We describe a new species of storm-petrel, Oceanites pincoyae (Pincoya Storm-Petrel), from the Puerto Montt and Chacao channel area, Chile. The description is based on 1 specimen collected at sea in Seno Reloncavi on 19 February 2011 and 11 other individuals that were caught, examined, and released. The new taxon's foraging ecology and behavioral habits are unique among the southern Oceanitinae, including “mouse-runs” and repeated diving beneath the surface to retrieve food items. Its distinctive appearance includes bold white ulnar bars, extensive white panels to the underwing, and white to the lower belly and vent. Among species of Oceanites, it is unique in showing white outer vanes to the outer two pairs of rectrices. It further differs from all other storm-petrels in having a distinctive juvenile plumage. Morphometrically it is distinct from Oceanites gracilis gracilis (Elliot's Storm-Petrel) and smaller than O. oceananicus chilensis (the Fuegian form of Wilson's Storm-Petrel), having a shorter tarsus and longer middle toe. There also appear to be differences in the timing of breeding and molt between the new taxon and both O. o. chilensis and O. g. gracilis. We estimate the population size of the new species as ∼3,000 individuals.

Resumen

Describimos una nueva especie de petrel, Oceanites pincoyae, del área de Puerto Montt y el canal de Chacao, Chile. La descripción se basa en un espécimen coleccionado en el mar en Seno Reloncavi el 19 de febrero de 2011, y en 11 individuos adicionales que fueron capturados, examinados y liberados. La ecología de forrajeo y los hábitos de comportamiento del nuevo taxón son únicos entre los demás Oceanitinae del sur, incluyendo “carreras de raton” y buceos repetidos por debajo de la superficie para obtener el alimento. Su apariencia única incluye barras cubitales gruesas y blancas, parches blancos extensos por debajo del ala, y vientre bajo y cloaca blancos. Entre las especies de Oceanites, es único en mostrar el vexilo exterior blanco en las dos parejas exteriores de rectrices. Además se diferencia de otros petreles por tener un plumaje juvenil distinto. Morfométricamente se diferencia de Oceanites gracilis gracilis por tener el tarso más corto y el dedo medio más largo, y es más pequeño que Oceanites oceananicus chilensis. También parece haber diferencias en el momenta de reproducción y muda entre el nuevo taxón y O. o. chilensis y O. g. gracilis. Estimamos un tamaño poblacional de la nueva especie de unos 3000 individuos.

The New Zealand storm-petrel Pealeornis maoriana Mathews, 1932 was described from 3 specimens collected in the 19th century. Since 1952 it has most commonly been considered a subspecies of Wilson’s storm-petrel Oceanites oceanicus exhibiting the ventrally streaked “Pealea” phenomenon. There had been no recorded sightings of the New Zealand storm-petrel in over 170 years before Jan 2003. Since then, observations off northern New Zealand of storm petrels believed to be this taxon have been made regularly during the austral summer. From observations and photographs, these birds appeared more similar to the New Zealand storm-petrel than to other storm petrel species occurring in the region. However, confirmation of their identity was not possible without capture. In Nov 2005 one was captured off Little Barrier Is, and 3 more were caught elsewhere in the Hauraki Gulf in Jan 2006. Analyses of detailed descriptions, photographs, and morphometric data of these birds provide conclusive evidence that they represent an extant population of the New Zealand storm-petrel. Our analyses of these data and comparison with the New Zealand storm-petrel museum specimens and 17 other Southern Hemisphere storm petrel taxa (subfamily Oceanitinae), lead us to conclude that this species is distinct.
