In the text by Chimalpahin Cuauhtlehuanitzin, the eagle is devouring something, but it is not mentioned what it is. Still other versions show the eagle clutching the Aztec symbol of war, the Atl-Tlachinolli glyph, or "burning water". The bird featured on the Mexican coat of arms is the golden eagle. This bird is known in Spanish as "águila real" (literally, "royal eagle"). In 1960, the Mexican ornithologist Martín del Campo identified the eagle in the pre-Hispanic codex as a northern caracara or "quebrantahuesos", a species common in Mexico (although the name "eagle" is taxonomically incorrect, as the caracara is a type of falcon). Even so, the prickly pear cactus is considered the Mexican plant for official purposes, and for the same reason is considered the official cactus of Mexico. The National Anthem of Mexico () was officially adopted in 1943. The lyrics of the national anthem, which allude to Mexican victories in the heat of battle and cries of defending the homeland, were composed by poet Francisco González Bocanegra in 1853, after his fiancée locked him in a room. From 1854 until its official adoption, the lyrics underwent several modifications due to political changes in the country. Currently the full national anthem consists of the chorus, 1st stanza, 5th stanza, 6th stanza and 10th stanza. At the same time the lyrics were composed, a set of music was chosen, the winner was Juan Bottesini, but his entry was disliked due to aesthetics. This rejection caused a second national contest to find music for the lyrics. At the end of the second contest, Jaime Nunó, a Spanish-born band leader, arranged the music which now accompanies González's poem. The anthem, consisting of ten stanzas and a chorus, entered into use on September 16, 1854. During the second anthem competition, Nunó was the leader of several Mexican military bands. He had been invited to direct these bands by President Santa Anna, whom he had met in Cuba. The modification of the lyrics was ordered by President Manuel Ávila Camacho in a decree printed in the Diario Oficial de la Federación. The de jure or official language of Mexico is Spanish. Nevertheless, there are still people who only speak indigenous languages. On December 8, 2005, Article 39 of the national symbols law was adopted to allow for the translation of the lyrics into the native languages.
