Unsorted Wild Birds

Black-faced Sheathbills, aka Lesser Sheathbills or Paddies



The Black-faced Sheathbills (Chionis minor), also known as the Lesser Sheathbill or Paddy, is one of only two species of sheathbills, aberrant shorebirds which are terrestrial scavengers of subantarctic islands.



Dumpy, short-necked, pigeon-like birds with white plumage, black bills, caruncles and facial skin. Measurements: length 38-41 cm; wingspan 74-79 cm; weight (male) 530-610 g, (female) 460-530 g.



Restricted to subantarctic islands in the southern Indian Ocean: the South African territory of the Prince Edward Islands, the French territories of the Crozet Islands and Kerguelen Islands, and the Australian territory of Heard Island. The birds on Heard Island comprise an endemic subspecies, Chionis minor nasicornis.



Coastlines and intertidal zones of subantarctic islands, especially around seabird and seal colonies, as well as the vicinity of human habitation.



Sheathbills are opportunistic omnivores, predators and scavengers, feeding on strandline debris, algae and other vegetation, as well as on invertebrates, fish, seabird eggs and chicks, seal milk, blood, placentas, carrion, faeces, rodents and human refuse.



Loud, high-pitched, strident and staccato calls.



Nests in crevices, caves and under boulders on untidy piles of vegetation and debris from seabird and seal colonies. Clutch usually 2-3 creamy-white eggs, blotched or speckled brown. Incubation period c.30 days. Young semi-precocial and nidicolous; fledging c.50 days after hatching; breeding at 3-5 years.


At risk from scavenging toxic wastes and from introduced predators such as feral cats, but large, scattered range with no evidence of significant overall population decline leads to conservation status assessment of Least Concern.
