About the Long-legged Buzzard
The Long-legged Buzzard, scientifically known as Buteo rufinus, holds a prominent position in the raptor family Accipitridae. This bird is often spotted across a vast range spanning from southeastern Europe and North Africa to central Asia. As a quintessential bird of prey, it thrives in open landscapes where it can efficiently hunt and thrive. Its presence is significant in ecosystems due to its role as a top predator, controlling populations of small mammals and other prey species. In regions such as the steppes of Kazakhstan and the semi-deserts of the Middle East, the Long-legged Buzzard is a critical component of the ecological balance. Its adaptability is evident in its ability to inhabit diverse environments, from the arid regions of the Sahara to the rolling grasslands of Ukraine. Seasonal behaviors of the Long-legged Buzzard include migration in some populations, especially those in the northern parts of its range that move southward in winter. These migrations underscore the bird's flexibility and resilience, traits that have allowed it to maintain stable populations despite environmental pressures. The Long-legged Buzzard's ecological role extends beyond predation; it also contributes to the scavenging community, cleaning up carcasses that might otherwise spread disease. Its presence in various habitats highlights its adaptability, making it a fascinating subject for ornithologists and bird watchers alike.
The Long-legged Buzzard belongs to the family Accipitridae, within the order Accipitriformes. These birds typically live average 15 years, with a maximum recorded of 22 years..
How to Identify a Long-legged Buzzard
Identifying the Long-legged Buzzard involves noting several distinct characteristics. Adults usually exhibit a strikingly broad wingspan, ranging from 122 to 145 cm, and their plumage varies from reddish-brown to a paler buff. The long legs, from which it derives its name, are especially noticeable when perched. Juveniles often display a more mottled appearance with a mix of lighter and darker feathers, which can lead to confusion with other Buteo species. Males and females are generally similar in appearance, although females tend to be slightly larger. In flight, the Long-legged Buzzard can be distinguished by its broad wings and relatively short tail, which contribute to its soaring flight pattern. Unlike the Common Buzzard, which has a more rounded wing shape, the Long-legged Buzzard's wings appear more angled. Perched, it holds a more upright posture, emphasizing its length. Observers can often differentiate it from similar species by focusing on these flight and perching characteristics.

Long-legged Buzzard Habitat and Range
Preferred Habitat
The Long-legged Buzzard primarily inhabits open and semi-open environments, such as grasslands, semi-deserts, and steppes. It is frequently found across elevations ranging from sea level to around 3,000 meters, depending on the region. In the Middle East, it often occupies arid desert margins, while in southern Europe, it prefers agricultural lands interspersed with patches of natural vegetation. During the breeding season, it may retreat to more elevated, rugged terrains, utilizing cliff faces and high perches for nesting and hunting. This raptor shows a degree of adaptability to human-modified landscapes, occasionally venturing into urban fringes, although it avoids densely populated areas. Seasonal shifts in habitat can occur, with some populations moving to lower elevations or more southerly locations during winter months.
Geographic Range
The Long-legged Buzzard's range is extensive, covering parts of southern Europe, North Africa, the Middle East, and central Asia. Its breeding range includes countries like Turkey, Iran, and parts of Russia, extending to the western reaches of China. In winter, some populations migrate to northern and eastern Africa, including countries such as Egypt and Sudan, as well as the southern Arabian Peninsula. Key migration corridors follow major river valleys and mountain ranges, providing the necessary thermal currents for their soaring flight. The bird's distribution is not uniform; it is more densely populated in regions like the steppes of Kazakhstan and less common in heavily forested areas. The Long-legged Buzzard's adaptability to a variety of open habitats allows it to maintain a widespread presence across its range.

What Does the Long-legged Buzzard Eat?
The diet of the Long-legged Buzzard primarily consists of small mammals, such as rodents and hares, which it captures with precision using its powerful talons. This raptor also preys on birds, reptiles, and large insects, depending on availability. Seasonal diet variations occur, with a greater reliance on insects and reptiles during warmer months. The Long-legged Buzzard employs a variety of foraging techniques, including soaring at moderate heights to spot prey and perching on high vantage points to ambush. It has been observed hunting in early morning and late afternoon, coinciding with peak activity times for many of its prey species. Prey size typically ranges from small rodents to medium-sized birds, highlighting its versatility as a predator.
Long-legged Buzzard Behavior and Social Structure
The Long-legged Buzzard exhibits solitary and territorial behaviors, particularly during the breeding season. Pairs engage in aerial displays to establish and defend territories, often involving dramatic, spiraling flights and vocalizations. Courtship displays are elaborate, with males showcasing aerial prowess to attract mates. While generally solitary, some non-breeding individuals may form loose flocks outside the breeding season, especially when migrating or during peak prey abundance. This raptor is diurnal, with peak activity occurring in the morning and late afternoon. When threatened by predators, such as larger raptors, it may engage in aggressive aerial confrontations to protect its territory. The Long-legged Buzzard's daily routine involves extensive soaring, scanning the terrain for prey, and perching for rest or ambush hunting.
Long-legged Buzzard Nesting and Reproduction
Long-legged Buzzards prefer to nest in elevated, open sites such as cliff ledges, isolated trees, or even man-made structures like power-line pylons. Nests are bulky constructions made of sticks, lined with softer materials like grass, feathers, and wool. Clutch sizes usually range from 2 to 4 eggs, with an incubation period of about 33 to 35 days. Both parents share the responsibility of incubation, though the female typically takes the lead. After hatching, the young remain in the nest for approximately 45 to 50 days before fledging. Parental roles are well-defined, with the male primarily hunting and the female attending the nest. In favorable conditions, Long-legged Buzzards may raise one brood per year, although this can vary based on food availability and environmental conditions.
Long-legged Buzzard Sounds and Vocalizations
The primary vocalization of the Long-legged Buzzard is a loud, plaintive call, often described as a series of high-pitched whistles or mewing sounds. These calls serve various purposes, such as territory defense and communication between mates. Alarm calls are sharper and more rapid, used to deter potential threats. During the dawn chorus, these buzzards may contribute their distinct calls to the avian symphony, though they are less vocal than many songbirds. The sound of the Long-legged Buzzard is reminiscent of a distant, drawn-out cry or a cat-like mewl, a distinctive trait among its raptor relatives.
