Stork-billed Kingfisher

About

The Stork-billed Kingfisher is a large, striking kingfisher species known for its massive, bright red bill and vibrant plumage. It is a resident breeder across a wide range of tropical Asia, typically found near large bodies of water in forested or mangrove habitats. Its diet primarily consists of fish, crustaceans, and large insects, which it catches by diving from a perch.

Size & lifespan

Length

35-38 cm

Wingspan

48-52 cm

Weight

140-250 g

Lifespan

Approximately 5-10 years in the wild

Diet

Carnivore (primarily piscivorous, also crustaceans, large insects, small reptiles, and amphibians)

Physical characteristics

Plumage

Adults have a bright rufous (orange-brown) head and underparts, a greenish-blue back and wings, and a bright blue rump and tail. The throat is typically paler, often whitish. The flight feathers are dark with blue edgings.

Beak shape

Massive, long, and very stout, bright red to reddish-orange with a darker tip. The bill is disproportionately large compared to its head, giving it its 'stork-billed' name.

Eye color

Dark brown

Leg color

Bright red to reddish-orange

Distinguishing features

The combination of its enormous, bright red bill, rufous head and underparts, and blue-green upperparts is unmistakable. Its large size also sets it apart from most other kingfishers in its range.

Juvenile appearance

Juveniles resemble adults but have duller plumage, often with dusky scaling on the rufous parts, and a duller, more brownish-red bill.

Seasonal changes

No significant seasonal plumage changes.

Sexual dimorphism

Males and females are generally monomorphic in plumage. Females may be slightly larger on average, but this is not a reliable field mark.

How to identify

1. 1

   Bill

   Look for the exceptionally large, bright red to reddish-orange bill. This is its most distinctive feature.

2. 2

   Plumage Coloration

   Observe the combination of rufous (orange-brown) head and underparts with a contrasting greenish-blue back and wings, and a bright blue rump.

3. 3

   Size

   Note its large size for a kingfisher, making it stand out from smaller species.

4. 4

   Habitat

   Check for its presence near large, slow-moving water bodies in forested or mangrove areas.

5. 5

   Vocalizations

   Listen for its loud, harsh 'kreek-kreek-kreek' calls.

Habitat & range

Biomes

Tropical and subtropical moist broadleaf forests, mangroves, freshwater wetlands, coastal areas.

Geographic range

Indian subcontinent and Southeast Asia, from India and Sri Lanka east through Bangladesh, Myanmar, Thailand, Malaysia, Singapore, Indonesia (Sumatra, Borneo, Java, Sulawesi), and the Philippines.

Elevation range

Primarily lowlands, typically from sea level up to 1,000 meters, occasionally higher.

Preferred environments

Found along slow-moving rivers, streams, canals, lakes, ponds, estuaries, and coastal mangroves. Requires clear water for hunting and perches (trees, branches) overlooking the water.

Behavior

Activity time

Diurnal.

Feeding habits

A 'perch-and-plunge' hunter. It sits motionless on a prominent perch overlooking the water, then dives headfirst to catch fish, crustaceans, or other prey. It may also take prey from the water surface or from vegetation. Larger prey is often battered against the perch before consumption.

Social behavior

Generally solitary or found in pairs. Highly territorial, especially during the breeding season.

Flight pattern

Strong, direct flight with rapid wing beats, often low over the water. Can appear somewhat heavy in flight due to its large size.

Migration pattern

Resident throughout its range, not migratory.

Territoriality

Highly territorial, defending its feeding and nesting areas from conspecifics and other predatory birds.

Breeding & reproduction

Breeding season

Varies geographically, typically March-June in India, April-July in Southeast Asia.

Nesting habits

Nests in a tunnel excavated into an earthen bank, usually near water. The tunnel can be quite long (up to 1-2 meters) and ends in an unlined nesting chamber. Both parents participate in excavation.

Clutch size

2-5 eggs

Egg description

2-5 (typically 3-4) glossy white, spherical eggs.

Incubation period

Approximately 19-21 days, incubated by both parents.

Fledging period

Chicks fledge around 27-35 days after hatching. Both parents feed the young.

Parental care

Both male and female share incubation duties and feed the nestlings and fledglings.

Where to find

Field tips

1. Look for Perches. Stork-billed Kingfishers often sit motionless on prominent, often exposed, perches overlooking the water, such as dead branches, snags, or power lines. Scan these areas carefully.
2. Listen for Calls. Their loud, harsh calls can often betray their presence before they are seen. Learn to recognize their distinctive vocalizations.
3. Be Patient. They can be quite shy and wary. Patience is key, as they may remain still for long periods before diving or moving.
4. Early Morning/Late Afternoon. Activity is often higher during the cooler parts of the day, early morning and late afternoon.
