Introduction
The Ashy-crowned sparrow-lark (Eremopterix griseus) is a small, sparrow-sized member of the lark family. Primarily found across the plains of South Asia, this bird is well-known for its ground-dwelling habits and the dramatic aerial displays performed by males during the breeding season.
Physical Appearance
This species measures approximately 12 cm in length and features a thick, finch-like bill and very short legs. There is significant sexual dimorphism: males exhibit a contrasting black-and-white face pattern, an ashy crown, and a black underbelly. Females are sandy brown and look remarkably similar to female house sparrows, though they appear stockier with shorter necks.
Habitat
The Ashy-crowned sparrow-lark thrives in open, flat landscapes. Its preferred habitats include:
- Open scrublands and grasslands.
- Semi-cultivated fields and fallow lands.
- Dry river basins.
- Tidal mudflats and areas with bare ground.
Diet
These birds are primarily foragers that find food on the ground. Their diet consists of:
- Grass seeds and grains.
- Tiny insects.
- Small beetles.
Breeding and Nesting
During the breeding season, males are easily identified by their undulating and dive-bombing flight displays, which are accompanied by a long, descending whistle. They typically nest on the ground, utilizing small depressions protected by grass or stones to camouflage their eggs.
Behavior
Unlike many other birds, the Ashy-crowned sparrow-lark does not perch in trees or bushes. They are almost exclusively ground-dwelling, though they may occasionally be seen perching on low wires. They are often found in pairs or small flocks foraging on bare patches of earth.
Conservation Status
The Ashy-crowned sparrow-lark is currently listed as Least Concern on the IUCN Red List. It remains common and widespread across its native range in India, Pakistan, and Sri Lanka.
Interesting Facts
- The male's ashy crown distinguishes it from the closely related Black-crowned sparrow-lark.
- Their flight display involves a steep climb followed by a series of nose-dives.
- Despite their resemblance to sparrows, they belong to the Alaudidae (lark) family.
- Their sandy coloration provides excellent camouflage against sun-baked earth.
Tips for Birdwatchers
To spot an Ashy-crowned sparrow-lark, scan bare ground or dry fallow fields rather than looking in the foliage. During the breeding season, listen for a sharp, whistling call and look up to see the male's acrobatic "dive-bombing" maneuvers in the sky.
Conclusion
The Ashy-crowned sparrow-lark is a resilient and charming inhabitant of South Asia's open plains. Whether identified by the male's bold markings or their unique ground-based lifestyle, these birds are a highlight for any birdwatcher exploring the region's scrub and grasslands.
