Q.Holly bushes and birds
Small birds are eating the holly bushes. They come and eat through the day but do not nest in the bushes. 1 holly has died and cut down to the roots. There was no sign of insects. What can I do to keep the birds away?
It is unusual for birds to eat a significant amount of plant foliage, although many birds will eat holly berries. They may have been looking for insects (and maybe they ate them all so you don't see any now). Possibly they were looking for bark or twigs to use as nesting material. Many mammals will eat shrubs, including the leaves and twigs, and mighttake of bark.
You can protect your bushes with netting if you do think it's birds that are doing the damage.
