Hawks

Hawks were swift birds of prey, smaller than Eagles, but just as sharp-eyed. Though the Eagles were the best known of Manwë's messengers, we're also told that there were hawks among the ranks of his servants, watching Middle-earth and bringing back news to their noble master on Taniquetil. Other forces also used them as servants, and far above the crebain that spied for Saruman in the War of the Ring, Aragorn reported that he had seen hawks hovering, watching the lands far below.
