Many lizard species use caudal autotomy to escape entrapment. Conspicuous coloration may increase the likelihood of b.ing attacked, b.t if that attack can b. directed towards the autotomous tail this may ultimately increase the chances of the lizard surviving a predatory attack. We tested the hypothesis that b.ightly-colored tails function to divert predatory attention away from the head and b.dy using pairs of b.ue-tailed and all-b.own clay model lizards. Predatory b.rd attacks on the 24 b.ue-tailed models occurred sooner （P = 0.001） than attacks on the 24 all-b.own models, and over 7 days b.ue-tailed models were attacked more often than all-b.own models （P = 0.007）. b.ue-tailed models were, however, more frequently attacked on the tail than other parts of the b.dy （P 〈 0.001）, while all-b.own models were more frequently attacked on the head and b.dy （P = 0.019） which would b. more likely to b. fatal for a real lizard. Our results suggest that models with a b.ue tail were more conspicuous than all-b.own models, attracting attacks sooner and more often, b.t that the attacks were predominantly directed at the tail. It is b.tter for individuals to b. attacked unsuccessfully many times, than successfully just once. Having a b.ightly-colored tail may, therefore, act as a ＇risky decoy＇. Despite increased conspicuousness, a b.ue tail increases the likelihood that the lizard would b. ab.e to effect escape through caudal autotomy rather than b.ing grab.ed b. the head or b.dy [Current Zoology 60 （3）： 333-337, 2014].
