Bede, on Gen 1:22

“And he blessed them, saying: Increase and multiply, and fill the waters of the sea: and let the birds be multiplied upon the earth.”

“And God saw that it was good, and He blessed them, saying: Be fruitful and multiply, and fill the waters of the seas, and let birds multiply on the earth. And there was evening and there was morning, a fifth day. When He said, be fruitful and multiply, and fill the waters of the seas, it pertains to both kinds of creatures made from the waters, that is, both to fish and to birds, because just as all fish can live only in the waters, so too there are many birds which, although they sometimes rest on the lands and propagate their offspring, not only feed from the land but also from the sea, and prefer to inhabit marine dwellings rather than terrestrial ones. But when He adds, and let birds multiply on the earth, it pertains to both kinds of birds, that is, both those that come from the waters and those that feed from the earth, because indeed even those birds which do not know how to live without waters often hide much of the time under the depths of the waters like fish, occasionally tend to come out onto the lands, especially when they are breeding and nurturing their young.”
