The Hebrew word owph, that we normally translate as “bird” in Genesis 1 and Genesis 7, means creatures with wings. This obviously includes birds (the predominant type here) but also other winged creatures — such as bats, flightless birds, flying reptiles, etc. For example, ostriches and bats are included under this word owph in Leviticus 11. Most commentators recognize that Genesis 7:3 (see above), “seven each of the birds of the air,” is tied to the backdrop of clean creatures in Genesis 7:2 (see above). Verse 2 lists all animals coming onboard the ark in two categories — clean and unclean — and how many of each. When verse 3 immediately after that lists 7, it is discussing a subgroup of the clean animals, otherwise, verse 2 is in error. However, contextually, this doesn’t mean all winged/flying creatures came by 7 but instead limited to 7 of the clean ones. Pteranodons and pterodactyls are not among the clean creatures defined per the Bible (Leviticus 11 and Deuteronomy 14). For instance, Leupold writes: In v. 3 the idea of “the birds of the heavens” must, of course, be supplemented by the adjective “clean,” according to the principle laid down in v. 2.24 Likewise, Dr. John Gill, who agrees when discussing the birds, writes: That is, of such as were clean; seven couple of these were to be brought into the ark, for the like use as of the clean beasts, and those under the law.
