Leviticus 11 adds the above. I really don't think that there are multiple genera of kites and ravens, at least. That suggests that kind = species.
There are multiple genera of kites, or what we call kites today anyway, around the world. There are two subfamilies of 'kites' within the very large raptor family Accipitridae, each containing several genera, and these two subfamilies have little more in common with each other than forked or square-tipped tails. Both kite groups are more closely related to various other lineages within the family than they are with each other. This illustrates one of the pitfalls of assuming same English name = same or very similar species. However, based on distribution the Leviticus verse would probably have meant Black Kite (Milvus migrans).
All ravens are in the genus Corvus, but I think there are two contender species for the bible passage - Common and Brown-necked. The bible passage could well have lumped both together.
