To most observers, molt seems an overwhelming subject. But birders use many aspects of molt more than they realize to distinguish juvenile birds from adults, to pick out an individual hummingbird from among dozens visiting a feeder, and much more. For those whose interest goes beyond simply identifying birds, questions such as What triggers molt to start? How fast do feathers grow? and How long do they last? offer a fascinating window into the lives of birds. Put plainly, molt relates in some way to everything a bird does, including where it lives, what it eats, and how far it migrates.
How many feathers does a bird have? Do birds sleep while in flight? Why do Blue-Footed Boobies have blue feet? How do migrating birds know where to go and how to get there?
