Different reactions to aposematic prey in 2 geographically distant populations of great tits

Abstract: Variation in predator behavior toward aposematic prey was frequently studied at interspecific and individual levels, but interpopulation differences have been neglected. Geographic differences in prey fauna offer an opportunity to test their implications for predator behavior. It can be expected that 1) predator populations inhabiting environments with high diversity of aposematic prey are more neophobic than those living in areas where aposematic prey are scarce, and 2) different levels of neophobia jointly w… Show more

“…The chemical defences of these two groups are poorly understood (Lin, ; Wood, , ), but at least some species such as Umbonia crassicornis (oak treehopper) and Platycotis viltata (thorn bug) have striking aposematic colouration and are rejected by lizards as prey on the basis of taste (Wood, , ). Indeed, there is extensive evidence for aposematism in many related families of larger and better studied hemipterans (e.g., frog hoppers/spittle bugs (Peck, ; Thompson & Carvalho, ), stink bugs (Gamberale‐Stille, Johansen, & Tullberg, ; Krall, Bartelt, Lewis, & Whitman, ), milkweed bugs (Skow & Jakob, ), harlequin bugs (Fabricant, Exnerova, Jezova, & Stys, ), and firebugs (Exnerova et al, )). While we have evidence of Habronattus frequently feeding on green leafhoppers in the field, we have never observed them feeding on species with bright colour patterns (pers.…”

“…Prey colour biases could also be shaped by factors other than learning. If a habitat lacks any red prey types, neophobia rather than experience may still drive biases against red (Exnerova et al, ). Similarly, innate biases could explain avoidance of red by naïve predators (Mastrota & Mench, ; Schuler & Hesse, ).…”
