I would get the local pair of robins nest in the Ivy on the fence, even blue tits in their nest box close by thou I,m not sure if they liked one anothers company thou or one nested one year and thee other did,nt in that order, but the cats that come through the garden now stopped both of those species nesting to find safer confines, I enjoyed Watching the robins nesting and blue tits plus rearing of their young, after such birds as hedge sparrow and blackbird were robbed of their young by crows and magpies mainly magpies, just after 2000 I had a pair of song thrush nest in early march after about a week a carrion crow took the eggs, not forgetting the squirrels, but with the cats as well any successful birds deserve a gold star in breeding success luckily there are some.
