This morning I got back from the barn and the beach with James, got changed, and settled down at the computer to do some work when James leapt up barking, just as there was this godawful noise from the utility room. I ran downstairs thinking it was the well pump or maybe the hot water heater. Nothing. Then the noise came again...sounded like a jackhammer. Couldn't find anything...air in the pipes maybe?? Came back upstairs to find James barking at my bedroom window. Again, the noise. Went back downstairs and outside, following it........
Turns out it was a VERY confused, very young woodpecker pecking at my rain gutter. Bery cheap fix...James chased him away. Good Dog!!!
