Error identification is a type of competitive test where one needs to identify the grammatical errors in a sentence. Though termed as Sentence Correction, most often, problems in this topic need one to only classify sentence errors.
You could use the adjective, gaudy, to describe a noun. The noun, quail, could be used as the sentence subject (either direct or indirect). For example:
"The gaudy pheasant made the dull quail ashamed of its plain feathers."
