Were broad-billed prions from The Snares part of the massive die-off of this species in 2011?

  • South Bay Snares
  • Dead skua prey remains
  • Skuas feeding
  • Broad-billed prion chick, Snares Island. Te Papa

This was one of the key questions that we were trying to answer when four Te Papa scientists – Colin Miskelly, Antony Kusabs, Jean-Claude Stahl and I – set off for the subantarctic Snares Islands in November-December 2013.  The Snares are one of the world’s great seabird islands and broad-billed prions – a small blue-and-white… Read more »

A Te Papa team recently visited the Snares Islands, 105 km south-southwest of Stewart Island, where they completed a range of seabird research projects. The most time-consuming task was a re-survey of the vast sooty shearwater (titi, or muttonbird) population there. Estimating the population size was based on two main parameters – the number of… Read more »

Te Papa’s curator of terrestrial vertebrates Dr Colin Miskelly is researching the life and work of the Canterbury naturalist Edgar Stead (1881-1949). This includes re-taking Stead’s photos from the same photo-point, taking other images to illustrate his diaries, and describing how the ecology and wildlife of each of 11 islands has changed since Stead’s visits….
