Who’s knocking?!

cabin-life-049a.JPGI was watching the morning news when I kept hearing a tapping.  At first I thought it was someone tapping at my door.  Then, I thought, “Geez, is there a squirrel in the house?”  Taking a look around, I found where the sound was coming from; a robin hitting the bedroom window; still doing it as I write!  It flies up to it and taps; I don’t see that it’s causing itself any harm.  What I’ve concluded is that it’s mating season and he’s looking for a mate; the reflection in our windows!  Or, he could be fighting off a suspected rival!  Only theories!  If looking for a mate, he just might be a lonely robin!  Roger
