This chapter discusses social interactions and the reproductive behavior of horned lizards. It first examines the head-bobbing patterns of horned lizards and analyzes the behavior that follows these initial greetings. It then examines their mating and nesting behavior. It also suggests that climate, elevation, and geography have profound influence on the reproduction of each species of horned lizard. For example, the pygmy horned lizard (Phrynosoma douglasii) and the short-horned lizard (Phrynosoma hernandesi have the widest distribution in cooler northern climates and in high mountain elevations and northern latitudes. They have adapted their reproductive cycles to very short seasons and low temperatures.
