Hazel Catkins in October?

I found these Hazel Catkins (Corylus avellana) in the garden today. Most surprising to see them in October. Although they had not fully opened, I would not normally expect to see them until January or February. Strange things are happening with the seasons.

It was a busy day for wildlife today. There have been a least a dozen pheasants around and when I went to have a look at the pond I disturbed a heron and two mallard ducks.
