How to recognise it
The Yellow-browed Sparrow is a short-tailed, long-legged sparrow with a relatively stout bill. Its most distinctive feature is a bright yellow eyebrow (supercilium) set against a grey head with fine dark streaking.
The upperparts are grey with darker streaking, while the underparts are primarily grey on the breast and flanks, becoming off-white on the belly. The wing shows yellow patches at the bend, visible when perched.
Both sexes look identical. Juveniles are similar but duller overall, with less yellow on the face and subtle streaking across the breast.

Its song and calls
The Yellow-browed Sparrow's song is a series of high-pitched, buzzy notes, often described as 'tsee-tsee-tsee-tseee'. Their call is a short, sharp 'chip'.
During the breeding season, males sing from exposed perches to defend territory and attract mates.

Tips for seeing it
- Look for them in grassy areas near forest edges or in open woodlands
- Listen for their distinctive high-pitched, buzzy song
- Observe early morning or late afternoon when they are most active
- Use binoculars to spot their characteristic yellow eyebrows
What it eats
The Yellow-browed Sparrow primarily feeds on seeds from grasses and other plants. They supplement their diet with insects, especially during the breeding season.
These birds often forage in small flocks, pecking at the ground or low vegetation.
Nesting and breeding
Breeding typically occurs during the rainy season, which varies across their range. Yellow-browed Sparrows form monogamous pairs during this time.
The female constructs a cup-shaped nest using grasses and plant fibres, usually placed low in dense vegetation or on the ground. The clutch typically consists of 2-3 pale blue or greenish eggs with brown speckles.
Incubation lasts about 12-14 days, primarily carried out by the female. Both parents feed the nestlings, which fledge after approximately 10-12 days.
Behaviour
Yellow-browed Sparrows are typically seen foraging on the ground or in low vegetation, hopping and scratching for food.
They are often found in small groups or pairs and can be quite secretive, quickly retreating to cover when disturbed.
Conservation
While the Yellow-browed Sparrow is currently listed as Least Concern, habitat loss due to deforestation and agricultural expansion poses a potential threat.
Conservation efforts focus on protecting their woodland and grassland habitats across their range.
