Thrushes

Thrushes are large songbirds. Nearly as intelligent and gifted as ravens, they are among Radagast the Brown's principal messengers and scouts. They are also long-time friends of wise Men in many regions, but especially in Erebor and the Dale. Dwarves admire them, but cannot communicate with them because the Thrushes speak too quickly and in too high pitched voices (one would imagine that Ents would have similar problems). The thrush language (Throsel-tunge) can, however, be learned by Men and Elves who care enough to make a study of such things. Thrushes are very keen eyed and have a strong streak of curiosity in them, so they make excellent scouts.
