The Indian robin (Copsychus fulicatus[note 1]) is a species of bird in the family Muscicapidae. It is widespread in the Indian subcontinent and ranges across Bangladesh, Bhutan, India, Nepal, Pakistan and Sri Lanka. The males of the northern subspecies have brown backs whose extent gradually reduces southwards, with the males of the southern subspecies having all-black backs. They are commonly found in open scrub areas and often seen running along the ground or perching on low thorny shrubs and rocks. The long tail is usually held up and the chestnut undertail coverts and dark body make them easily distinguishable from pied bushchats and Oriental magpie-robins.

Taxonomy
In 1760, the French zoologist Mathurin Jacques Brisson included a description of the Indian robin in his Ornithologie based on a specimen that he mistakenly believed had been collected in the Philippines. He used the French name Le grand traquet des Philippines and the Latin Rubetra Philippensis Major.[5] Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature.[6] When the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the 12th edition in 1766, he added 240 species that had been previously described by Brisson.[6] One of these was the Indian robin. Linnaeus included a brief description, coined the binomial name Motacilla fulicata and cited Brisson's work.[7] The type location was subsequently corrected to Puducherry in southern India.[8] The specific name is from the Latin fulicatus for "dusky" or "black".[9]

The Indian robin was formerly placed in the monotypic genus Saxicoloides. It was moved to Copsychus based on the results of molecular phylogenetic studies of birds in the family Muscicapidae
