Bear, I am not particularly good at it, and also I don't have the budget to travel outside of Southern Africa, and even then not much more than a couple of weeks per year.
My best year so far has been last year, when I got 261 birds, plus another 9 that were of too poor quality for me to want to post (although take note that this forum is not a photographically-orientated one, and some of the other competitors post horrendous photos).
Some of the other competitors regularly get over 600 birds a year!
