Free-living organisms must forage and make a series of decisions to optimize energy intake and
minimize costs associated with foraging. Herbivores must make foraging decisions that are affected by dietary constraints. Many plants have high fiber content, low nutritional value, and defenses such as plant secondary metabolites. In response to these defenses, many strategies to overcome costs and maximize the benefits of plant consumption have been evolved. Despite robust literature on herbivory, few studies have investigated how herbivores balance the cost of foraging with other costs, such as reproduction, and how foraging decisions directly affect reproductive fitness. I will present results that explore the relationships and trade-offs between foraging and breeding behaviors including relationships between diet quality, stress, and territory quality on the lek as well as the effects of diet and foraging behavior off-lek on on-lek reproductive behavior and success. Preliminary results indicate that those males that make more optimal decisions while foraging are also doing so on the lek in terms of territory settlement and display effort.
