I commute about 15 miles each way a couple of days a week in the summer months (whenever it is light enougth). I live in a Cumbrian fellside village and it is hilly twisty, with areas of road two feet deep with water for a good part of winter or covered in snow or ice.
Yesterday after a holiday it really felt like my rides were numbered now as it is getting darker cars have lights on etc. I gave a red squirrel a coronary as it raced up a tree to get away from me and it started me thinking about the things I have seen this year - little owl, red deer, hundreds of beetles crossing the road to get in trees out of the morning sun, hares etc etc.
One evening however I saw an African parrot flying overhead you know the blue/ red & yellow things. They are huge. I nearly got run over as a car driver coming the other way was also watching it and came on to my side of the road.
