Fieldfare bully

One of the fieldfares in our garden has established himself as a "fleldmarshall", attacking any blackbirds, and sometimes others,  which try to land.

We are very fond of our blackbirds.  Is there anything we can do to stop this one bird hogging the food we put out in these desperate conditions?  Even the food on the tables is denied the others by his aggression.
