Grey-breasted Spurfowl

What Is the Grey-breasted Spurfowl?

The Grey-breasted Spurfowl (Pternistis rufopictus), also known as the Grey-breasted Francolin, is a species of gamebird in the family Phasianidae. It is endemic to Tanzania, meaning it is found nowhere else on Earth [citation:3][citation:12].

The species was formally described by the German ornithologist Anton Reichenow in 1887 under the name Pternistes rufopictus. The specific epithet is a combination of the Latin rufus for "red" and pictus for "painted", likely referencing the bird's reddish-brown markings [citation:3]. A molecular phylogenetic study published in 2019 found that the Grey-breasted Spurfowl is most closely related to the Red-necked Spurfowl (Pternistis afer) [citation:3].

The species is monotypic, meaning no subspecies are recognized [citation:3].

How to Identify a Grey-breasted Spurfowl

The Grey-breasted Spurfowl is a large-bodied francolin, but its plumage and vivid facial skin make it distinctive among Tanzania's gamebirds:

• Breast: The gray breast from which the species gets its name [citation:4].
• Underparts: The belly and flanks have chestnut, pale yellow and black markings, giving a scaly appearance [citation:9].
• Head & face: It has bare red skin on the throat and around the eyes, and a red bill [citation:4][citation:9].
• Legs: Dark grey legs [citation:9].
• Size: A body length of 32-41 cm [citation:4].
• Sexing: The male is much heavier (779-964 g) than the female (400-666 g), making it one of the few Tanzanian spurfowls with a significant size difference between the sexes [citation:4].

Distinguishing from Other Spurfowls

The Grey-breasted Spurfowl is most similar to the Red-necked Spurfowl. It can be distinguished by its grey (rather than red) breast and its narrower, less continuous red band on the throat. It is also smaller than the Hildebrandt's Spurfowl, which has a more prominent red throat and red legs [citation:3].

Behavior & Social Life

The Grey-breasted Spurfowl is a somewhat inconspicuous but charming bird, often heard before it is seen. It is most active in the early morning and late afternoon, when it comes out of cover to feed in the open [citation:4][citation:9].

Daily Activity

• Terrestrial: It is a ground-dwelling bird that prefers to run rather than fly when in danger, darting through the grass and shrubbery [citation:4].
• Roosting: During the hottest hours of the day, it will often rest in trees to escape the heat [citation:9].
• Group size: It is typically found alone, in pairs, or in small family groups [citation:4][citation:14].

Communication

Although no specific call is widely documented for this species, it is known to be a relatively quiet member of the spurfowl family. Its most common vocalization is a brief, raspy call at dawn and dusk [citation:3][citation:4].

Habitat & Distribution

The Grey-breasted Spurfowl is restricted to northwest Tanzania. Its range extends from the southeastern shore of Lake Victoria east to the Serengeti and Ngorongoro and south to the Wembere Plain in the Singida Region [citation:3][citation:4][citation:14].

Preferred Habitats

• Dry thorn scrub and grassland [citation:4].
• Acacia woodland and bushland [citation:4][citation:14].
• Grassland edges with scattered trees [citation:9].
• Farmland and riverine margins in the vicinity of its core savanna habitat [citation:4].

It seems to prefer areas receiving 500-700 mm of annual rainfall, which shapes its distribution across the Serengeti ecosystem [citation:4].

Type Locality

The type specimen for this species was collected in 1885 at Wembere Plain in the Singida Region of Tanzania, and the holotype is stored at the Museum für Naturkunde in Berlin [citation:2][citation:7].

Grey-breasted Spurfowl in Tanzania

The Grey-breasted Spurfowl is a genuine Tanzanian endemic and a sought-after species for birders visiting the northern circuit. Here are the best places to look for it:

Safari Methods

• Game drives through the savanna, especially in the early morning and late afternoon.
• Birdwatching focused on the Serengeti ecosystem's endemic species.
• Walking safaris where permitted, to flush them from scrub.
• Wildlife photography – their striking red face and grey breast make great subjects when they emerge from cover.

Best Time to See Them

Grey-breasted Spurfowl are present year-round in suitable habitat. They are most active during the cooler morning and evening hours, when they forage in open areas [citation:4][citation:9].

Diet & Feeding

The Grey-breasted Spurfowl is primarily a herbivore, but its diet is varied and adapted to the dry savanna environment [citation:4][citation:14].

Food Sources

• Sedge tubers and roots – especially of the genus Cyperus [citation:4][citation:9].
• Seeds of grasses and other plants [citation:4].
• Insects such as grasshoppers and termites [citation:4][citation:14].
• Small mollusks occasionally [citation:4].

Foraging Behavior

In the morning and evening, the bird forages on the ground, digging for tubers and scratching through leaf litter for seeds and insects [citation:4]. It is a relatively solitary forager, preferring to stay under cover [citation:9].

Breeding & Life Cycle

The Grey-breasted Spurfowl is a monogamous and territorial species. It breeds during the rainy season and the early dry season [citation:4].

Nesting

• Nest: A scrape in high grass, lined with grass and feathers [citation:4].
• Location: The nest is usually well-hidden in dense cover.
• Eggs: A clutch of 4-5 pale brown eggs [citation:4].

Incubation & Chicks

• Breeding season: February to April (late rains) and June to July (early dry season) [citation:4][citation:14].
• Precocial chicks: The chicks are precocial, leaving the nest soon after hatching and following the parents [citation:4].

Conservation Status

The Grey-breasted Spurfowl is assessed as Least Concern on the IUCN Red List [citation:1][citation:6][citation:8].

Its population is suspected to be stable. However, its status is significant because it is a Tanzanian endemic, meaning its entire global population is restricted to northwest Tanzania [citation:3][citation:12]. It is recorded from several Important Bird and Biodiversity Areas (IBAs/KBAs) across its range, which helps to protect its habitat [citation:15].

Despite its secure status, it faces some local pressures:

• Habitat loss and conversion of scrubland to agriculture.
• Hunting as a gamebird in some regions.
• Nest predation and local disturbance from grazing pressure.

The species is a key target for birding tourism in the Serengeti ecosystem, which provides an economic incentive for its conservation [citation:10][citation:15].
