Grubs up !

I bought this bird feeder second hand with some money my daughter gave me. Put it together today and filled up the various feeders. The first visitor was ............?

A bloomin' great pigeon but with only the one tray they can sit on at least the whole colony can't land and polish off every last drop of food.

The grubs are of course left over fishing bait which I know the robins and blackbirds love.
