The Golden Eagle is the official bird and symbol of Mexico, and its imagery dates back to pre-Colombian codices of the Aztecs. However, it is very likely that the actual bird is the Northern Caracara, a falcon.
This bronze centavo was issued from 1905 through 1949. There was also a slightly smaller version issued in 1915 (along with the 1915 issue of the coin shown here). Not sure why they would do that.
