[Arabian Nights] ...words characterize animal sounds

another excerpt from Burton's Arabian Nights:
Presently, O my lady, I espied a noble steed, black as the murks of night when murkiest, standing ready saddled and bridled (and his saddle was of red gold) before two mangers, one of clear crystal wherein was husked sesame, and the other also of crystal containing water of the rose scented with musk. When I saw this I marveled and said to myself, "Doubtless in this animal must be some wondrous mystery." And Satan cozened me so I led him without the palace and mounted him, but he would not stir from his place.

So I hammered his sides with my heels, but he moved not, and then I took the rein whip and struck him withal. When he felt the blow, he neighed a neigh with a sound like deafening thunder and, opening a pair of wings, flew up with me in the firmament of heaven far beyond the eyesight of man. After a full hour of flight he descended and alighted on a terrace roof and shaking me off his back, lashed me on the face with his tad and gouged out my left eye, causing it roll along my cheek.Then he flew away. I went down from the terrace and found myself again amongst the ten one-eyed youths sitting upon their ten couches with blue covers, and they cried out when they saw me: "No welcome to thee, nor aught of good cheer! We all lived of lives the happiest and we ate and drank of the best. Upon brocades and cloths of gold we took our rest, and we slept with our heads on beauty's breast, but we could not await one day to gain the delights of a year!" Quoth I, "Behold, I have become one like unto you and now I would have you bring me a tray full of blackness, wherewith to blacken my face, and receive me into your society." "No, by Allah," quoth they, "thou shalt not sojourn with us, and now get thee hence!" So they drove me away.

what does "tad" mean in the above?
while reading about the horse that neighed, i thought of words that characterize animal's cries. Here's a list:
hourses neigh, donkeys bray, doves coo, cats meow and purr, dogs growl and bark, puppies yelp, ducks quack, rattle snakes rattle, hogs grunt, snakes hiss, wolves howl, owls hoot, flies buzz, goats bleat, lions roar, hens cackle and cluck, crows caw, birds chirp, frogs croak, bees drone.
And
whales sing?,
hyenas laugh?,
dolphins beat?
What about the following animals?
bull,
monkey,
rooster,
elephant.
I'm certain there's a word for the rooster's morning cry?

also, the following words must have a animal that befit each?: wail, cry, sob, shriek? tweet?
This reminds me of H G Well's War of the Worlds, where Martians ululate!
PS does anyone know what's misc.writing for? i wonder if i should keep posting there.
