A Speckled Feather Visitor

I marched straight out of my bookshelf nest and hopped onto the wide wooden windowsill! Right outside on the glass ledge, a tiny brown sparrow landed with a soft flutter. I pressed my bill right up against the cool glass pane to say a huge morning hello! The sparrow cocked its head, blinked curious little black eyes at me, and pecked three gentle taps against the glass before sweeping away into the autumn air. It left behind a tiny gray downy feather stuck to the sill!
