Hmmm. A baby ostrich is apparently just a chick.
Strider's name explains what he mostly seems to do, but I guess it's stretching it too far to call it an occupation ....
[Checks clue again]
Ah, it says job description, not occupation.
I guess STRIDER could describe the job of a Ranger?
But where would he (or the clue) almost keep a juvenile ostrich, I wonder?
My hunch is nowhere, and that I'm wrong.
