Avestruz literally translates to "ostrich". It's an unexpected and vivid animal metaphor in a song about relationship drama.
In the lyrics, the phrase "que es avestruz en mi vida" (that she is an ostrich in my life) is used to describe someone who is avoiding facing the truth or burying their head in the sand, much like the common misconception about ostriches. This unique and somewhat humorous comparison makes the word memorable and adds a layer of figurative language to the song's emotional conflict.
This song is a dramatic confrontation, a classic Pimpinela style! The singer is telling someone, presumably the ex-partner of their current love, not to blame them for the breakup. They insist, "que no me eche la culpa de su fracaso contigo" [don't blame me for your failure with him/her]. It's a pretty blunt message, telling this person to "sea valiente y busque en ella el motivo" [be brave and look for the reason within herself].
It gets even more intense! The singer claims that if there's any blame, it's shared between the two people who were in the relationship: "si aquí ha habido un culpable, sólo tú y yo lo hemos sido." [if there's been a culprit here, only you and I have been it]. They even say, "esto no hubiera pasado si ella no hubiera querido" [this wouldn't have happened if she hadn't wanted it]. The singer just wants to be left in peace, declaring, "esto ya está terminado" [this is already over]. It's a powerful and direct song about moving on and not accepting blame for someone else's past.
