we've a number of wildlife rescue centre members in our membership so i'm sure you'll find someone - if you get stuck I'd be happy to do a talk about my work with
Badgers - tho I am more involved with protection and investigation than I am with the animal care side
alternatively I could talk about my life as a warden focussing on a vareity of animal related experience - such as extricating a buzzard from a larsen trap, rescuing a shag from a moored fish net, recapturing an iberian lynx etc etc
I know these arent exactly on target and as i say i'm sure you will find somebody better but if you need me to owt give me a shout by pm.
