Reflex

The grey squirrel and blackbird continued their month-long debate over which critter excelled.

"Your last point was weak, squirrel, about your master tree-climbing? Didn't you notice we just fly to any spot? Done. Don't do much climbing!"

The grey squirrel snorted back in reply, "And, a fine target you are in the air, while we've actually learned to hide! Doesn't make much evolutionary sense, but we you've come a long way since your dominant, prehistoric day."

That last part stung the blackbird, but his peak-smile was frozen with pride. He hated any reference to his size or history. "True, our flight has soared thru strange atmosphere, but we've survived, we're still here! Have you ever been huge, squirrel, in any way?"

Just then, human sounds were heard in the park, very near them, voices and steps. As if reacting thru precisely the same reflex, grey squirrel and blackbird instantly scurried and flew to the exact same perch, higher up in the big tree. Where they- momentarily- shared a rare chuckle, before resuming their quarrel.
