Genus DENDROCYCNA. 



The genus Dendrocycna, or Dendrocygna, as most of us would 

 probably still prefer to call it, contains our two widely-known species of 

 Whistling Teal as well as seven others, some of which are found in 

 every continent except Europe. 



Whistling Teal are amongst the few Anatidce who perch constantly 

 on trees and also breed on them. The sexes are similar in plumage, 

 though the female is often slightly smaller than the male. Many sys- 

 tematists used to consider that they were allied more to the Anserince 

 than to the Anatince, and in many ways they do clearly approach the 

 former, more especially, perhaps, in the formation of the legs and bills. 



They are non-migratory ducks, or only so in a very local way.
