Answer:
Metaphor.
Step-by-step explanation:
Lines 11 and 12 have a strong metaphor, which is the term that can describe these lines.
Metaphor is the subjunctive comparison between two elements that have a certain similarity. In these lines the author compares the bird in the poem, with the other birds, he shows that this bird is different from the others, but one day the dust will cover everything (referring to a burial), that is, on the day the bird dies, it will be like any other bird.
