Feeding Blackbirds

Hoping for some advice from those more knowledgable :)  I've had blackbirds nesting my garden for the last couple of years and I'd like to feed them through the winter.  I have been scattering food on the ground for them but the pidgeons get to it first!  Is there any kind of feeder big enough for blackbirds that would be diificult for pidgeons to use?

 

Thanks, all!
