Abstract
Serum calcium levels were analyzed by atomic absorption spectrophotometry during different stages of development of the Red-winged Blackbird (Agelaius phoeniceus). The effects of the reproductive cycle, growth, and soil calcium on mean serum calcium levels in this species were analyzed as were the effects of mean serum calcium levels on eggshell thickness, hatchability, and egg production.
