scientific name

Hydropsalis albicauda
status

 

HYDROPSALIS ALBICAUDA   (J.F. GMELIN, 1789)

Definition

Previously Caprimulgus cayennensis albicauda   . It is elevated to full species status. It is the sister species of H. cayennensis   .

Diagnosis

Very similar to H. cayennensis   , a small, grey-brown nightjar with a broad tawny collar, a white throat patch, and conspicuous white colouring on wing and tail feathers, noticeably more than in H. cayennensis   .

There is over 1.3% divergence in ND2 sequences between H. albicauda   and H. cayennensis   .

Comments

Genetic evidence in this study supports splitting H. cayennensis   into two separate phylogenetic species ( Fig. 7 View Figure 7 ). The subspecies H. a. albicauda   , H. a. apertus, and H. a. insularis together form the phylospecies H. albicauda   , whereas individuals belonging to the subspecies H. c. cayennensis   and H. c. leopetes remain as the original nominate species Hydropsalis cayennensis   . The status of the subspecies manati is unresolved.
