In heraldry, an attitude is the position in which an animal, fictional beast, mythical creature, human or human-like being is emblazoned as a charge, supporter or crest. Many attitudes apply only to predatory beasts and are exemplified by the beast most frequently found in heraldry—the lion. Some other terms apply only to docile animals, such as the doe. Other attitudes describe the positions of birds, mostly exemplified by the bird most frequently found in heraldry—the eagle. The term naiant (swimming), however, is usually reserved for fish but may also apply to swans, ducks or geese. Birds are often further described by the exact position of their wings. The term segreant is apparently reserved for mythical creatures, as this term is the approximation of rampant as it applies to winged quadrupeds such as griffins and dragons.
