Rashi
צפור כל כנף [EVERY] BIRD OF EVERY KIND — The word צפור is in the construct state, viz.. birds of every kind of wing, thus including locusts (Chullin 139b). The word כנף means “wingfeather”, as (Leviticus 1:17) “He shall rend it by the wings thereof”, for even its feathers were offered as a sacrifice. Also here, the meaning is, birds with any kind of semblance of wing.
Chizkuni
כל צפור כל כנף, “every bird, every wing.” According to Bereshit Rabbah 32,8, these apparently superfluous words are to tell us that every one of these birds some of which Noach would use as sacrifices later on, were complete, whole, i.e. did not have a single feather missing, as this would have disqualified them as potential sacrifices. None had damaged reproductive organs.
Radak
המה..כל צפור, כל כנף, when the Torah used the word עוף it referred to any creature that could fly, יעוף. Now the Torah became even more explicit, writing כל צפור, a generic term for all the larger birds. The expression צפור includes both the ritually pure birds as well as the ritually impure ones. כל כנף, the Torah adds more detail, writing that every creature that has wings was included in those entering the ark; alternatively, the word could be understood as an adjective, i.e. “every feathered creature.”
