Vulturine Guineafowl
Acryllium vulturinumThe largest, most spectacular guineafowl – known as Kicheleko or Kororo tumbusi in Swahili.
The Vulturine Guineafowl (Acryllium vulturinum) is the largest extant species of guineafowl [citation:11]. It is easily distinguished from other guineafowl by its long, glossy, blue-and-white hackles that project from the neck, a cobalt-blue breast, and a bare blue face that gives it a vulture-like appearance [citation:1][citation:6][citation:11]. It is a resident breeder in northeast Africa, from southern Ethiopia through Kenya and just into northern Tanzania [citation:1][citation:11].
Vulturine Guineafowl Quick Facts
What Is the Vulturine Guineafowl?
The Vulturine Guineafowl (Acryllium vulturinum) is the largest extant species of guineafowl and the most spectacularly coloured of the family [citation:1][citation:11]. Systematically, it is only distantly related to other guineafowl genera; its closest living relative is the White-breasted Guineafowl (Agelastes meleagrides) of Central Africa [citation:11].
It is the only member of the genus Acryllium and a resident breeder in northeast Africa, from southern Ethiopia through Kenya and just into northern Tanzania [citation:1][citation:11]. The species gets its name from its small, bare head and long bare neck that resemble those of a vulture [citation:1][citation:11].
In Tanzania and Kenya it is known by its Swahili names Kicheleko or Kororo tumbusi [citation:3]. It is a bird of dry acacia scrubland and semi-arid savanna, often seen in flocks of 20-30 individuals [citation:3].
How to Identify a Vulturine Guineafowl
This species is unmistakable once seen. Its combination of brilliant colors and distinctive shape sets it apart from any other bird:
- Size: A large (61–71 cm) bird with a round body and small head [citation:1][citation:11].
- Neck and head: The adult has a bare blue face and black neck. It has a longer neck, legs, and tail than other guineafowl [citation:1][citation:11].
- Hackles: The slim neck projects from a cape of long, glossy, blue and white hackles (elongated neck feathers) [citation:1][citation:6][citation:11].
- Breast: A striking cobalt blue breast [citation:1][citation:11].
- Body plumage: Black, finely spangled with white [citation:1][citation:11].
- Wings: Short and rounded, with the tail being longer than others in the family Numididae [citation:11].
- Sexes: Similar in appearance, although the female is usually slightly smaller than the male and has smaller tarsal spurs [citation:1][citation:11].
Compared to Other Guineafowl
Unlike the Helmeted Guineafowl, which has a bony casque on its head, the Vulturine has a bare blue face with no helmet. The Vulturine is also slimmer and taller than other guineafowl species, with an unmistakable cobalt-blue breast [citation:1][citation:11].
Behavior & Social Life
The Vulturine Guineafowl is a gregarious species, forming flocks outside the breeding season typically of about 25 birds [citation:1][citation:3][citation:11].
Daily Activity
- Terrestrial: They spend the day scratching the ground in search of food [citation:3][citation:6].
- Flight: They prefer to run rather than fly when alarmed, but are strong fliers when they take to the air [citation:3][citation:6][citation:11].
- Roosting: At night they roost in trees, often flying up to their roosts [citation:1][citation:3][citation:6].
- Habitat preference: Despite the open habitat, they tend to keep to cover [citation:1][citation:11].
Communication
- Main call: A loud, high-pitched chink-chink-chink-chink-chink [citation:1][citation:11].
- Alternative call: A high-pitched, sing-song wi-yi-why-yi-why-yi-wii [citation:3].
- Disturbed: When excited or disturbed, their calls can be heard over long distances [citation:8].
They are capable of going for long periods without water, though they will drink when water is available [citation:3][citation:6].
Habitat & Distribution
The Vulturine Guineafowl inhabits dry and open habitats with scattered bushes and trees, such as savanna or grassland [citation:1][citation:11]. It is common in acacia scrubland and dry bush from southern Ethiopia and Somalia to Kenya and Tanzania [citation:3].
Distribution: It is a resident breeder in northeast Africa, from southern Ethiopia through Kenya and just into northern Tanzania [citation:1][citation:11].
Altitude: It lives in dry bush and savanna from sea level up to approximately 3,940 feet (1,200 m) [citation:3]. It is also recorded up to 1,900 m in some parts of its range [citation:5].
Tanzania Distribution
In Tanzania, the Vulturine Guineafowl is found in the dry north, primarily in Mkomazi National Park near the Kenyan border, which shares an ecosystem with Kenya's Tsavo West [citation:2]. A specimen has also been recorded from the North Pare Mountains in Tanzania [citation:7].

Thrives in arid thorn-scrub and semi-desert, often at the edges of lowland forest [citation:8].
Safari Methods
- Game drives through dry bushland and acacia scrub.
- Walking safaris where permitted, to watch them forage.
- Birdwatching – they are active and easy to observe in open habitats.
- Wildlife photography – their cobalt blue breast and long hackles make stunning subjects.
Best Time to See Them
Vulturine Guineafowl are present year-round in suitable habitat. They are most active during the cooler morning and evening hours, when they come out to forage in open areas.
Diet & Feeding
Vulturine Guineafowl are omnivorous, feeding on a wide variety of foods [citation:3][citation:8].
Food Sources
- Seeds and fallen fruit [citation:3].
- Insects – including grasshoppers and termites [citation:3].
- Tubers and roots [citation:3][citation:8].
- Small reptiles and rodents – they are quick enough to nab a small snake or rodent [citation:3][citation:8].
- Grubs [citation:8].
- Vegetation occasionally [citation:8].
Foraging Behavior
They spend the day scratching the ground in search of food [citation:3][citation:6]. They can go for long periods without water, though they will drink when water is available [citation:3][citation:6].
Breeding & Life Cycle
Breeding begins as the rainy season starts [citation:3].
Nesting
- Nest: A ground scrape made by the female, lined with grass or placed under low shrubs [citation:3][citation:8].
- Location: The nest is often situated under dense tussocks of grass or protected by rock or bush [citation:8].
- Eggs: Females lay 4-15 cream-colored or creamy-white eggs [citation:1][citation:8][citation:11].
Incubation & Chicks
- Incubation: Approximately 28 days [citation:3][citation:8].
- Chicks: Precocial – they leave the nest almost immediately and can feed themselves, but parents guide and protect them for some time [citation:8].
- Fledging: They can fly about 15-20 days after hatching, or by about 10 weeks [citation:3][citation:8].
Sexual Maturity
Birds attain their adult plumage at about six months and are sexually mature at two years [citation:15].
Conservation Status
The Vulturine Guineafowl is assessed as Least Concern on the IUCN Red List [citation:5][citation:10].
Its population is suspected to be stable, and it has an extremely large range of approximately 1,500,000 km² [citation:5][citation:10]. The total population may exceed 1 million individuals and is generally common and stable, though in some regions it may be locally reduced by overhunting [citation:14].
Despite its secure status, it faces some local pressures:
- Overhunting in some parts of its range [citation:14].
- Habitat loss and fragmentation.
- Trade – the species has been reported as used in trade at a high prevalence in some regions [citation:5].
No specific conservation actions are currently in place for this species, though it is recorded from 28 Important Bird and Biodiversity Areas (IBAs/KBAs) across its range [citation:5].
