Physical Description

The adult Eastern Buzzard has dark brown upperparts and pale underparts. The head is paler in color compared to the rest of the body. It has a hooked yellow beak and fierce yellow eyes. The wings are broad and rounded, ideal for soaring across grasslands and forests in search of prey. The tail is long with a white tip. The legs and feet are yellow and equipped with sharp talons used for hunting and killing prey.

Distinguishing Features:

  • Broad, rounded wings
  • Yellow eyes and beak
  • Dark brown back and wings
  • Pale underparts
  • Long tail with white tip

Habits and Behavior

The Eastern Buzzard is a skillful and tactical hunter. It employs various techniques to hunt for small mammals, birds, reptiles and insects:

  • Perches on high vantage points to spot potential prey
  • Scans ground below with keen eyesight
  • Identifies prey and swoops down at high speeds to capture it
  • Uses sharp talons to grasp and kill prey
  • Sometimes soars in circles at low heights to surprise prey
  • Adapts hunting style based on available food sources

These buzzards are territorial and nesting pairs may use the same breeding sites annually. They are also known to be highly aerial and spend long periods soaring over their territory.

Breeding and Reproduction

The Eastern Buzzard breeds during spring and early summer. Breeding begins with courtship displays by the male, involving high soaring and loud calls to attract a female mate.

Once paired, the buzzards construct a large stick nest lined with leaves, grass and moss. The nest is built on a tree branch or cliff ledge.

The female lays 1-3 eggs which she incubates for 30-35 days while the male provides food. After hatching, both parents feed and care for the chicks.

The young fledge and leave the nest after 2-3 months but remain dependent on the parents for food and guidance for some time. They reach sexual maturity after 2-3 years.

Diet and Hunting

This bird of prey is a formidable hunter and feeds on a diverse range of prey:

  • Small mammals: mice, rats, squirrels
  • Small birds: sparrows, swifts, pigeons
  • Reptiles: snakes, lizards
  • Large insects: grasshoppers, cicadas

The Eastern Buzzard hunts by perching on an elevated vantage point like a tree branch or telephone pole. It scans the terrain below with its sharp vision, looking for signs of movement that give away potential prey.

Once prey is spotted, the buzzard sweeps down rapidly with its wings tucked in, talons extended forward to clutch the target animal. It uses its sharp talons and curved beak to kill and tear the prey into consumable pieces.

Habitat and Distribution

The Eastern Buzzard occupies various habitats across its range in Southeast Asia.

Favored habitats:

  • Forest edges and clearings
  • Open woodlands
  • Grasslands
  • Farmlands and agricultural areas
  • Coastal habitats

It can adapt well to human-altered environments as long as there are sufficient elevated perches and prey availability.

This species has a wide distribution across Southeast Asia:

  • Malaysia
  • Singapore
  • Indonesia
  • Philippines
  • Thailand
  • Myanmar
  • Vietnam
  • Laos
  • Northeast India

Within its range, the Eastern Buzzard may be resident all year-round or migratory depending on the population. Northern populations in China migrate south to wintering grounds in Southeast Asia.

Threats and Conservation

Although still relatively widespread, the Eastern Buzzard faces a number of threats across its range:

  • Habitat loss due to deforestation, urbanization and agricultural expansion
  • Poaching and illegal hunting for trade
  • Decline in prey species
  • Use of pesticides and toxins
  • Human disturbance of nesting sites

Conservation actions needed:

  • Protection of habitats and restoration of degraded areas
  • Enforcement of hunting regulations
  • Reducing use of dangerous pesticides
  • Increased public awareness and education
  • Monitoring populations and research into ecology

Conservation Status:

IUCN Red List: Least Concern

Significance and Appreciation

The Eastern Buzzard is a superb hunter that plays an important ecological role in controlling populations of small animals like rodents. It also contributes to seed dispersal through its diet.

For bird enthusiasts, this raptor provides an opportunity to observe graceful flight techniques as it masters the skies over grasslands and woodlands. Its fierce eyes and hooked beak give it a bold and majestic appearance.

This resilient and adaptable bird of prey reminds us of the magnificence of Southeast Asian biodiversity. Conserving the Eastern Buzzard and its habitat ensures future generations can continue to enjoy this iconic species.
