Footballing Wood Pigeon?

The woodpigeons in my garden are so greedy I have to keep chasing them off, otherwise the other birds wouldn't get a look in.

Yes, they and the doves just sit in the feeding tray until it's all gone. I have one of these dome feeders, set so the bigger birds can't get in but the food hasn't been touched in over two weeks.i don't understand it.at my old house, we used to get tits, sparrows dunnocks,robins and very occasionally, goldfinches in it. I keep moving it but it makes no difference where it is.
