18That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great.

The term "fowls" and "unclean and hateful bird" are phrases that can indicate angelic or fallen angelic beings...

Revelation 18:2
And he cried mightily with a strong voice, saying, Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird.

It's not a hill I'll die on, but in my experience I've learned that most people know very little about angels. Angels are fearsome, bestial spiritual beings. Sometimes you don't know if an angel will reveal some vision, ancient wisdom, give a heavenly command, or roar and attack like a wild animal. Also consider that biblically speaking, angelic beings around throne of God are often called "creatures" or "beasts".

There are definitely classes of spirit beings that are no where near anthropomorphic. The cherubim are usually described as having the features of animals.

Whether this is intended to be taken literally or "just" as a characteristic feature of the beings described; both approaches would tend to indicate a nature as you are describing.
