There are hardly any birds visiting my garden - October - although I'm still putting out some food for those that are coming. There were probably dozens up till a month ago. I haven't found any dead birds. Anyone else having the same?
(Pardon the Scottish Accent)
I would also add to Linda's very good and informative reply, the autumn so far for many parts of the UK, and I'm presuming you're in the UK, have been extremely mild, so there are still a lot of insects around.
