Douglas Dewar, Birds of the Indian Hills
“ The Indian ring-dove (T. risorius) also occurs in the Western Himalayas. It is of a paler hue than the other doves and has no patch of black-and-white feathers on the sides of the neck, but has a black collar, with a narrow white border, round the back of the neck.One other dove should perhaps be mentioned among the common birds of the Himalayas, namely, the bar-tailed cuckoo-dove (Macropygia tusalia) . A dove with a long barred tail, of which the feathers are graduated, the median ones being the longest, may be set down as this species. ”
