Northern Cardinal 北美紅雀 or Redbird or Common Cardinal (Cardinalis cardinalis)
最近有個用 Angry bird 開玩笑的 NG 封面，其實 Angry bird 應該是根據 Cardinal 的形象改的，它在美州比較常見，是 Kentucky 州的州鳥。
最接近 Angry bird 形相的是 University of Louisville's 體育吉祥物

Cardinal Bird
The University of Louisville's athletic symbol, chosen sometime after 1913, is a Cardinal. The Cardinal bird was chosen to give U of L statewide identification, since the Cardinal is the state bird of Kentucky.
The school colors - cardinal red, black and white - were adopted at the suggestion of Mrs. John L. Patterson. In printing terms, the U of L color for red is PMS 485. All of the University of Louisville's present logos are trade marked.
