Crested Goshawk

About

The Crested Goshawk (Accipiter trivirgatus) is a medium-sized raptor found in tropical and subtropical Asia. It is characterized by its robust build, short, rounded wings, and long tail, typical of Accipiter species. Its distinctive crest, though often subtle, gives it its common name. It is an agile hunter of forest and woodland edges, preying on a variety of small to medium-sized vertebrates.

Size & lifespan

Length

30-46 cm

Wingspan

60-87 cm

Weight

220-450 g (male), 340-600 g (female)

Lifespan

Approximately 8-12 years in the wild

Diet

Carnivore (primarily birds, small mammals, reptiles, and large insects)

Physical characteristics

Plumage

Adults have a dark grey to brownish-grey back, head, and crest. The underparts are white with prominent rufous-brown barring on the breast and flanks, and a streaked throat. The tail is dark with 3-4 broad pale bands. The undertail coverts are white. The flight feathers are barred. Some subspecies may show more rufous tones.

Beak shape

Strong, hooked beak, dark grey to black with a yellow cere.

Eye color

Bright yellow to orange-yellow in adults, paler in juveniles.

Leg color

Yellow to orange-yellow.

Distinguishing features

Short, erectile crest (often difficult to see unless agitated), broad rufous-brown barring on underparts, streaked throat, and a relatively short, broad-winged silhouette in flight. The dark mesial stripe on the throat is also a good field mark.

Juvenile appearance

Juveniles have browner upperparts with pale feather edgings, giving a scaled appearance. Underparts are buffy white with heavy dark brown streaking on the breast and belly, often forming a 'tear-drop' pattern. The eyes are paler yellow. The crest may be less developed.

Seasonal changes

No significant seasonal plumage changes. Plumage remains consistent year-round after reaching adult coloration.

Sexual dimorphism

Females are noticeably larger and heavier than males, but plumage is similar. Males tend to be more richly colored on the underparts.

How to identify

1. 1

   Size and Shape

   Medium-sized Accipiter with relatively broad, rounded wings and a long tail. Appears robust. Females are significantly larger than males.

2. 2

   Plumage (Adult)

   Look for the dark grey upperparts, prominent rufous-brown barring on the white underparts (especially breast and flanks), and a streaked throat. The dark mesial stripe on the throat is a good indicator. Tail has broad pale bands.

3. 3

   Crest

   While often subtle, a short, erectile crest on the nape can be seen, especially when the bird is alert or agitated. This is a key feature for its common name.

4. 4

   Eye and Leg Color

   Bright yellow to orange-yellow eyes and yellow to orange-yellow legs are characteristic of adults.

5. 5

   Juvenile Plumage

   Young birds are browner above with pale feather edges and have heavy dark brown streaking (often tear-drop shaped) on buffy-white underparts. Eyes are paler yellow.

6. 6

   Flight

   Powerful, agile flight with rapid wing beats and glides. Often flies low through forest canopy or along edges. Soars with wings held in a slight dihedral.

7. 7

   Vocalizations

   Listen for its distinctive sharp, high-pitched 'ki-ki-ki-ki' or 'kew-kew-kew' calls, especially during the breeding season.

Habitat & range

Biomes

Tropical and subtropical forests, woodlands, forest edges, plantations, and sometimes suburban areas with mature trees.

Geographic range

South and Southeast Asia, from India and Sri Lanka eastward through Southeast Asia to southern China, Taiwan, and the Philippines. Specific distribution varies by subspecies.

Elevation range

Sea level up to approximately 2,000 meters (6,500 feet), occasionally higher.

Preferred environments

Prefers dense forest with clearings, often near water sources. Adaptable to fragmented forests and human-modified landscapes as long as suitable tree cover and prey are available.

Behavior

Activity time

Diurnal, most active during daylight hours.

Feeding habits

A stealthy hunter, often perching inconspicuously within the canopy or on a hidden branch, waiting to ambush prey. It makes short, powerful flights to capture birds, small mammals (like squirrels and bats), lizards, and large insects. It is known to hunt in pairs during the breeding season.

Social behavior

Generally solitary or found in pairs, especially during the breeding season. Not typically seen in large flocks.

Flight pattern

Characterized by rapid wing beats interspersed with glides. Soars less frequently than larger raptors. Agile and maneuverable, especially when hunting within dense forest. When soaring, it holds its wings in a slight dihedral.

Migration pattern

Mostly resident throughout its range, with some localized movements or altitudinal migration in certain areas, particularly in response to food availability or harsh weather.

Territoriality

Territorial, especially around nesting sites. Pairs will defend their breeding territory from other raptors.

Breeding & reproduction

Breeding season

Varies geographically, generally from February to June in most parts of its range, but can extend earlier or later depending on local conditions.

Nesting habits

Builds a stick nest, often lined with green leaves, in the fork of a tall tree, typically 6-20 meters (20-65 feet) above the ground. Both sexes participate in nest building.

Clutch size

2-4 eggs, usually 2-3.

Egg description

Typically 2-4 eggs, dull white or pale bluish-white, sometimes faintly marked with reddish-brown spots.

Incubation period

Approximately 30-35 days, primarily by the female.

Fledging period

Chicks fledge around 35-40 days after hatching, but remain dependent on parents for several weeks thereafter.

Parental care

Both parents care for the young. The female primarily incubates and broods, while the male provides most of the food during this period. Both parents feed the nestlings and fledglings.

Where to find

Field tips

1. Scan the Canopy. Look for it perched inconspicuously on a branch within the mid to upper canopy, often waiting for prey. Its cryptic plumage can make it hard to spot.
2. Listen for Calls. Its distinctive calls are often the first indication of its presence, especially during the breeding season. Learn to recognize its 'ki-ki-ki' call.
3. Observe Prey Activity. Where there are active populations of small birds, squirrels, or lizards, a Crested Goshawk might be hunting nearby.
4. Look for Movement. Watch for sudden, powerful flights through the undergrowth or across clearings as it pursues prey.
5. Check for Nesting Sites. During the breeding season, look for large stick nests in tall trees, often near the forest edge. Be respectful and maintain distance.

Fun facts

• The 'crest' from which it gets its name is often very subtle and can be difficult to observe in the field unless the bird is agitated or displaying.
• Like many Accipiters, the Crested Goshawk exhibits significant sexual dimorphism in size, with females being considerably larger than males, a common adaptation in raptors where the female defends the nest and the male hunts smaller, more agile prey.
• It is known for its stealthy hunting technique, often perching motionless for long periods before launching a swift, surprise attack on unsuspecting prey.
• Despite its widespread distribution, it can be a challenging bird to observe due to its preference for dense forest cover and its secretive nature.
