Remember that phrase? I say it every time I see an ordinary plain jane (or joe) brown bird. Now, I love my sparrows, so a "how now brown cow" greeting is a term of endearment.
Look at his plump little birdie body...
Isn't he the cutest? Well fed indeed! When he realized a human was taking his picture, he became timid and flew in the pine. Maybe he's a birdie celebrity and doesn't want me to sell his picture for millions to the National Enquirer?
Or...maybe not. He's still cute at a distance. He still thinks I'm weird.
