Heraldic

Deer of various types appear frequently in European heraldry. In the British armory, the term "stag" is typically used to refer to antlered male red deer, while "buck" indicates an antlered male fallow deer. Stags and bucks appear in a number of attitudes, referred to as "lodged" when the deer is lying down, "trippant" when it has one leg raised, "courant" when it is running, "springing" when in the act of leaping, "statant" when it is standing with all hooves on the ground and looking ahead, and "at gaze" when otherwise statant but looking at the viewer. Stags' heads are also frequently used; these are typically portrayed without an attached neck and as facing the viewer, in which case they are termed "caboshed".

Examples of deer in coats of arms can be found in the arms of Hertfordshire, England, and its county town of Hertford; both are examples of canting arms. A deer appears on the arms of the Israeli Postal Authority. Coats of arms featuring deer include those of Baden-Württemberg, Dotternhausen, Thierachern, Friolzheim, Bauen, Albstadt, and Dassel in Germany; of the Earls Bathurst in England; of Balakhna, Gusev, Nizhny Novgorod, Odintsovo, Slavsk and Yamalo-Nenets in Russia; of Åland, Finland; of Gjemnes, Hitra, Hjartdal and Rendalen in Norway; of Jelenia Góra, Poland; of Umeå, Sweden; of Queensland, Australia; of Cervera, Catalonia; of Selonia and Semigallia in Latvia; and of Chile.

Other types of deer used in heraldry include the hind, portrayed much like the stag or buck but without antlers, as well as the reindeer and winged stags. Winged stags are used as supporters in the arms of the de Carteret family. The sea-stag, having the antlers, head, forelegs and upper body of a stag and the tail of a mermaid, is often found in German heraldry.
