Camouflage and colour change: antipredator responses to bird and snake predators across multiple populations in a dwarf chameleon

Abstract: Potential prey are often exposed to multiple predators that vary in their foraging tactics and ability to detect prey. For animals that rely on crypsis to avoid predators, one solution is to alter their behaviour or appearance to maximize crypsis in ways that are specific to different types of predator. We tested whether dwarf chameleons ( Bradypodion transvaalense ) showed different behavioural responses, including colour change, towards multiple predators (bird and snake models) that detect and capture prey … Show more

“…Giurfa et al 1997;Kelber 2005). Studies on predator-prey relationships indicate that prey species as diverse as reptiles, birds and insects are often more camouflaged with respect to chromatic cues than to achromatic cues (Hâstad et al 2005;Théry et al 2005;Stuart-Fox et al 2006). Field experiments on disruptive coloration of artificial moths also suggest that colour contrasts may play a crucial role in achieving protection (Schaefer & Stobbe 2006).…”

“…It has been shown that birds and primates attend primarily to chromatic and not to achromatic cues when searching for fruits (Sumner & Mollon 2000Cazetta et al in press). Furthermore, several studies indicate that prey species are often more camouflaged with respect to chromatic than to achromatic cues (Théry et al 2005;Stuart-Fox et al 2006). For several reasons, chromaticity produced in the UV/blue range of the spectrum might play a special role for passerine birds.…”
