Mammal Society claims bells on cats do not save birds.

“Bell wearing cats seem to kill fewer mammals although bells apparently offer little protection to birds. The modern generation of sonic collars appear to be the answer here. A survey carried out by the British Trust for Ornithology showed that CatAlert, a sonic collar which emits a regular signal, made a significant difference to cat predation on birds. Indeed their figures indicate that the numbers of birds killed by cats wearing one of these devices, fell by 65%.”   See
