Sparrow hawk

Hi everyone, I’m looking for some help.  We have a really active bird community in our garden. Lots of different species. We live next to open farm land, our house is bordered by a large very high hedge and trees. Our bird feeder in the front garden is under a very large, wide spread oak tree. However, over the last few days we seem to have a sparrowhawk visiting and taking some of the birds. Young starlings and a blackbird. It lands in the garden quite brazenly. We have a great love for birds of prey and all birds but how can we deter this sparrowhawk. Watching the garden birds is one of our favourite things. Can anyone suggest anything. Thank you.
