DEKDllOCYCNA FULVA. 93. Genus DENDROCYCNA. The geniTS Dendrocycna—or Dendrocygna^ as most of us would probablystill 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 continentexcept Europe. Whistling-Teal are amongst the few Anatida3 that perch constantlyon trees, and also breed on them. The sexes are similar in plumage,though the female is often slightly smaller than the male. Manysystematists used to consider that they were more closely allied to theAnserinse than to the Anatina^, and in many ways they do clearlyapproach the former—more especially, perhaps, in the formation of thelegs and bills. They are non-migratory ducks, or only migratory in a very local way. Key to Species. a. Upper tail-coverts whitish, sometimes marked Mith black . D. fulva. b. Upper tail-coverts uniform chestnut D. javanica.
