Bird Feeder Invaders

I know Pigeons are birds too but the bird feeder is usually frequented more by the smaller birds, mainly sparrows.
It was quite exciting for Hendrix, Buddy and Ruby (she visited today too) when the large Pigeon started flapping on the feeder trying to keep it's balance. 
Then the squirrel arrived. The feeder is very close the little conservatory and we were all standing watching them invading the feeder. Didn't bother them at all.
