Buff-necked Ibis which has white in the wing and a buffish breast
Distribution
South America: found in Ecuador, coastal Peru, Bolivia, northern Chile and Argentina south to Tierra del Fuego.
Taxonomy
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.
Habitat
Wet grasslands, open grassy and agricultural fields, salt lagoons, arid sandy areas.
Behaviour
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.
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
