[1] In the Polish heraldry, the Silesian eagle is usually not crowned (with the exception of Cieszyn Silesia), in the Czech and German it is usually the opposite.

For example, in the Duchy of Świdnica, the coat of arms depicted a half red–black eagle with a crescent on a silver and golden background.

Also in 1993, in the coat of arms of the Czech Republic, a black eagle with crescent and a crown on its head, symbolizing Silesia, was placed in one field.

[2] In 1957, the coat of arms of Liechtenstein was adopted, on which a black eagle with crescent and a crown on its head, symbolizing Silesia, was placed.

[3] The Constitution of Saxony from 1992 allows the use of the coat of arms of Lower Silesia in the Silesian part of the state on an equal footing with Saxon symbols.

[1] On the basis of the seal on documents from the years 1257 and 1260, it is stated that the golden eagle was inherited by representatives of all Piast lines in Upper Silesia from Duke Władysław of Opole–Racibórz.
