[edit] Subspecies

Two subspecies accepted which are sometimes considered full species[1]:

  • T. m. melanopis (Black-faced Ibis)
  • T. m. branickii (Andean Ibis): Paler than nominate, with less ochraceous colouring on breast and neck

With the latest update of Clements checklist, there is now a majority of checklists that recommend lumping these two forms in one species.

[edit] Habitat

Wet grasslands, open grassy and agricultural fields, salt lagoons, arid sandy areas.

[edit] Diet

The diet consists of insects, worms, frogs, salamanders and sometimes rodents. In addition they consume a lot of burrowing larvae. They will also take small chicks and mammals.

[edit] Breeding

Their nests can be found in woodland, on cliffs and in rocky gullies. The clutch consists of two eggs, which are incubated by the female for 28 days. They sometimes nest in colonies with Black-crowned Night Heron
