About the Augur Buzzard
The Augur Buzzard (Buteo augur) is a formidable bird of prey belonging to the Accipitridae family. This species is renowned for its striking plumage, which exhibits a bold contrast between the black upperparts and white underparts, accented by a rich red tail. Native to sub-Saharan Africa, the Augur Buzzard can be found in a variety of open habitats such as grasslands, savannas, and mountainous regions. It is especially prevalent in the highlands of East Africa, including countries like Kenya, Tanzania, and Uganda. The Augur Buzzard plays a crucial role in its ecosystem by controlling the populations of small mammals and birds, thus maintaining ecological balance. Its presence is a testament to the health of its habitat.
Significantly, the Augur Buzzard adapts well to seasonal changes, modifying its hunting strategies and diet according to prey availability. During the dry season, when small mammals become scarce, it shifts to preying on reptiles and birds. This adaptability highlights the bird's ecological importance and resilience. The Augur Buzzard is often seen perched atop trees or telephone poles, scanning the surroundings with its keen eyesight for potential prey.
The Augur Buzzard's ecological role extends beyond predation. It also acts as an indicator species, signaling the health of its environment. Changes in its population can reflect shifts in habitat quality, prey abundance, and broader environmental changes. Conservationists monitor this species to assess ecosystem health. Despite its adaptability, the Augur Buzzard faces threats from habitat loss and degradation, underscoring the importance of preserving its natural environments.
The Augur Buzzard belongs to the family Accipitridae, within the order Accipitriformes. These birds typically live average 12 years with a maximum recorded of 20 years..
How to Identify a Augur Buzzard
The Augur Buzzard is easily recognized by its contrasting black and white plumage. Adults display striking black upperparts, head, and breast, juxtaposed against white underparts and a vivid red tail, which is particularly noticeable in flight. The eyes are dark brown, and the legs and cere are yellow. Juveniles, in contrast, exhibit more muted tones with brown and buff mottling, lacking the distinctive red tail, which develops as they mature.
Although male and female Augur Buzzards appear similar, females are generally larger. This size difference can be subtle but is consistent with the sexual dimorphism seen in many raptor species. The bird's silhouette in flight is characterized by broad, rounded wings and a short, fan-shaped tail, which aids in identification even from a distance. When perched, the Augur Buzzard often adopts a hunched posture, with its head held low and wings tucked tightly against its body.
The Augur Buzzard could be confused with the Jackal Buzzard due to similar coloration. However, the Jackal Buzzard has more extensive black plumage on the belly and a differently colored tail. Observers can distinguish the Augur Buzzard by its more pronounced white underparts and the distinctive red tail, which remains a key field mark.

Augur Buzzard Habitat and Range
Preferred Habitat
The Augur Buzzard thrives in a range of open habitats, from grasslands and savannas to mountainous regions. It prefers elevations between 1,000 and 4,500 meters, favoring highland areas with scattered trees or rocky outcrops. Notably, it inhabits the Rift Valley and the Ethiopian Highlands, where it finds ample hunting grounds.
While primarily a bird of rural landscapes, the Augur Buzzard occasionally ventures into the outskirts of urban areas, especially where these abut natural habitats. Seasonal habitat shifts are minimal, as the bird is generally resident year-round, though it might move locally in response to food availability.
Unlike some raptors, the Augur Buzzard does not frequent dense forests or arid deserts. Instead, it relies on open areas where it can efficiently spot and pursue prey. The presence of tall perches such as trees or man-made structures facilitates its hunting strategy, making these features an essential component of its habitat.
Geographic Range
The Augur Buzzard's range is predominantly confined to sub-Saharan Africa, with a stronghold in the highland regions. It breeds across a vast area, from Ethiopia in the northeast to Angola in the southwest, encompassing countries like Kenya, Tanzania, and Uganda. This distribution highlights its preference for elevated terrains and diverse open habitats.
During the breeding season, the Augur Buzzard remains territorial, nesting in suitable locations within its established range. Unlike migratory raptors, it does not undertake long-distance migrations, although some local movements may occur in response to food scarcity or environmental changes.
The species is widely distributed but can be locally abundant in ideal habitats, such as the Ethiopian Highlands and the Great Rift Valley. These regions, with their mix of grasslands and scattered woodlands, offer optimal conditions for nesting and hunting. Population densities are often highest where prey is plentiful, and suitable nesting sites are available.

What Does the Augur Buzzard Eat?
The Augur Buzzard's diet primarily consists of small mammals, such as rodents and hares, which it captures using its sharp talons and keen eyesight. It also preys on birds, reptiles, and insects, showcasing its opportunistic feeding habits. Seasonal changes significantly influence its diet. During the breeding season, when small mammals are abundant, these creatures form the bulk of its diet.
In the dry season, the Augur Buzzard adapts by targeting reptiles like lizards and snakes, which become more active and visible. This dietary flexibility ensures the bird's survival across varying environmental conditions. The Augur Buzzard typically hunts from a perched position, watching for movement before swooping down to capture its prey.
Its foraging technique involves soaring high with a characteristic flight pattern, scanning the ground below for unsuspecting prey. The bird often hunts in the early morning and late afternoon, capitalizing on the cooler temperatures and increased prey activity during these times. Prey size varies, but the Augur Buzzard can tackle animals up to half its own weight, demonstrating its formidable hunting prowess.
Augur Buzzard Behavior and Social Structure
The Augur Buzzard exhibits solitary behavior outside of the breeding season, fiercely defending its territory from intruders. It patrols its domain with keen vigilance, often engaging in aerial displays to assert dominance and deter rivals. Mated pairs remain monogamous, using a combination of vocalizations and displays to reinforce pair bonds.
Courtship involves elaborate aerial displays, with the male performing dives and loops to impress the female. These displays often culminate in mutual soaring flights, where the pair locks talons in mid-air, a behavior known as 'sky dancing.' The Augur Buzzard's territorial instincts extend to its nesting grounds, where it aggressively defends against potential predators and rival raptors.
While primarily solitary, the Augur Buzzard occasionally congregates in loose groups during migrations or in areas with abundant prey. It shows a distinct daily pattern, being most active during the cooler parts of the day, resting during the midday heat. In response to predators, the Augur Buzzard emits loud alarm calls to alert its mate and, if necessary, confronts the threat directly. Its agile flight and hunting prowess make it a dominant presence in its habitat.
Augur Buzzard Nesting and Reproduction
The Augur Buzzard constructs its nest in high, inaccessible locations, often choosing tall trees or cliff ledges. The nest, a large platform of sticks lined with softer materials like leaves and grass, provides a secure site for raising young. Both members of the pair participate in nest building and maintenance, strengthening their bond through this cooperative effort.
The female typically lays a clutch of 1 to 2 eggs, which she incubates for approximately 34 to 36 days. During this period, the male supplies food, demonstrating the pair's division of labor. Once the chicks hatch, they remain in the nest for about 45 to 55 days, receiving food and protection from both parents.
Parental roles are well-defined, with the female primarily responsible for brooding the young, while the male focuses on hunting. The Augur Buzzard usually raises a single brood per year, although in areas with abundant resources, it may attempt a second. Fledging occurs when the young birds are ready to leave the nest, but they continue to rely on parental support for several weeks as they hone their flying and hunting skills.
Augur Buzzard Sounds and Vocalizations
The Augur Buzzard's primary call is a loud, piercing 'kee-yaah,' which resonates across its territory. This call carries a clear, ringing quality, often repeated in a series to assert dominance or communicate with a mate. The rhythm is distinctive, with a rising and falling pitch that echoes through the open landscapes it inhabits.
In addition to its primary call, the Augur Buzzard emits a range of sounds, including sharp alarm calls when threatened. These are shorter and more abrupt, serving to warn off intruders or alert a mate to danger.
During courtship, the pair engages in vocal duets, blending calls that strengthen their bond and synchronize their activities. The Augur Buzzard's vocalizations are most pronounced during the dawn hours, as it announces its presence and claims its territory. These vocal displays serve not only as communication but also as a key element in maintaining its social structure.
