Answer: Rich imagery that appeals to the readers' senses.
Explanation: Most of the excerpt consists of rich, mostly visual imagery: "Clear day," "pavement sparkling with sunlight," "pigeons fluttering," "nodding over a profusion of bread crumbs." There are no metaphors, definitions or humor, although the description of pigeons as "nodding" over bread crumbs (i.e., eating them) is somewhat amusing.
