Note: These Challenge Questions coincide with the Spring 2005 Reports Challenge Question #2 From: by way of Jane Duden Journey North <susamel@brounstein.com> Date: Mon Mar 07 2005 - 09:15:35 EST We believe that the male Rubythroated Hummingbird molts because his feathes are worn out and no longer durable. Worn out feathers will not be warm . Dull colored wings are not as appealling to females and are not as durable as colored metalic feathers.
