My cycling is and has been limited to England but I get to see a fair bit of wildlife (but I won't try to list them all). I see deer quite regularly, usually solitary or in very small groups (I suspect mother with young) - red deer, fallow and muntjac by my reckoning - once I saw a large group of about 20 fallow deer making their way across the fields, jumping obstacles and squeezing through gaps in hedges - I found that quite spectacular.
At certain times of the year, I seem to do a lot of pheasant herding down the little lanes.
When I used to go out at night a lot, I would see lots of owls, foxes, badgers and bats (in my experience, the badgers try to outrun me and I end up slowing down to give them a chance). I've had a bat hunting in my headlamp beam, flying at the same speed as me and just in front for a short while, after the moths in my beam.
I once stopped on a single track lane to let a grass snake of about 2-3 feet cross the road - I didn't get my camera (phone) out in time to get a picture.
I turned a corner on a narrow lane through some woods as a buzzard was coming the other way round the corner. I think we both gave each other a shock and narrowly missed each other - I felt the wind from it on my face as it just missed my head.
Last week, whilst by the River Alne just outside Alcester, I stopped to take a picture and was just putting my camera away when I noticed a dark animal up the road. Turned out to be a mink - it trotted right past me and gave me a look like it wasn't bothered by me at all. I managed to get a couple of pictures but struggled with my laggy electronic camera with motorised zoom and hunting auto-focus.
