Subspecies
Sometimes thought to form a superspecies with Burmese Shrike (Lanius collurioides), the two being separated geographically by R Brahmaputra. Other studies suggest close relationship either with Red-backed Shrike (Lanius collurio) on basis of coloration or with Brown Shrike (Lanius cristatus). Also resembles Lesser Grey Shrike (Lanius minor) in territorial flight display and Long-tailed Shrike (Lanius schach) in vocalizations. Subspecies intergrade in eastern Pakistan (north-western Punjab and Sind).
The following 2 subspecies are recognised:
nargianus Vaurie, 1955 - Breeds south-eastern Turkmenistan, south-eastern Iran
(Hormuzgan, Sistan and Baluchistan, probably also Khorasan),
Afghanistan and Pakistan (Baluchistan east to Sind and Punjab).
vittatus Valenciennes, 1826 - Southern and eastern Pakistan,
Kashmir, India (except northern and north-east) and southern Nepal.
