I think we had apple pie, but it was crumb topped. The origin of the pea name is obvious. Ears too have inspired some food names. The twisted pretzel was originally made as a religious symbol to resemble the crossed arms folded in prayer. The name comes from Old High German, brezitella, meaning little branch or little arm.
Birds are present in several food names.
In fact, pie probably derived from Magpie. Mag, a nickname for Margaret, often applied to a chatterbox, the pie part is said to refer to the bird's collecting a variety of things in its nest, since pies may contin a variety of ingredients. From penna also comes panache via French as a plume of feathers atop a helmet. The word developed to mean a swaggering display. Later, the English used panached for things striped like a feather.
