We do also have a bird table and do put sun flower seeds on there and they do go, but I've not seen what has been eating those. And the feeding station is out in the open away from any big trees or shrubs so I don't think that is the issue. Maybe it is too close to the house and needs to be moved further down the garden? Only issue then is we won't be able to easily see what's at the table from the sofa! Time to buy some binoculars!
