Totipalmate, or Fully Webbed Swimmers 



The hooked bill that helps hold a slippery fish secure ; the 

 iridescent black and brown plumage, which is the same in both 

 sexes; and certain special featherings of a temporary character 

 that are worn during the nesting season only, are among the 

 most noticeable characteristics of this family.
