<P> Pygostyle describes a skeletal condition in which the final few caudal vertebrae are fused into a single ossification , supporting the tail feathers and musculature . In modern birds , the rectrices attach to these . The pygostyle is the main component of the uropygium , a structure colloquially known as the parson 's nose , pope 's nose , or sultan 's nose . This is the fleshy protuberance visible at the posterior end of a bird ( most commonly a chicken or turkey ) that has been dressed for cooking . It has a swollen appearance because it also contains the uropygial gland that produces preen oil . </P>
