Douglas Dewar, Birds of the Indian Hills
“ As we have seen, most bulbuls are inoffensive, respectable birds, that lead a quiet, domesticated life. The cock and hen are so wrapped up in one another as to pay little heed to the outer world. Not so the black bulbuls. These are the antithesis of everything bulbuline. They are aggressive, disreputable-looking creatures, who go about in disorderly, rowdy gangs. The song of most bulbuls consists of many pleasant, blithe tinkling notes; that of the black bulbul, or at any rate of the Himalayan black bulbul, is scarcely as musical as the bray of the ass. ”
