Don't go expecting any help or advice from anyone on here though. It's all about bragging.
This and the previous years' threads have always been about two things:
1. sharing information, which unlike bird information is scarce, unadvertised by the authorities - witness the year that RSPB Saltholme had Weasels breed in their reserve centre and never thought to put it on their website - and eratic even for rarities.)
2. Celebrating mammals - principally British, because that's where most of us are based, but increasingly with contributions from elsewhere e.g. crazyfingers over in the USA.
If you see it as bragging, well, bad luck. When I read that Mark or Jos or anyone else has had a coup, I think great for them - and then usually, how do I manage the same thing? I also probably ask them for help. Of course, a lot of that action occurs via PM or phone, so doesn't appear on here till later.
Anyway, if you want to see mammals and have a question, we will try to answer it: if you want to join in, feel free: if your post is typical then you may feel more at home in Rarities on the Audouin's Gull or Night Parrot threads.
All the best,
John
