Wildlife Through The Window

I was sitting at my desk, uploading bird pics, when something outside caught my eye.  This little sweety was watching my every move. Until I turned the camera on him.
Here's an old rhyme I dug up – seems apt!
Once I saw a little bird
Come hop, hop, hop;
So I cried: "Little bird,
Will you stop, stop, stop?"
And was going to the window
To say: "How do you do?"
But he shook his little tail
And far away he flew.
