Rashi
כל צפור טהרה תאכלו ALL CLEAN BIRDS YOU MAY EAT — 'All' — this is intended to permit as food also the bird that is set free in the case of a leper (i.e. at his purification rite; Leviticus 14:7) (Sifrei Devarim 103:1; Kiddushin 57a).
Chizkuni
כל צפור טהורה, “any ritually pure bird;” whenever the Torah uses the term צפור instead of עוף for “bird,” it is automatically referring to a ritually pure species of birds. The latter term, however, is used on different occasions for either category of birds. Ritually impure birds are always described as עוף. (Sifri)
Ibn Ezra
bird is a generic term, as I explained earlier [comment on Genesis 15: 10], when I pointed out that “turtle-dove” [Genesis 15: 9] and “pigeon” [Genesis 15: 9] were two individual species within the same generic term. Similarly, dayyah and raכah are specific terms classified under the more general term “ da כ ah ” [Leviticus 11: 14]; here Scripture gives additional detail.
