White-rumped Tanager Cypsnagra hirundinacea

  • Order: Passeriformes
  • Family: Thraupidae
  • Polytypic: 2 subspecies
  • Authors: Ashley True and Kevin J. Burns

Priorities for Future Research

Compared to other tanager species, the White-rumped Tanager is relatively well-studied. Isler and Isler (1999) summarize the biology of the species, including unpublished data from T. A. Parker and A. Negret. Santos (2008) studied the reproductive behavior of this species, including its cooperative breeding. Studies by Ragusa-Netto (1997, 2000, 2002) investigated this species foraging behavior and its role as a sentinel in mixed species flocks. Despite all this research, additional studies are needed, including studies investigating the details of their vocalizations, territoriality, courtship, and demography. Although the conservation status of the White-rumped Tanager is rated as of Least Concern, very little is known about the global population size and potential effects of human activity on population trends. Studies of the genetic relatedness of helpers in the same group would also help clarify the degree to which helpers are related to other members of the group. The two subspecies show marked differences in plumage; intraspecific genetic studies would indicate whether these differences correlate with significant differentiation at the molecular level.
