Birds are known for their colorful plumage and feathered adornments, yet some species exhibit a distinctive lack of feathers.
In the animal kingdom, baldness is a rare trait, but a number of bird species have evolved partially or fully bare heads and necks.
This unusual adaptation likely serves important functions related to heat regulation, communication, and feeding behaviors. Let’s take a look at some of the most iconic bald bird species across the globe!
- Scientific Name: Meleagris gallopavo
- Length: 110-115 cm (43.3-45.3 in)
- Weight: 2,500-10,800 g (88.2-381.0 oz)
- Wingspan: 125-144 cm (49.2-56.7 in)
What they look like: Wild Turkeys are large birds with a distinctive appearance — almost any schoolchild in the US can recognize the Wild Turkey! They have long legs, wide, rounded tails, and a small bald head on a long, slim neck. Their plumage is dark overall with a bronze-green iridescence, and their wings are dark with white bars. The bare skin on the head and neck can vary in color, from red to blue to gray.
Where they live: Wild Turkeys are found in mature forests, particularly those with nut trees like oak, hickory, or beech, interspersed with open areas such as pastures, fields, and orchards. They can also be seen in woodsy backyards and along roads.
Interesting facts: Wild Turkeys are agile fliers despite their size. They forage on the ground, feeding on nuts, berries, insects, and snails. Males display during the breeding season by puffing up their feathers, spreading their tails into a fan, and gobbling. They are polygamous, mating with as many hens as possible.
- Scientific Name: Torgos tracheliotos
- Length: 95-115 cm (37-45 in)
- Weight: 4.4 to 9.4 kg (9.7 to 20.7 lb)
- Wingspan: 2.5-2.9 m (8.2-9.5 ft)
What they look like: The Lappet-faced Vulture is a massive bird and ranks as the longest and largest winged vulture in its range. It has mostly black plumage with contrasting white feathers on the thighs. The underside can range from pure white to buff brown. Like many vultures, it has a bald head, which can vary in color from reddish to pink on the back of the head and gray on the front. The head features fleshy folds on the sides.
Where they live: Lappet-faced Vultures have a patchy distribution through much of Africa and the Arabian Peninsula. They prefer to live in dry savannah, thornbush, arid plains, deserts with scattered trees in wadis, and open mountain slopes.
Interesting facts: Lappet-faced vultures are powerful and aggressive scavengers, often starting to tear through the skin of carcasses on their own. They are known for their ability to assert themselves over other vultures and access the tough hides and muscles of large mammals that others cannot penetrate.
- Scientific Name: Numida meleagris
- Length: 53-58 cm (21-23 in)
- Weight: Approximately 1.3 kg (2.9 lb)
What they look like: The Helmeted Guineafowl is a large bird with a round body. It has a gray-black plumage with white speckles. Its head is unfeathered and adorned with a dull yellow or reddish bony knob. The wings are short and rounded, and the tail is similarly short. There’s considerable variation in the appearance of different subspecies, particularly in the shape, size, and color of the casque, and the bird’s facial wattles.
Where they live: Helmeted Guineafowl thrive in warm, fairly dry, and open habitats with scattered shrubs and trees, such as savannas and farmland. They are widespread throughout much of Africa.
Interesting facts: This species is well-known for its tick-eating habit, which can help control tick populations and reduce the spread of tick-borne diseases. Helmeted Guineafowl are often domesticated and are found in various parts of the world, including the West Indies, North America, Australia, and Europe, due to their adaptability and usefulness.
- Scientific Name: Platalea ajaja
- Length: 71-86 cm (28-34 in)
- Weight: 1.2-1.8 kg (2.6-4.0 lb)
- Wingspan: 120-133 cm (47-52 in)
What they look like: The Roseate Spoonbill is a large, striking wading bird. Adults exhibit a distinctive deep pink plumage with a greenish head and white neck, back, and breast. During the breeding season, both males and females develop a tuft of pink feathers in the center of the breast. The bill, a defining feature, is long, grey, and spatula-shaped.
Where they live: Roseate Spoonbills can be found in both South and North America, including regions in Texas, Florida, southwest Louisiana, South America (east of the Andes), and coastal areas of the Caribbean, Central America, Mexico, and the Gulf Coast of the United States. They have also expanded their range, notably in Georgia and South Carolina. Their nesting sites include shrubs or trees, often mangroves.
Interesting facts: Their distinctive pink coloration is derived from the carotenoid pigment canthaxanthin, similar to the American flamingo. It doesn’t become vibrant until they are about 3 years old.
- Scientific Name: Leptoptilos crumenifer
- Length: Up to 152 cm
- Weight: 4.5-9 kg
- Wingspan: 3.7 m (maximum reported 4.06 m)
What they look like: The Marabou Stork is a massive bird with distinct features. It has a bare head and neck, a black back, and white underparts. The bird’s most notable features include a huge bill, a pink gular sac at its throat, a neck ruff, and white legs with black wings. Both males and females look similar, while young birds are browner and have smaller bills. Full maturity is reached at up to four years.
Where they live: Marabou Storks are native to sub-Saharan Africa. They can be found in various habitats, including wet and arid areas. They often live near human habitation, particularly landfill sites.
Interesting facts: Marabou Storks are often referred to as “undertaker birds” due to their distinctive appearance, resembling an undertaker’s attire when viewed from behind, with cloak-like wings and back, skinny white legs, and sometimes a large white mass of “hair.”

- Weight: Around 1.0–1.3 kg (35–46 ounces)
- Wingspan: Approximately 125–135 cm (49–53 inches)
What they look like: The Northern Bald Ibis is an attention-grabbing, glossy black bird known for its unique appearance. Its plumage is black, adorned with bronze-green and violet iridescence. A notable feature is the dull red, unfeathered face and head, accompanied by a long, curved red bill. Its legs are also red. In flight, it displays powerful and shallow wing beats, creating a distinctive profile.
Where they live: The Northern Bald Ibis is typically found in barren, semi-desert, or rocky habitats, often near running water. Although they were once found in the European Alps, Northern Africa, and the Middle East, today about 99% of Northern Bald Ibis are in Morocco.
Interesting facts: They were thought to be extinct until a small number of these birds were rediscovered in Syria in 2002. There were fewer than 10 left in Syria by 2019. Intentional breeding colonies have been established in Morocco, Spain, Italy, Austria, and Turkey. They are Endangered, but no longer considered Critically Endangered.
- Scientific Name: Perissocephalus tricolor
- Length: Approximately 40 centimeters (16 inches)
- Weight: Between 340 and 420 grams (12 and 15 ounces)
What they look like: The Capuchinbird is a large passerine bird with a heavy bill. It is mostly brown, although the belly and undertail are orangeish in color. They have a vulture-like bald head that is covered with blue skin. While they are young, they may have a few feathers on their head.
Where they live: Capuchinbirds are primarily found in humid forests in northeastern South America. They inhabit regions with elevations up to 1,400 meters (4,600 feet), although they are typically seen at altitudes below 600 meters. Their range is mostly situated north of the Amazon River and east of Rio Negro, covering areas in Colombia, Venezuela, Brazil, and The Guianas.
Interesting facts: Capuchinbirds are known to gather in leks where they produce a distinct vocalization. Describing their “song” is challenging, as it has been compared to the distant sound of a chainsaw or even the mooing of a young cow. This unique vocalization adds to the bird’s mystique and sets it apart from other bird species.
- Scientific Name: Trigonoceps occipitalis
- Length: 72–85 centimeters (28–33 inches)
- Weight: Females: 4.7 kilograms (10 pounds), Males: 4 kilograms (8.8 pounds) or less
- Wingspan: 207–230 centimeters (81–91 inches)
What they look like: The White-headed Vulture is a medium-sized Old World vulture with a pink beak and a white crest. Featherless areas on its head are pale, and it has dark brown upperparts with black tail feathers. However, its most recognizable characteristic is the strong contrast between the black upper parts and the white feathers on its lower parts and legs, making it easily distinguishable from other vulture species.
Where they live: White-headed Vultures are found throughout sub-Saharan Africa, with their range stretching from Senegal and The Gambia to Somalia in the east and South Africa and Eswatini in the south. Although they are locally uncommon to common, recent population estimates suggest a decline. They tend to avoid areas of human habitation and are often seen in protected regions, like the Kruger National Park in South Africa, which holds a significant population of the species.
Interesting facts: Interestingly, females are quite a bit larger than males. For most vultures, the opposite is true. Their diet mostly consists of carrion, but they will also prey on species like the slender mongoose, the monitor lizard, the tree squirrel, and the scrub hare.
- Scientific Name: Mycteria americana
- Length: 33–45 inches (83–115 cm)
- Weight: 5.5–7.3 pounds (2.5–3.3 kg)
