Problem:

Some time ago I tasted ostrich meat, and what was amazing to me was that the meat very much resembled beef, much more than it resembled chicken, turkey or duck meat. And even more than lamb and pork resemble beef.

The resemblance is both in look, both raw and grilled, and in taste (only tried grilled). I would have thought that the meat of related animals would have similar taste.

Required:

Question: Why is it that the meat of an ostrich, which is a bird, doesn't taste like that of other birds? Please describe it.
