Juvenile Collared Lizards Adjust Tail Display Frequency in Response to Variable Predatory Threat

Antipredator behavioral tactics have evolved in phylogenetically diverse animal clades and often involve prey initiating conspicuous display patterns when encountering potential predators. Using detailed behavioral observations in the field, we report the first description of conspicuous tail displays in juvenile collared lizards ( Crotaphytus collaris ), a species that does not have tail autotomy. When approached in the field, lizards gave four...
