This passage certainly suggests that, at least by Moses's time, there were more than one Kind of hawk, of raven, of kite, and of heron. Also, Owl appears to be distinct from Little Owl or Great Owl, as are Eagle and Gier Eagle.
in
the last "kind" thread, i analyzed a few of the biblical kinds, and found it to be loosely and
colloquially equivalent to family. though looking at your reference, mine was hardly exhaustive in the bird area. perhaps i will co-op the bird part, and finish it here. but i doubt that's neccessary.
Penguins aren't mentioned, but is it possible that they are a Fowl That Creeps, Going Upon All Four? (sounds like reading Winnie the Pooh, doesn't it?) I sure can't think of any other birds that could even get nominated for that Kind/those Kinds - kiwis and ostriches go strictly on All Twos to the best of my knowledge. Auks and puffins, maybe....
i suspect that "going on all fours" is an idiom for being flightless. though it's really, really hard to tell -- locusts go on all fours, too.
