Curtin University’s Dr Bill Bateman and Murdoch University’s A/Professor Trish Fleming say their findings support the hypothesis that while increasing the frequency of attack, brightly-coloured tails divert predatory attention away from the head and body, ultimately increasing a lizard’s chance of survival.

To test the theory, they created 48 models of a scincid lizard, half of which were coloured all brown, and half given blue tails.

Pairs of blue-tailed and all-brown lizards were placed in 24 locations, with pairs 300 metres apart, and individuals 25 metres apart, in semi-open conditions on white sand or leaf litter.

Over a week, the researchers assessed damage and damage location daily, recording attacks at 23 of 24 locations, with 65 incidences in total, 60 of which were attributed to birds.

The researchers found that all-brown models suffered an attack to the tail only twice, while blue-tailed models lost their tails on 11 occasions.

The all-brown models were also more frequently attacked on the head and body, which would likely be fatal for a real lizard.
