The scimitar babbler is a species of bird found in tropical southern Asia. Despite its common name, it is not closely related to true babblers. Instead, it belongs to the family Timaliidae, along with many other babbler-like species found in Asia.
What does a scimitar babbler look like?
The scimitar babbler is a distinctive-looking bird, named for its strongly downcurved bill which resembles a Persian scimitar sword. They are medium-sized songbirds, measuring 18-21 cm long and weighing 30-55 grams.
Plumage is olive-brown above with a grayish breast and whitish belly. The head pattern is bold, with a black crown and nape, white supercilium and throat, and rusty ear coverts. The bill and legs are pinkish-red. Males and females look identical.
Juveniles have a duller version of the adult plumage, with a gray-brown crown and breast band. The bill starts out dusky gray and turns pink as the bird matures.
Where does the scimitar babbler live?
Scimitar babblers are found in tropical southern Asia, from eastern Nepal and northeast India through southeast Asia. Their range includes Bangladesh, Bhutan, Cambodia, India, Laos, Malaysia, Myanmar, Nepal, Thailand, and Vietnam.
They inhabit forests, secondary growth, bamboo thickets, and scrublands up to 1800 meters above sea level. However, they prefer dry deciduous forest and dense scrub along forest edges.
What is the scimitar babbler’s behavior like?
Scimitar babblers are social, active, noisy birds that travel in small groups of 6 to 10 individuals. They constantly make chattering, squeaking, whistling calls as they hop between branches and forage on the ground. Groups communicate with melodious duetting vocalizations that sound like high pitched whistles.
They have a communal breeding system where several females lay eggs in the same nest and share parenting duties. Nests are cup-shaped, made of grass and bamboo leaves and placed in dense bushes or bamboo clumps.
Scimitar babblers are omnivorous, feeding on insects, spiders, berries and seeds. They use their specialized bills to probe crevices and dig in the soil for food.

Here is a map showing their distribution:
What do they eat?
Scimitar babblers are omnivorous, eating a variety of foods including:
- Insects and spiders
- Berries
- Seeds
- Fruit
- Nectar
- Small snails and lizards occasionally
They use their specialized curved bill to probe crevices and dig in the soil for food. They also forage among leaf litter on the forest floor.
How do they reproduce and raise young?
Scimitar babblers have a unique communal breeding system. Key facts about their reproduction include:
- Social groups contain up to 10 birds
- Several females lay eggs in a shared nest
- Females share parenting duties
- Breeding season linked to monsoons
- Cup-shaped nests built in bushes or bamboo
- Typical clutch size is 2-4 eggs
- Incubation lasts 10-12 days
- Chicks fledge in 11-13 days
- Fledglings cared for by group for several weeks
This cooperative breeding behavior likely evolved to maximize resources and provide safety in numbers within their habitats.
How do they communicate?
Scimitar babblers have a wide range of vocalizations used to communicate within their social groups. These include:
- Loud, constant chattering
- Squeaking calls
- Whistling calls
- Melodious duetting between pairs
- Alarm calls to signal danger
- Contact calls to locate group members
Their loud, constant noise helps maintain group cohesion as they move through dense vegetation. Different calls likely convey information about food sources, predators, territorial disputes, etc.
What is their conservation status?
On the IUCN Red List, scimitar babblers are listed as Least Concern. However their population trends are decreasing due to the following threats:
- Habitat loss from deforestation
- Forest fragmentation
- Agricultural development
- Logging
- Urbanization
Accurate surveys of population numbers are lacking over most of their range. Conservation efforts focus on habitat protection, sustainable forestry practices, and reducing forest fragmentation in Southeast Asia.
What is their relationship to other babbler species?
Despite their common name, scimitar babblers are not closely related to true babblers in the family Leiothrichidae. Instead, they belong to the family Timaliidae, along with many other babbler-like species in Asia.
Some key differences between scimitar babblers and true babblers include:
| Scimitar Babblers | True Babblers |
|---|---|
| Family Timaliidae | Family Leiothrichidae |
| Long curved bill | Short pointed bill |
| Communal breeding | Pair breeding |
| Dull green plumage | Often bright yellow plumage |
Some examples of true babblers include the yellow-billed babbler and jungle babbler found in South Asia. Scimitar babblers are most closely related to other Timaliidae species like wren-babblers, scimitar babblers, and laughingthrushes.
Where did the name “scimitar babbler” come from?
The scimitar babbler gets its common name from two sources:
- Scimitar – Refers to their sharply downcurved bill resembling a Persian scimitar sword
- Babbler – A general name for chatty, social songbirds in the Old World tropics
Their scientific name Pomatorhinus hypoleucos means:
- Pomatorhinus – From Greek for “cover” and “nose”, referring to their nasal bristles
- hypoleucos – From Greek for “somewhat white”, referring to their pale underparts
Other common names include lesser scimitar-babbler and Indian scimitar-babbler.
How many species of scimitar babblers are there?
There are 12 recognized species of scimitar babblers in the genus Pomatorhinus. They include:

Fun Facts About Scimitar Babblers
- Scimitar babblers sunbathe by perching in a sunspot and ruffling up their feathers.
- Their downward curving bills help probe the ground and dig in leaf litter for food.
- Groups will mob potential predators like snakes and raptors by loudly calling and dive bombing.
- They roost together at night, with each bird finding its own perch on a bush or bamboo stem.
- Older siblings from previous broods often help care for new chicks at the nest.
- They take dust baths by wriggling in loose dirt to clean themselves and remove parasites.
- Like many bird species, scimitar babblers playfully chase each other and spar for no reason.
- Groups establish large communal territories up to 30 acres in size which they aggressively defend.
- Scimitar babblers have oddly shaped tongue tips that may help extract insects from crevices.
- Their Indonesian name “puyuh keris” means “dagger quail”, comparing them to a ground bird.
Conclusion
In summary, the scimitar babbler is a gregarious, noisy songbird endemic to tropical southern Asia. Despite their name, they belong to an old world babbler family separate from true babblers. They have a unique downcurved bill adapted for probing and digging, and exhibit a cooperative breeding system. Scimitar babblers prefer forest edges and scrublands, where their constant chatter provides contact between group members. Although still common in parts of their range, habitat loss threatens populations of this distinctive bird.
