultural fields, too.
In water, Trumpeter Swans usually eat aquatic plants and vegetation, which they can reach with their bills underwater. With their long necks, they are able to reach plants in deeper water, even going as far as tipping, like a dabbling duck, to get at their food.
Trumpeter Swans Call:
Fun Fact: Trumpeter Swans generally mate for life. When nesting, there is always one adult that stays with the nest. They are both territorial and aggressive when it comes to protecting their nesting area.
3. Wild Turkey
Wild Turkeys are spotted in Maryland all year but they are most common from March to September. They are recorded in 2% of summer checklists submitted by bird watchers for the state.
Wild Turkeys are the ancestors of domesticated turkeys and the heaviest among Galliformes. Their bodies look spherical and plump when they’re puffed and preening.
Adult male Wild Turkeys have small, bald, red-and-blue heads with fleshy growths called caruncles. They have red wattles hanging from their necks and throats.
They have snoods (a fleshy flap on the bill) that expand, elongate, and change color depending on their emotions, like when they’re excited or threatened.
Males have long, dark brown fanned tails with rusty or chestnut tips. Their body feathers are blackish or dark but usually have a glossy combination of red, purple, green, copper, bronze, and gold.
Adult female Wild Turkeys are smaller than males and they’re less colorful, mostly having bodies with shades of brown and gray.
- Meleagris gallopavo
- Length: 43.3 – 45.3 in (110 – 115 cm)
- Weight: 88.2 – 381.0 oz (2500 – 10800 g)
- Wingspan: 49.2 – 56.7 in (125 – 144 cm)
You can find Wild Turkeys in mature, mixed forests with oaks and pines with a good balance of cover and openings. Pastures, fields, and orchards are usually preferred habitats.
Wild Turkeys usually forage on the ground for acorns, nuts, and other seeds and berries. They scratch around and under leaves on the ground but sometimes they also climb shrubs and low trees for fruits. They also eat salamanders, snails, beetles, and other insects. They may visit backyard feeders too.
Fun Fact: Male Wild Turkeys court in groups. They puff their feathers, spread their tails, and gobble to attract females. Watch the colors of their heads and necks change depending on a Wild Turkey’s mood.
4. American White Pelican
American White Pelicans are rare or accidental species in Maryland, and although there have been some sightings all year, they are mainly spotted during winter, from November to March, in the south of the state.
American White Pelicans are large soaring birds that have the second-largest average wingspan of any North American bird.
Non-breeding adult American White Pelicans are white all over, except for black flight feathers that are only visible when in flight or when the wings are spread. Breeding adults grow a yellow plate on their upper bills, like a horn.
- Pelecanus erythrorhynchos
- Length: 60 – 63 in (152 – 160 cm)
- Weight: 246.4 oz (6983 g)
- Wingspan: 96 – 110 in (244 – 279 cm)
American White Pelicans breed in remote lakes inland in North America before spending the winter on the southern Pacific Coast of the US, the Gulf of Mexico, Mexico, and Central America. They can be spotted during migration in western and central US states.
You can find American White Pelicans in shallow freshwater lakes, wetlands, and edges of lakes and rivers. In the winter, you can find them in coastal bays, inlets, and estuaries where they forage in shallow water and rest on sandbars.
American White Pelicans mostly eat fish. They swim on the surface and capture their prey through their huge bills.
American White Pelican calls: These birds are usually silent or only make a few grunts. However, the young can be noisy in the large colonies begging for food.
Fun Facts: The long and huge bill of the American White Pelican is capable of holding three gallons of water. When it scoops up fish from the sea, it tilts its bill down to drain the water so it can then swallow the fish that’s left inside its throat sac.
5. Canada Goose
Canada Geese are very common in Maryland that are spotted in the state all year. They appear in 26% of summer checklists and 39% of winter checklists.
Canada Geese are large, long-necked geese recognized for their black head and easily identifiable white chin straps, and loud honking calls.
Their bodies are brown with a tan or pale chest and white rump. The color of the bodies among the subspecies may be shades of gray or brown. Their legs and webbed feet are black.

- Weight: 230.09 oz (6521 g)
- Wingspan: 70 – 75 in (178 – 190 cm)
As their name would suggest, Canada Geese breed in Canada and migrate for the winter to southern US states, but those in northern US states remain all year and do not migrate. They are also found in western Europe.
You can find Canada Geese practically anywhere. They are often seen near lakes and rivers, basically, anywhere there’s a body of water and an abundant food source.
In some places, their population has risen considerably and they’re considered pests.
Canada Geese mainly eat grasses when they’re on land and small aquatic insects and fish when they’re on the water, but will raid your trash can if they can.
Canada Goose Call:
Fun Fact: During the breeding season, adults lose their flight feathers because it coincides with their molting season. They only regain their feathers after twenty to forty days, just in time for them to fly with their young.
6. Bald Eagle
Bald Eagles can be spotted all year in Maryland, but their numbers increase from August to May. They occur in 9% of summer checklists and 16% of winter checklists.
The Bald Eagle is a widely-recognized bird of prey. It has a white head, yellow eyes, and a large, hooked yellow bill. Its body is chocolate brown, and its legs are yellow, with huge talons.

You can find the Bald Eagle, during its breeding season, in wetland environments. Open and large bodies of water with plenty of fish are ideal spots.
Bald Eagles are opportunistic feeders and will eat what is available. Their favorite food is fish, and they prefer large ones, like trout and salmon, but also take birds and mammals. They may hunt these fish themselves or steal them away from other birds.
Bald Eagle Calls: The squeak of the Bald Eagle does not fit its size as they make a rather disappointing high-pitched whistle!
Fun Fact: The Bald Eagle has been the national symbol of America since 1782. It may be named “bald,” but it isn’t actually bald. The old version of “bald” actually meant “white,” referring to its white head and tail.
7. Golden Eagle
Golden Eagles are not very common in Maryland, but there have been sightings here during winter from September to April.
Golden Eagles are the most widely distributed eagles in the world. Their crown and nape (neck) are golden-brown and are a sight to behold when in the right light.
Their bodies are darker brown but with pale flight feathers. Their eyes vary from light yellow to dark brown and are ringed in yellow.
While adults look similar, females are larger than males. Juveniles are also similar, but they tend to have a darker color.
- Aquila chrysaetos
- Length: 27 – 38 in (69 – 97 cm)
- Weight: 160 oz (4534 g)
- Wingspan: 72 – 96 in (183 – 244 cm)
Golden Eagles that breed in Canada and Alaska migrate south for winter to the United States and northern Mexico. However, Golden Eagles in western US states remain all year.
You can find Golden Eagles in mountainous habitats far above the treelines. They also inhabit canyons, riverside cliffs, and bluffs when nesting. They generally prefer to avoid human presence.
Since Golden Eagles are birds of prey, naturally, they’d prey on small to medium-sized animals like rabbits, prairie dogs, and hares. On occasion, they may also hunt and take down larger prey like cranes, swans, and domestic livestock.
They usually hunt in pairs, with one chasing down the prey until it gets tired, and then the other swoops in for the kill.
Golden Eagle Call: The main calls that are made by Golden Eagles are during the breeding season when chicks are begging, and parents respond. Otherwise, they are pretty quiet. They make high-pitched whistled calls.
Fun Fact: The Golden Eagle, the Rough-legged Hawk, and the Ferruginous Hawk are the only American birds of prey that have feathers on their legs up to their toes.
8. Sandhill Crane

- Weight: 132.27 oz (3749 g)
- Wingspan: 73 – 90 in (185 – 229 cm)
Sandhill Cranes breed in Alaska, Canada, and northern and central US states before migrating to southern US states for winter.
You can find Sandhill Cranes during winter in shallow lakes, irrigated croplands, pastures, and grasslands. From spring to summer, they move to and stay in their breeding grounds in open wetland habitats with shrubs or trees.
Sandhill Cranes are omnivores and feed on both land and water. When on land, they eat seeds, grains, berries, and tubers. When on water, they will pluck out plants from the water, or probe through mud and vegetation for amphibians, reptiles, and small mammals with their long bills.
Sandhill Crane Calls:
Fun Facts: Sandhill Cranes find their mates by performing unison calling (loudest and most noticeable calls) and through dancing rituals. They are monogamous and mate for life.
9. Brown Pelican
Brown Pelicans have been spotted all year in Maryland, but they are most common in the south of the state from April to December.
Brown Pelicans are easy to identify with their large bills and throat pouches and brown bodies. They have white heads and necks with pale yellow foreheads. Their pale, long bills are part yellow, part orange and they have short, black legs and webbed feet.
Juveniles have brown heads, necks, backs, and wings and bluish-gray bills.
The differences between the Pacific and Atlantic Brown Pelicans are more obvious during the Breeding Their napes’ color turns from white to dark brown but Atlantic Brown Pelicans have olive-brown throat pouches, while Pacific Brown Pelicans have red skin on their throat pouches.

- Weight: 131.2 oz (3718 g)
- Wingspan: 78 – 84 in (198 – 213 cm)
Brown Pelicans either breed and migrate or are resident all year along the Pacific Coast and Atlantic Coasts of North America and down to northern South America.
You can find Brown Pelicans around shallow water environments. They live year-round in estuaries and coastal marine habitats. You can also see them in mangrove islets and on sandbars, breakwaters, and offshore rocks when they’re resting.
Brown Pelicans have a unique foraging ability that makes them stand out. They can dive into deep ocean water to capture their prey in their throat pouches. When they surface, water drains from their pouches, allowing them to swallow their catch immediately.
Brown Pelican calls: Adults are usually silent, except for the occasional grunt, but juveniles will squark to beg for food.
Fun Fact: Brown Pelicans incubate their eggs by covering them using their webbed feet but the pesticide DDT caused the thinning of the eggshells and led them to break from the weight. It took a huge conservation effort to re-establish the number of Brown Pelicans.
10. Great Cormorant
Great Cormorants are usually spotted in Maryland during winter, from November to January, but they are not very common here.
The Great Cormorant is a stocky bird with a blocky head, thick neck, and hooked bill. Adults are almost black everywhere except for their white throats and yellow skin around the bill. When breeding, adults have a white patch on their thighs and white neck feathers.

As a waterbird, its main food is fish which the Great Cormorant catches by diving and capturing it with its beak.
Great Cormorant call:
FUN FACT: The Great Cormorant can dive up to a depth of almost 6 meters and it’s possible that their hearing has evolved to enable them to better catch fish at this depth.
11. Great Blue Heron
Great Blue Herons are very common in Maryland and are spotted in the state all year. They are recorded in 22% of summer checklists and 15% of winter checklists submitted by bird watchers for the state.

Wood Storks remain all year around the Gulf Coast and southern Atlantic coast, but may move inland for breeding. They are also found in Central and South America.
You can find Wood Storks in open forested wetlands. During the breeding season, they prefer areas with a lot of trees, especially Taxodium trees, that are along a water’s edge. Water levels should be about four to twelve inches deep for them to forage successfully.
That is why swamps, ponds, marshes, and mangrove forests are ideal places to find them.
Wood Stork Calls:
Fun Fact: Wood Storks used to be called “wood ibis” because its head looks like an ibis. It has also been known as American Wood Stork because it is found in the Americas.
15. Great Horned Owl
Great Horned Owls do not migrate from Maryland but they are spotted more from September to March. They are recorded in 1% of winter checklists submitted by bird watchers for the state.
Great Horned Owls are one of the most common owls in North America.
Their most unique physical characteristic is their “Great Horns” which aren’t really horns but ear tufts. They’re tufts of feathers that they use as camouflage to make them appear like branches of trees.
The coloring and patterns of Great Horned Owls are also mainly for camouflage. Their backs and wings are mottled with gray, brown, black, or white.

Their varied diet includes small rodents such as mice, skunks, geese, and hares. They will also eat insects, fish, and carrion. They hunt from a perch, scanning their territory and swooping down to capture their prey with their strong talons.
Great Horned also hunt other raptors such as Ospreys, Peregrine falcons, or other owls.
Great Horned Owls: The distinctive 5-note Hoo call of the Great Horned Owl is made by both males and females, but females are higher pitched. They also make various whistles, shrieks, hisses, and coos.
Fun Fact: Great Horned Owls are the crows’ number one enemy. Crows will usually mob Great Horned Owls in their nests, and that is one of the best ways to find them.
16. Black Vulture
Black Vultures are residents of Maryland all year. They appear in 14% of summer and winter checklists.
Black Vultures are considered the blackest of all the vultures. Their backs, wings, breasts, bellies, and tails are black, although they have silvery patches on the underside of their wings that make it look like they have fingers when in flight.

Black Vultures eat practically anything, but mainly they eat carrion or decaying animals. They may be able to see dead animals on the ground themselves, but they usually rely on other scavenger birds to direct them towards food.
Black Vultures Calls: They do not make many sounds and instead have a deep ‘coo’ grunt.
Fun Fact: Black Vultures are “bald” out of necessity because it needs to stick its head into the bodies of dead animals to get to their juiciest parts. Having feathers on their heads will make it hard for them to clean themselves up when bits and pieces of the carrion stick to the feathers.
17. Great Black-backed Gull
Great Black-backed Gulls are spotted in Maryland all year but their numbers increase from October to March. They occur in 3% of summer checklists and 8% of winter checklists.

Turkey Vultures’ main source of food is carrion or recently dead or decaying animals as long as it hasn’t decayed too much. They may feed on roadkill and washed-up fish and may even kill small or weak animals.
Turkey Vultures calls: They can only make a raspy hissing sound, but are usually silent.
Fun Facts: When Turkey Vultures are threatened or aggravated, they will vomit to provide a distraction and fly away. They may even pretend to be dead.
21. Rough-legged Hawk
Rough-legged Hawks are not often spotted in Maryland but there have been some sightings in the state during winter, from October to mid-May.
The feathered legs of the Rough-legged Hawks give them their name and help to keep them warm in the arctic. They are fairly large hawks, between the size of a crow and a goose.
This predominantly dark-brown species occurs in light and dark forms, with dark patches at the bend of the wing, end of their tails, and across the belly. They have broad wings that are relatively long and narrow compared to other hawks.

They live all year in Eastern US states, across Canada, and into Northwestern US states.
You can find Pileated Woodpeckers in mature forests or drowned forests with lots of dead trees, but they also visit backyard feeders, especially for suet. They make distinctive rectangular holes in trees, so look out for these.
Pileated Woodpeckers mostly eat carpenter ants from dead trees and fallen logs, but they also eat beetle larvae, termites, and other insects as well as fruit and nuts such as blackberries, sumac berries, dogwood, and elderberry.
Pileated Woodpecker call and drumming:
Pileated Woodpeckers’ drum is loud and booming due to their size. They also make a ‘wuk-wuk-wuk’ call and one that sounds like laughing.
