Some things just don’t seem to go together. Peanut butter and tuna fish. Flip-flops on a treadmill. And hearing a catbird when it is 25 degrees and snowing during a New England winter.

I mentioned in last week’s column that I had seen a gray catbird during a recent bird walk. I returned to the same spot several days later. This time, snow was falling all around, painting the beautiful landscape in a covering of pristine white.
