I came second in there RSPB competition and one of the prizes was complimentary membership for 6 months
To be honest there not much going on it seems be much more geared to wedding/landscape photographers and besides a very expensive looking magazine you receive the actual activity in the wildlife section is like tumbleweed,
If you like going to conventions and possibly the mentoring side and they say you can earn qualifications it may be of use?
I haveI talked to a few people when out and about who feel the same, and I know one person who did pay and cancelled after finding a similar experience just not much going on for wildlife side
