Hippogriff?

Whatever it is, it isn’t what I thought.
It has too many feathers, for one thing—
feathers, not scales, a bird and not a fish.
It might look like a lizard, but it’s not.
It doesn’t have feet, though clearly it can walk.
I think I saw it eat a little bit,
and then I watched it hunker down and sit
stock still for a minute, before it ambled off

and I lost sight of it completely. I can’t
say what it might be doing now. It’s some kind
of animal, of that I’m fairly sure,
smaller than an elephant, larger than an ant.
I don’t think its intentions are quite pure,
but what they are exactly, I can’t find.
