Tickell's Blue Flycatcher

Cyornis tickelliae

梯氏仙鹟

IUCN: Least Concern Found in China

Introduction

Small flycatcher (family Muscicapidae) of Asia. Males have bright blue upperparts with rufous throat and breast. Inhabits wooded habitats including forest edge, shaded gardens, and streamside thickets. Perches upright on low branches and catches flying insects via aerial sallies. Song consists of a series of clicks followed by an abrupt whistle. Occurs in human-modified landscapes where insects congregate. Not considered threatened, but dependent on forest understory cover.

Description

A compact, upright-perching flycatcher measuring 11-12 centimeters in length. The adult male displays vibrant cobalt-blue upperparts and face, contrasting with rich rufous-orange on the throat and upper breast, while the remaining underparts are pure white. Females are notably duller overall, with subdued blue-gray upperparts but retain bright blue highlights on the brow, shoulder, rump, and tail. Juveniles are heavily streaked and spotted, appearing predominantly scaly brown on the head, mantle, and breast, with only the wings and tail showing blue coloration. Regional populations exhibit considerable variation in plumage tones and bill length, with Sri Lankan birds (C. t. jerdoni) being particularly dark and long-billed.

Identification

The bright blue upperparts combined with rufous throat and breast distinguish this species from the similar blue-throated blue flycatcher, which has a blue rather than rufous throat. The Indian blue flycatcher lacks the bright blue rump and shows more extensive rufous on the underparts. In the Eastern Ghats, careful identification is required as this species hybridizes with the pale-chinned blue flycatcher, producing intermediate forms sometimes classified as subspecies vernayi. The species often sits upright on exposed perches within low cover, allowing observation of the diagnostic underpart coloration. Note the female's subtle blue shoulder and rump patches against the otherwise dull plumage.

Distribution & Habitat

This species breeds across tropical Asia from the Indian subcontinent east through Bangladesh to western Myanmar. Several subspecies reflect regional population differences: the nominate form occupies India, Nepal, and Myanmar; C. t. jerdoni is endemic to Sri Lanka; C. t. indochina occurs from Myanmar through Thailand into Cambodia and Vietnam; C. t. sumatrensis is found in southern Thailand, peninsular Malaysia, and northeast Sumatra; and C. t. lamprus is restricted to Anamba Island. The species inhabits dry forest, scrub, bamboo thickets, and well-vegetated gardens, with a particular affinity for shaded areas with thick understory and wooded streams.

Behavior & Ecology

Primarily an aerial hawker, this bird sallies from perches to catch flying insects in flight but also gleans crawling insects from vegetation and the ground. Its diet includes termites, earwigs, and other insects, with larger prey such as bush frogs occasionally taken during breeding season. Unusually for a flycatcher, it sometimes continues feeding after dusk. The metallic song consists of short clicks followed by five or six descending notes that end abruptly, resembling the call of the spot-breasted fantail. Alarm calls include churrs and clicking notes. The breeding season spans April to August (March to June in Sri Lanka), with nests constructed in tree holes or rock crevices lined with fine grass and fibers, containing 3-5 eggs.

Conservation

The conservation status of this species has not been formally assessed by the IUCN Red List. While no specific population trends are documented, the species' adaptability to modified habitats including gardens suggests it maintains healthy numbers across much of its range. However, ongoing forest loss in parts of its distribution may affect local populations dependent on intact forest understory.
