As with all birds that are not eagles, a crow or raven is depicted by default as close, but they can uniquely be blazoned as speaking.
[1] The Cornish chough is also depicted in heraldry, which looks similar but has a red beak and feet.
[2][1] On the coat of arms of County Dublin and Fingal in Ireland, the crow was adapted from the raven banner of the Vikings, who had settled in the area.
[7] Matthias Corvinus of Hungary named his famous library (Bibliotheca Corviniana) after the bird.
[citation needed] The Corbet (Corbel, Corby, Corbe) family from the Channel Islands are also names having been corrupted over time from the Latin word corvus, for raven.
