We have this Barberry shrub that we leave a birdbath under. The Barberry has thousands of thorns on it so it acts as protection for the smaller birds. It is a great spot for the chipmunks to get some water as well. This time of year, as the leaves fall and between water top-ups, there is an interesting mix of colours and textures. The Red of the barberries, in particular, stand out amongst the others.
