The ostrich is a gawky, flightless bird, famed for its ability to digest the non-digestible. For that reason, it’s frequently depicted with a bit of iron in its mouth (usually a horseshoe, sometimes a key), even when not so blazoned. The ostrich is a period charge, found in the arms of Robard of Kyrton, c.1460 [RH]. The ostrich is statant and close by default.
