The Red-flanked Bluetail, also known as the Orange-flanked Bush-robin, is a small, vividly colored passerine bird that belongs to the family Muscicapidae. This migratory bird is a true delight for birdwatchers and ornithologists, thanks to its striking plumage, elusive behavior, and wide-ranging habitat across Asia and parts of Europe.
Physical Description
The Red-flanked Bluetail is a medium-sized songbird, measuring approximately 13–14 cm in length and weighing around 10–18 grams. The species exhibits sexual dimorphism, with males being more vibrantly colored than females.
Male Plumage: Males boast a striking combination of cobalt blue on the upperparts and tail, with orange flanks and a white belly. Their throat and face often feature subtle streaking, and their overall appearance is elegant and eye-catching.
Female and Juvenile Plumage: Females are less conspicuous, with duller olive-brown upperparts, pale orange flanks, and a whitish belly. Juveniles resemble females but often have faint streaking on their head and breast.
Distribution and Habitat
The Red-flanked Bluetail is primarily found across the boreal forests of Eurasia. Its breeding range extends from Scandinavia and northern Europe across Siberia to Japan. During the winter months, it migrates southward to warmer regions in Southeast Asia, including northern India, southern China, and the Himalayan foothills.
This bird prefers cool, temperate forests with dense undergrowth, particularly coniferous and mixed woodlands. In winter, it can also be seen in scrublands, gardens, and wooded areas at lower altitudes.
Behavior and Diet
The Red-flanked Bluetail is a shy and solitary bird, often staying hidden in dense vegetation. However, its distinctive call—a high-pitched, melodic "tsee-tsee-tsee"—can give away its presence.
Diet: This insectivorous bird primarily feeds on small insects, spiders, and other invertebrates. During the non-breeding season, it supplements its diet with berries and fruits.
Foraging Behavior: It often hunts for prey by perching quietly and making sudden, darting movements to capture insects on the ground or in mid-air.
Breeding and Nesting
The breeding season of the Red-flanked Bluetail typically occurs from May to July. During this time, males establish territories and attract females through their vibrant plumage and melodious songs.
Nest: The female builds a cup-shaped nest on or near the ground, often concealed in a crevice, under a shrub, or in dense vegetation.
Eggs: She lays 4–7 pale blue eggs, which she incubates for about two weeks. Both parents are involved in feeding and raising the chicks, which fledge around two weeks after hatching.
