The other evening I was sitting outside under a tree babysitting our hens. We have only been letting them out in the evening under supervision until we can get a handle on some fox problems (we are working on it).
As I sat and read, a sense of calm came over me, and I was surprised to realize that it was triggered by a little flock of nasty starlings.
Starlings start to flock up this time of the year, and I guess there was just some sort of Pavlovian response that said, yes, fall is just around the corner. The starlings say so.
