help stopping a sparrow hawk killing feeding birds

We have between 20 and 50 birds coming to our various feeders every day- fantastic to watch, but this number has attracted a sparrow hawk, who now comes every day to grab its own meal.  This has included chaffinches, gold finches, three kinds of tit, doves.... Infact, basically anything except the wood pigeons I would be happy for it to kill and drag off.  We have now moved the feeders to different parts of the garden, under trees, etc.  The sparrowhawk now just makes a circuit of each area, flying right into the bushes and branches to grab its prey.  Please can anyone advise what we should do?
