The neighbors probably refer to Mr/Mrs Rockhead as the ***-damned Crow People. One crow is bad enough, dozens cawing early in the morning or in the evening every day is torture.
When my Dad was in his last years and I came to visit him I noticed that there was a shopping plaza to which scores or hundreds of crows flocked every day around sundown. I don't know what drew them there. The parking lot was
covered with their crap.I imagine they were not exactly quiet, either.
Since crows are carrion birds, I wonder whether "crow people" has a cultural meaning less complimentary than MM realizes.
