Artificial bird nests, external validity, and bias in ecological field studies

2004-06-01

Abstract excerpt

We review an increasingly commonly used experimental approach in avian ecological studies that typifies the difficulties of maximizing two major components of experimental design: internal and external validity. Avian ecologists estimate reproductive success by measuring the rate at which nests in specified treatment groups fledge or fail. Because real bird nests are time‐consuming and difficult to find and are ra...
