Hi Tico and Eleanor Tico - this is more for your interest, although it's possible that you and Guy have already been in touch. Whilst the "guide" is a good idea, it's relevant for BWPA as they need it more than we do .. Perhaps Paul F knows of this work already? Thanks Debie From: Guy Balme [mailto:gbalme@xxxxxxxxxxxx] Sent: 08 April 2011 05:01 PM To: debbie@xxxxxxxxxxx Subject: Leopard aging test Hi Debbie, We've never met but I've heard lots about your work. I have a favour to ask. I'm trying to compile a leopard aging guide for hunters similar to the one that Karyl Whitman & Craig Packer produced for lions. I don't believe age-based regulations are as applicable for leopards (given they harder to age & the threshold over which hunting has little affect appears that much older) but I still think it's important that we encourage & assist hunters to target older males. I've finally managed to collate enough material from known-aged leopards in the Sabi Sand Game Reserve in South Africa to produce the guide. However, before it's distributed, I'd like to run a short test to assess the accuracy of aging & sexing leopards from photographs. I realise this is v different from doing it in the field but I still believe it's a worthwhile exercise. It will hopefully demonstrate which age classes are more difficult to distinguish, the most suitable photos to use (facial, side profile, or a combination of both), etc. As many leopard hunters now use camera-traps to judge trophy quality, it will at the v least provide information on how best to deploy cameras & appraise pictures. If there is enough buy-in, I would also like to run a follow-up test once the guide has been published to gauge whether it does improve aging ability. The test is split into 3 sections - sexing leopards only (no aging component), aging male leopards using individual photographs, & aging male leopards using paired photos. All of the pictures are of known-aged individuals but I have used 4 age categories for test: 0-2 yrs, 2-4 yrs, 4-7 yrs, >7 yrs. These make the most practical & biological sense. Again, I know there are marked regional differences in the size & appearance of leopards but some of the aging cues are applicable across their range. Is there any chance you can circulate the test among members of the BWMA? I realise there are v few leopards now hunted in Botswana but I'm sure many of the PHs would have extensive experience from the past. To make this meaningful, we will need a decent sample size. The test only takes 15 min or so to complete & I will send them their results (which will be kept strictly confidential) & a copy of the guide if they participate. Pls tell them to respond directly to me at gbalme@xxxxxxxxxxxxx Thanks v much.
