Our nut feeders seem to attract larger birds in the main like pigeons and collared doves. We have lots of trees and other cover in the garden and nearby.
Every morning at much the same time we get jackdaws on the bird table. We have red legged partridges in the road most days and we have even had mallard ducks in the garden.
