The Japanese white-eye, also known as mejiro, is a small songbird native to Japan and other parts of East Asia. It measures about 10 to 12 centimeters in length and is characterized by its olive-green plumage, white eye-ring, and yellow underparts. These birds are often found in gardens, forests, and parks, where they feed on nectar, fruits, and insects. Japanese white-eyes are social creatures, often seen in small flocks. They are known for their lively behavior and melodious songs. During the breeding season, they build cup-shaped nests in trees, where the female lays 3 to 5 eggs. Their adaptability to urban environments has contributed to their popularity among birdwatchers.
