SYSTEMATICS & RANGE
Brown-backed Needletail occurs in the Oriental region. H. g. indicus, which is the taxon that has occurred in HK, is mainly resident in southwest India and Sri Lanka, the Andaman Islands, northeast India, Bangladesh and southeast Asia (Myanmar, Thailand, Cambodia and Vietnam); some individuals from the northern parts of the range move south in winter to the Thai-Malay Peninsula, probably to Borneo and possibly also Sumatra. H. g. giganteus is resident in the Malay Peninsula, the Greater Sundas and Palawan in the Philippines (Chantler and Boesman 2020).
CONSERVATION STATUS
