Taxonomy

Subspecies

Four subspecies are recognized[1]:

  • S. r. uropygialis:
  • S. r. decolor:
  • S. r. aequalis:
  • S. r. ruficollis:

Habitat

Open areas and forest clearings, especially near water. Generally below 1000 m.

Behaviour

Breeding

They nest in cavities such as holes in banks or walls, or disused kingfisher and jacamar nests. These cavities are lined with grass for the clutch of 3-6 white eggs. They are incubated by the female for 16-18 days requiring another 13 days to fledging.

Diet

Their diet consists of insects such as flies, beetles, bugs and flying ants. They generally feed alone or in small groups.
