Black-hooded Sunbeam Aglaeactis pamela

  • Order: Caprimulgiformes
  • Family: Trochilidae
  • Monotypic
  • Authors: Thomas S. Schulenberg and Carolyn W. Sedgwick



There is little information on the behavior of Black-hooded Sunbeam. This species forages and perches at all heights, from low to high (Parker et al. 1996). This sunbeam sometimes perches on a flower while gathering nectar, and, like other species of sunbeam, typically holds the wings aloft for a few seconds after landing on a perch (Fjeldså and Krabbe 1990).


There is no information on territoriality or home range size for Black-hooded Sunbeam.

Sexual Behavior

Little information. Black-hooded Sunbeam presumably is polygynous, as are most if not all species of hummingbirds (Schuchmann 1999: 509).

Social and interspecific behavior

Black-hooded Sunbeam usually is solitary, as is typical of hummingbirds.


No documented reports of predation on Black-hooded Sunbeam?
