I want to know the answer to the following question:
What allows for the identification of birds, particularly between species?
All the background I'm provided with is that "Birds sometimes use plumage to assess and assert social dominance, to display breeding condition in sexually selected species, or to make threatening displays, as in the sunbittern's mimicry of a large predator to ward off hawks and protect young chicks.". Is that enough to answer the question?
Answer: no
