It's right there in scripture if one just reads a couple more verses.
Genesis 1:24 KJV
(24) And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.
Things reproduce with their kind. If you read even further to Leviticus, it gets as specific as vulture, kite, owl, raven, and hawk.
Leviticus 11:13-16 KJV
(13) And these are they which ye shall have in abomination among the fowls; they shall not be eaten, they are an abomination: the eagle, and the ossifrage, and the ospray,
(14) And the vulture, and the kite after his kind;
(15) Every raven after his kind;
(16) And the owl, and the night hawk, and the cuckow, and the hawk after his kind,
You are expected to be able to deduce "kind" from usage. A hawk is not the same kind as a raven, nor the owl as the kite. But kites mate with kites and they have baby chick kites. Owls nest with owls and they have baby owls, not dragons or cattle or whales. You may have a big owl or a small owl or maybe an owl with different coloration or a slightly hooked beak, but it will still be an owl.
