Close kin of the Ents, Huorns were animated trees that possessed sentience. They were said to have voices but could only be understood by the Ents, not by the other peoples of Middle-earth. It is unclear if Huorns were simply trees that became aware or Ents that became more treeish over time (both varieties were thought to exist). Huorns were found in Fangorn Forest and possibly the Old Forest near Buckland. Legolas mentions that the Elves helped to wake up the trees. The Huorns decided the Battle of Helm's Deep, destroying Saruman's army of Orcs.
