Although our consulting detective said the likely culprit was a screech owl, Record readers had no shortage of other suspects.
* Crows: “This year our backyard had 3-4 Crows that were very disruptive to our bird population and nest/bird destructive. They not only grabbed eggs from various bird nests but on at least one occasion brought just “the head of a robin” to our birdbath,” writes G. L. of Woodcliff Lake.
