fewer species this year

Ive just finished my hour 8-9 am 29-01-12 and only saw 4 species in my garden this year, 2 Robins, 3 Blackbirds 2 male 1 female a pair of collared doves and a wren.Last year I recall a lot more  and larger numbers, mind you my seed and nut feeders haven't been out this week as I've run out and being housebound not able to get any .I have asked family members to get them for me but they forgot! At least its not been snowing and I've been putting out bread and other odds and ends.Lots of glimpses of other types outside my garden though magpies, feral pigeon's and crows plus of course that ubiquitous grey squirrel.
