Greenfinches - where are they?

Last year, I hardly saw a greenfinch in the garden, even through the bad weather they were scarce visitors to the feeders. This year not even a single sighting, even during the RSPB Big Weekend...nothing. 

Has anyone else noticed the reduced numbers or is this an isolated case for my local patch. Goldfinches on the increase, Siskins regular visitors in a group of 6 or so, Chaffinches 20 plus at times and then the Sparrows, oh yes Sparrows everywhere, each family group fighting with each other and in fighting too.
