Oriental Greenfinch (Chloris sinica) – Wildlife of Japan
Introduction
The Oriental Greenfinch is a small finch that can be seen in many parts of Japan. It often appears in parks, farmland, riverbanks, and other open areas.
One of its most noticeable features is the bright yellow flash on its wings when it flies. In Japan, this bird is known as Kawarahiwa.
Appearance
The Oriental Greenfinch is a small finch about 14 cm in length. Its body is olive-brown to grayish green, and it has a thick conical bill suited for cracking seeds.
The most distinctive feature is the bright yellow band on the wings, which becomes very visible in flight. The tail also shows yellow along the edges.
Habitat & Distribution
In Japan, the Oriental Greenfinch breeds mainly from Kyushu northward through Honshu and Hokkaido.
It prefers open habitats rather than dense forests. Typical environments include farmland, riverbanks, grasslands, woodland edges, and city parks.
Because it adapts well to human environments, it can also be seen around towns and suburban areas.
Behavior
Oriental Greenfinches are often seen perching on tree branches or power lines. Outside the breeding season they may gather in small flocks.
Their flight is fairly direct, and the yellow wing markings stand out clearly when they take off.
Diet
The Oriental Greenfinch mainly feeds on seeds from grasses and plants. It often searches for food on the ground in open areas.
Its strong bill allows it to crack hard seeds efficiently.
Reproduction
During the breeding season in spring and early summer, the Oriental Greenfinch builds a small cup-shaped nest in trees or shrubs.
The female typically lays 3 to 5 eggs. After hatching, the parents feed the chicks until they are ready to leave the nest.
Where to See in Japan
This species can be found in many everyday landscapes across Japan.
Typical places to look include:
• urban parks
• farmland
• riverbanks
• grasslands
• suburban green spaces
In autumn and winter, they may gather in small flocks, which can make them easier to notice.
Similar Birds
A bird that may sometimes be confused with the Oriental Greenfinch is the Eurasian Siskin (Spinus spinus).
The Eurasian Siskin is smaller and usually shows darker markings, while the Oriental Greenfinch has a thicker bill and a broader yellow wing band.
Author’s Impression
While observing wildlife in Japan, I often encounter Oriental Greenfinches in open areas such as fields or riverbanks.
At first they may appear rather plain, but when they fly, the bright yellow on the wings suddenly becomes visible and makes the bird surprisingly striking.
