Baby Eagles

The Austrian Empire had a two-headed eagle as its symbol. After the abolition of Austria-Hungary, Austria took as its symbol a one-headed eagle in the modern coat of arms of Austria.
Prussia, and later Germany have used a black eagle as their national symbol.
The Spanish Catholic monarchs, Isabella and Ferdinand, used the eagle as a part of the royal shield representing Saint John the Evangelist. The eagle was again on the Spanish shield under the Francoist regime and the transition to Democracy (1939–1981).
