behor

'behor' means “young” and by extension “in his prime”.
'behor' might be cognate with Old English. Up to the 15th century, 'brid' or 'bird' meant “young” was used in English not only to describe a young animal in its prime - whether a fish, a mammal, or a child or a bird. Old English speakers used 'fugel' as the standard term for bird. This eventually evolved into “fowl” (and in Dutch 'vogel').
Eventually, the usage evolved to indicate only young birds, and eventually lost the implication of “young” to become a reference to a feathered animal regardless of age.
This might seem a bit of a stretch - after all 'behor' and 'bird' don't really sound all that similar. The weird thing is though, “Bird” doesn’t have cognates in any other Germanic language. Linguists have no explanation for where the English word “bird” came from. Granted this is not conclusive evidence, but it is an interesting possibility.
