Snowy Sheathbill (Chionis albus), Spigot Point, Antarctica

Snowy Sheathbill Rodrigo Tapia

Observed by a lone Chinstrap, a Snowy Sheathbill, Chionis albus, looks for food surveying a Chinstrap Penguin colony at Spigot Point in the Antarctic Peninsula. Distantly related to plovers, snowy sheathbills get their name from the horny plates that conceal their nostrils at the base of the bill and are the sanitation patrol in Antarctica, feeding on any organic debris they may find, like empty egg shells, dead chicks, and even penguin droppings, which being composed mainly of half-digested krill, are quite nutritious to them.


Observada por un solitario Pingüino de Barbijo, una Paloma Antártica, Chionis albus, inspecciona una colonia de pingüinos en Punta Spigot, en la Península Antártica, buscando alimento. Parientes lejanos de los chorlitos, las palomas antárticas, (que no están emparentadas con las verdaderas Palomas, orden Columbiformes), y cuyo nombre en inglés "pico envainado" hace referencia a las placas córneas que cubren las narinas u orificios nasales, son la patrulla sanitaria antártica y se alimentan de cualquier residuo orgánico que puedan encontrar, como huevos vacíos, polluelos muertos e incluso guano de pingüino, que al estar compuesto principalmente por krill semi-digerido, es bastante nutritivo para ellas.
