The Chionis alaba is known as Snowy Sheathbill while some call it Paddy, a part and parcel of the species known as Sheathbill. It is a bird found on land, while it is interestingly the only bird that is land-based in Antarctica.

The Chionis is around 15 or16 inches in length with its wings ranging between 30 to 31.5 inches. Except for their warty faces and that they are pink in color, the Chionis alba, which means ‘Snow White’ is ultimately white as the name suggests.

Range and Population

The chionis Alba is found in Antarctica, Southern Georgia, Scotia Arc and South Orkneys. For the Sheathbills that live so far in the southern region, they usually migrate towards the north in winter times. This bird species breeds within the Antarctic Peninsula, Elephant Island, South Shetland Islands, South Georgia and South Orkney Islands. However, it is also a migrant to Falkland Islands as much as it does not breed there, as well as in Patagonia in Argentina and Fuego in Chile. Other birds are known to wonder towards the North. The Chionis feed on unattended eggs of the penguin during breeding times. Their nests are made of litter, such as dead chicks, guano or bones. They are known to lay about 2-3 eggs although they only raise one chick, while sacrificing the weaker one as food for the stronger chick. They spend most of their time scavenging in between the colonies of penguins. This is mostly because they lack webbed feet and thus they obviously face difficulties in fishing, ending up as scavengers.

Diet

The Chionis is squarely a scavenger and feeds on any type of droppings while stealing chicks as well as taking carrion, seaweed and also small young seals. They forage almost everything within their habitat, mostly among the penguins.

Ecology

While the species is found within seabird colonies, more so among penguins, it is also found among the albatrosses and cormorants and between the seal rookeries and the haul-outs. It also lives among human settlement within the Falklands and it is omnivorous and ultimately feeds on prey from marine, mostly stolen from the penguins around them.

Conservation and Threat

As much as the Chionis Species might meet a restricted range, conservationists do not believe it is within the realm of vulnerability within the criterion of range size. This are measures that range from a distinct kilometer squared and combined with fluctuating or declining range capacity, quality and habitat as well as population size and a lower number of regions or critical fragmentation.

The Chionis Alba population is quite stable and thus the species is not in any way approaching the threat threshold, or a 30 percent decline within three generations or ten years. The size of the population can be small to moderately large although it is not under menace or a continued decline within the specified measures of population trend criterion. This is the reason this bird species has been repeatedly evaluated as of Least Concern.
