Well the old favourites are Autumn woods, especially places such as Burnham Beeches, the New Forest, the Forest of Dean and the Caledonian Forests of Scotland. Old buildings such as Windsor Castle are nicely framed by Autumnal trees. Darter and Hawker dragonflies are still abundant. Fungi are my obsession, and most people like pictures of Fly Agarics and Death Caps. I don't think you can go wrong with a nice colourful group of mushrooms. The season is starting and usually peaks in October, though for the last 4 years or so there has been a massive collapse in numbers.
Anyone looking for some lovely fungi should check out fallen trees. Also if you live near some downs, such as the South Downs, or in the wilds of Scotland, then take a walk over unfertilised grassland, and you might come across beautiful wax caps, which can be bright shades of red, orange, green, yellow, white and purple.
Come Winter I am usually moaning about the dark evenings and the miserable cold days. I guess Winter is a time for Winter birds such as Goldeneye and Fieldfare. But you need a big lens for that and most of use do not have such a thing. Yes size does matter when it comes to birds. [No sniggering in the back row.] If there is frost, then hoar frost can make the mundane come alive, and snow can create lovely black and white scenes. I'd still rather be in Florida.
I think Don has the right idea: find a shed to hibernate in.
