Possible Costs of Conspicuous Dimorphic Coloration of Hatchling Male Collared Lizards (Crotaphytus collaris): Increased Risk of Predation?

Abstract

I am studying a species of lizards called Eastern Collared Lizard (Crotaphytus collaris collaris). I will be monitoring a single population that is located on the outside edges of Stillwater, Ok. I investigate the abnormal pre-productive coloration of male hatchlings. My main question is if these orange bars relate to the over all fitness of the males.  My study explores the pros and cons associated with hatchlings having these bars based on how predators react to these bars. Since the bars stand out against the lizards natural habitat I assume this will lead to a heavier predation rate by Coachwhip snakes (Masticophis flagellum). My hypothesis is that Coachwhips will predate the male hatchlings with vivid orange bars more than drab colored hatchlings. These bars are important, because they show themselves before the hatchling reach an age of production.  Their appearance, before productive age, is highly confusing since animals should not display sexual dimorphism during non-sexual years. Dimorphism is the occurrence of gender specific formations found in one species.
