The Wattled Starling (Creatophora cinerea) is a striking and highly social bird native to eastern and southern Africa, known for its distinctive facial wattles and unique behaviors among African starlings. This medium-sized starling species thrives in grassland, open woodland, and cultivated areas, often forming large, noisy flocks that are a spectacular sight to birdwatchers and nature enthusiasts alike. Its intriguing adaptations, nomadic lifestyle, and unusual physical traits make the Wattled Starling a fascinating subject for study and observation.
Scientific Classification
The Wattled Starling belongs to the family Sturnidae, which encompasses the diverse group of starlings and mynas. Its scientific name is Creatophora cinerea, and it is the only species within the genus Creatophora, making it monotypic. This uniqueness points to its distinct evolutionary lineage compared to other African starlings. While most African starlings belong to genera like Lamprotornis or Spreo, the Wattled Starling exhibits several morphological and behavioral traits that align it more closely with Asian starlings of the genus Sturnus, especially in terms of its bare facial skin and certain feeding habits.
First described by the French ornithologist Louis Jean Pierre Vieillot in 1817, the genus name Creatophora derives from Greek roots meaning “wattle bearer,” a clear reference to the bird’s distinctive throat wattles. The species epithet cinerea means “ashen” or “grey,” a nod to its primarily grey plumage. This combination of physical and behavioral traits distinctly separates the Wattled Starling from other members of its family.
Geographic Range & Distribution
The Wattled Starling is primarily found in eastern and southern Africa, with its range extending across countries such as Ethiopia, Kenya, Tanzania, Mozambique, Zimbabwe, Botswana, Namibia, and South Africa. It typically inhabits savannas, open grasslands, and agricultural lands, favoring areas with short vegetation and scattered trees or bushes. Its adaptability to human-altered landscapes has allowed it to thrive even in cultivated areas, where it often benefits from the abundance of insects stirred up by farming activities.
Interestingly, this species is known for its nomadic and irruptive behavior, often moving in response to the availability of food, particularly insect outbreaks like locust swarms. This mobility sometimes leads Wattled Starlings to extend their range temporarily into West Africa, Madagascar, the Seychelles, and even parts of the Arabian Peninsula. These excursions outside the core range are usually linked to ecological conditions such as seasonal rains or insect plagues, which create abundant feeding opportunities.
Outside the breeding season, Wattled Starlings may gather in enormous flocks, sometimes numbering in the tens of thousands, especially in wetlands and reedbeds that serve as communal roosting sites. These large gatherings are a spectacular spectacle and an important aspect of their ecology.
Physical Description
The Wattled Starling measures approximately 21 centimeters (about 8.3 inches) in length, with a wingspan ranging between 35 and 38 centimeters. It is a medium-sized starling with a compact body, short tail, and pointed wings that aid in agile flight. The bird weighs an average of 60 to 80 grams, placing it comfortably in the mid-range size for starling species.
Its plumage is predominantly ashy grey, which provides camouflage in its typical grassland and woodland habitats. The rump is pure white, contrasting sharply with the black flight feathers and tail, a distinctive feature that makes the species unmistakable in flight. The white rump is especially visible during flight displays and quick maneuvers.
Sexual dimorphism is evident, particularly during the breeding season. Breeding males develop prominent yellow, unfeathered patches of skin on their faces, including wattles on the forehead and throat that are black and fleshy. These wattles become more pronounced with age and breeding condition, forming a striking facial pattern that is unique among African starlings. Additionally, breeding males sport a striking white shoulder patch against their grey plumage. Females and juveniles lack the wattles and have duller coloration, with brown flight feathers and tail, helping them blend into the environment.
Outside the breeding season, males resemble females but retain a small yellow patch behind the eye and a faint black moustachial stripe. The white shoulder patch is reduced or absent. The bare patches of skin and wattles are important visual signals in social and breeding contexts.
Behavior & Diet
The Wattled Starling is a highly social and gregarious bird, often seen in large flocks that can include thousands of individuals. These flocks frequently mix with other starling species, such as the Cape Starling and Pied Starling, especially when roosting or foraging. Their social behavior extends to communal roosting in reedbeds and tall grasses, where they gather at dusk to rest safely overnight.
One of the Wattled Starling’s most remarkable behaviors is its feeding strategy. Unlike many African starlings that forage mainly on the ground or in trees, the Wattled Starling is adept at “open-bill” feeding – inserting its slightly open bill into soil or grass tufts to extract insects and larvae. This technique is more commonly observed in Asian starlings, highlighting the unique ecological niche this species occupies in Africa. Their diet is omnivorous, consisting predominantly of insects such as grasshoppers, locusts, beetles, caterpillars, and ants, which they often catch on the wing or glean from vegetation. According to eBird, this species is well documented.
Besides insects, these starlings also consume a variety of seeds, berries, and small fruits, particularly during the dry season when insects are scarce. This dietary flexibility allows them to survive in varied habitats and fluctuating environmental conditions. Their keen eyesight and quick reflexes make them efficient hunters, and they often follow large herbivores or agricultural machinery to catch insects disturbed by movement. According to Audubon Society, this species is well documented.
Breeding & Reproduction
The Wattled Starling is a colonial breeder, often nesting in loose colonies that may include several hundred pairs. Their breeding activity closely follows the abundance of insect prey, especially locust swarms, which provide the high protein resources needed to raise chicks successfully. When food is plentiful, colonies flourish, but if insect populations crash or are destroyed by control measures, birds may abandon nests mid-cycle, demonstrating their strong reliance on prey availability.
Breeding colonies are typically established in trees or large bushes, with acacias and eucalyptus frequently chosen as nesting sites. Nests are globular structures made from twigs and lined with grass or feathers, built at heights ranging from one to ten meters above the ground. Both males and females participate actively in nest construction, incubation, and chick feeding, exemplifying strong pair bonds and cooperative breeding behavior.
Clutches usually contain two to five eggs, with three or four being most common. Eggs are pale blue and may be immaculate or speckled with light brown spots. Incubation lasts approximately 11 days, after which the altricial chicks hatch and remain in the nest for 13 to 16 days before fledging. Despite parental care, young starlings are vulnerable to predation by large birds of prey such as hawks and falcons, which frequent the same habitats.
Conservation Status
The International Union for Conservation of Nature (IUCN) currently lists the Wattled Starling as a species of Least Concern, reflecting its wide distribution and stable population trends. It is a common and adaptable bird, able to exploit a range of habitats including those altered by human activities. However, its nomadic lifestyle means local populations can fluctuate dramatically in response to environmental conditions and insect availability.
Potential threats include habitat loss through agricultural intensification and pesticide use, which can reduce insect prey abundance. Additionally, widespread locust control operations, while necessary for protecting crops, can inadvertently impact breeding success by eliminating essential food sources. Despite these challenges, the Wattled Starling’s flexibility and wide range help buffer it from significant conservation risks at present.
Interesting Facts
One of the most visually captivating features of the Wattled Starling is its facial wattles, which are rare among African birds. These fleshy, brightly colored patches are used in social signaling during the breeding season and may help in mate selection. The extent and brightness of wattles increase with age and breeding condition, making them an honest indicator of fitness.
The species is also known for its complex vocalizations, which include a variety of wheezing, grating, and chattering calls. These sounds are reminiscent of the Common Starling (Sturnus vulgaris) of Europe, though the Wattled Starling’s vocal repertoire is tailored to its social and environmental contexts.
Another fascinating behavior is their communal roosting habit. At dusk, vast flocks gather in reedbeds or dense vegetation, creating a cacophony of calls and a swirling mass of birds that can be an unforgettable spectacle for observers. These roosts provide safety in numbers from nocturnal predators and facilitate social interactions within the flock.
Finally, the Wattled Starling’s close association with insect outbreaks, particularly locusts, makes it an important natural control agent. By feeding heavily on these pests, it contributes to regulating insect populations that can otherwise cause devastating damage to crops and natural vegetation.
Conclusion
The Wattled Starling (Creatophora cinerea) is a remarkable bird of the African grasslands and open woodlands, distinguished by its striking facial wattles, social nature, and adaptable feeding strategies. Its nomadic lifestyle, intricate breeding behaviors, and impressive flocking habits make it a captivating species for birdwatchers and researchers alike. While currently secure in its conservation status, the Wattled Starling’s dependence on insect populations highlights the delicate balance between wildlife and human agricultural practices. Observing this starling in its natural habitat offers a vivid glimpse into the dynamic ecosystems of Africa’s open landscapes and underscores the importance of conserving these environments for future generations.
