Create a new SVG or GIF parrot image with a riddler/joker theme. Check existing parrots in the repository for format (likely SVG or static images) and add the file to the appropriate directory (e.g., 'parrots' folder). Update any display logic if needed, such as adding the parrot to a list or array. Since the issue is from 2017 and has no activity, the task is straightforward and self contained.
