No birds in my garden

[dickens]

I have a good full bird table in the garden which used to be quite busy.For about 3months now I have hardly had any callers.there are fat balls,peanuts and wild bird seed but not even the pigeons are calling.They still visit next door though.I don't have a cat but one does prowl around.I live at the back of a small nature reserve so should really have a good selection of birds.Any one any ideas please.
