Why is the tail of a turkey called the popes nose?

Answer 1

The term "pope's nose" is a colloquial, informal term used to refer to the fleshy protuberance at the rear of a turkey, which is actually the uropygial gland. This gland secretes an oily substance that the turkey uses to preen its feathers. The origin of the term "pope's nose" is unclear, but it likely stems from the fact that the shape of this part of the turkey's anatomy vaguely resembles the shape of a bishop's or pope's hat.

Answer 2

Because it looks likes the Pope's nose

the Pope's nose is known as a pygostyle

"Pygostyle" is of Ancient Greek origin, literally meaning "rump pillar".

The phrase "parson's nose", from the notion that an English parson may 'have his nose up in the air', upturned like the chicken's rear end. The term must have been known as early as around 1400 AD, when a carpenter had been contracted to provide new choir stalls for St Mary's Church, Nantwich.[verification needed] The vicar was either slow to pay the artisan, or did not pay at all. In retaliation, on the last misericord in the stalls, the carpenter carved a bird with an image of that Vicar's face with protuberant nose as rump. The carving is still visible today.[5]

A similar derivation applies to the phrase "Pope's nose", which may have originated as a derogatory term meant to demean Catholics in England during the late 17th century.[citation needed]

"Sultan's nose" probably was coined some time during the Early Modern era wars against the Ottoman Empire.[citation needed]
