Summary Introduction

To review:

The costs and benefits, which shaped the behavior of male redwing blackbirds to prefer marshes to build nest and upland meadows for feeding.

Introduction:

The cost and benefits approach explains that an animal has to spend its time and energy based on its requirements. When demand for food is less or food is abundant near its habitat, then energy or cost spent for foraging is less compared to the food, which is located far away from its habitat. The cost or energy spent for foraging should balance the benefit obtained, which includes food, habitat, and territory maintenance for mating and reproduction.
