I do not recognize this motif. Is it a new, modern fable, created by the new collective mind in new, urban – global surroundings of our world (blablabla, etc)?
Is this gang of three a simple predator – prey chain?
Or, they are a group of individuals formed by the same interests?
Maybe author’s intention was to confuse us, or better yet, to get us thinking about what is really important in life? If so, what is that really important thing? Why did he choose to portray a parrot (is it a parrot?? – discuss), not a somewhat more expected symbol, like an eagle or something? But, in the city, have you seen an eagle recently (apart from the zoo or TV)? Maybe that was the point, there are more parrots than eagles in the city?
Or author did not have such intention; rather, he wanted to show something that looks cool? Does it diminish its value then?
