Red-flanked Bluetail ルリビタキ Scientific name: Tarsiger cyanurus

The Red-flanked Bluetail is one of Japan’s most beautiful small mountain birds. In Japanese it is called ルリビタキ / Ruribitaki. The adult male is especially striking, with vivid blue upperparts, a bright blue head and back, orange-red flanks, and a white eyebrow. The female and immature birds are mainly olive-brown, with a warm orange tail and flanks.

In Japan, the Red-flanked Bluetail is closely associated with mountain forests, subalpine woodland, dwarf pine, bamboo grass, and forest edges. During the breeding season it prefers cooler, higher elevations. In winter, many birds move down to lower mountains, woodland edges, parks, and gardens, making them easier to encounter.

The brilliant blue male, marked with vivid orange-red flanks and a white eyebrow, is one of the most beautiful sights in Japan’s highland woodland. Females and young birds are more subtly colored, with warm orange tails and flanks. The ルリビタキ breeds mainly in cool mountain habitats and often descends to lower elevations in winter, bringing a flash of blue to forests, parks, and gardens.

The Red-flanked Bluetail is a small and striking songbird of mountain forests, woodland edges, and shrubby habitats in Japan. The male is especially beautiful, with deep blue plumage, a bright white eyebrow, and vivid orange flanks and tail sides. Females and immature birds are mainly brownish with a warm orange wash on the flanks and tail.

It is often found quietly moving through dense undergrowth, searching for insects and other small invertebrates on or near the ground. In winter, it can also appear in parks, gardens, and wooded areas at lower elevations. Its gentle movements and vivid blue-and-orange plumage make it one of Japan's most attractive small forest birds.
