Suppose we write:

pa', bIHtaH toQDuj'e'

there, are (the) birds of prey

If this is correct, then why would it be wrong to say {pa', chaHtaH chaH'e'} ? It's a simple substitution: "there, are they".

Because the correct way to link a pronoun with a noun is with the form noun pronoun, not noun pronoun noun'e'.
