Common Reed Bunting or House Sparrow?
Here's how to tell the difference
Common Reed Bunting
House Sparrow
Common Reed Bunting
Emberiza schoeniclus
General appearance
The Common Reed Bunting is a small bird species. It has a relatively hefty body, compared to a sparrow, with a sturdy beak. The bird is typically around 13.5-15.5 cm long, sporting a wingspan around 21-26 cm. Key colours are black, white, and a variety of browns. The plumage can be somewhat variable.
Male vs female
Male Reed Buntings tend to be more striking in appearance than their female counterparts. They possess a black head with white collar contrasted against a brown back, while females exhibit a more muted, uniform brown colour all over. The males lose their black colouring after the breeding season and resemble the females until the following spring.
Juvenile
Juvenile Reed Buntings look very similar to adult females. They have a mottled brown and cream appearance overall. Over time, they gradually develop into the more distinctive adult colourations as they mature.

Passer domesticus
General appearance
House sparrows are small, stocky birds measuring about 16 cm in length. They have a short tail and a stout bill. Their plumage is predominantly brown, with black streaks on their back and wings. This common bird has a distinctive, somewhat rounded head and a smooth body shape that helps in identifying it in urban and rural areas alike.
Male vs female
Male house sparrows are more vibrant with a gray crown, a chestnut-brown nape, and white cheeks. They have a distinctive black bib on their throat, which can vary in size seasonally. In contrast, females are duller with a more uniform brown coloration, lacking the bold markings of males. Their underparts are a plain grayish-brown, and they have a more pronounced eye stripe behind the eye.
Juvenile
Juvenile house sparrows resemble females but are even paler, with grayish-brown plumage and softer streaks. They lack the developed throat patch and bright head pattern found in adults. Juveniles gradually acquire adult coloration through moulting, becoming distinguishable by their more uniform brown appearance and subtler facial markings.

Visual differences
The Common Reed Bunting and House Sparrow exhibit distinct visual differences. The Reed Bunting (5.3-6.1 inches) is slightly smaller than the House Sparrow (5.9-6.7 inches) and features a more variable black, white, and brown plumage. Males have a striking black head and white collar. House Sparrows have a consistent brown plumage with black streaks; males show a gray crown and black bib. The Reed Bunting's beak is sturdier, while both species have short, stout bills. Females of both species are brown but differ in patterning and subtle color tones.
Key differences and behavior
The Common Reed Bunting (Emberiza schoeniclus) and House Sparrow (Passer domesticus) display distinct behavioral traits. Reed Buntings favor wetlands and adapt to reed beds for nesting, employing "injury feigning" to distract predators. In contrast, House Sparrows thrive in urban settings, using man-made structures for nesting and are social, often seen in choruses. Both species feed on seeds and insects, but Reed Buntings shift to a more insect-focused diet in breeding seasons, while Sparrows opportunistically consume urban food scraps. Reed Buntings engage in song-based courtship from perches, whereas Sparrows display with body movements and vocalizations. Reed Buntings are semi-migratory, moving to warmer regions in winter, unlike the often sedentary Sparrows.
