Molt is an important avian life history event in which feathers are shed and replaced. The timing, duration, seasonality, extent and pattern of molt follows certain strategies and this book reviews and describes these strategies for nearly 190 species based on information gathered from a 30-year study of Central Amazonian birds. Most species accounts are illustrated with several color photos focusing on wing and tail feather molt, molt limits, and how to use these patterns to accurately age birds.
