In late March 2015, a crabeater seal swam up the Hutt River (which flows into Wellington Harbour) and died. It was a remarkable occurrence – the crabeater seal is an Antarctic species rarely recorded in New Zealand – but no-one realised at the time that this was precisely the place in New Zealand where a… Read more »

A glimpse of ancient Mauritius: Ile aux Aigrettes, restoration island

I first heard of Ile aux Aigrettes at a conference on island pest eradications held in Auckland in early 2001. A delegate from Mauritius spoke about a failed attempt to eradicate Indian musk shrews from the 25 ha island, which had already been cleared of feral cats and ship rats. The island next registered in… Read more »

Once were dodos

The dodo is the world’s most famous extinct bird. Its quirky appearance makes it instantly recognisable in popular culture, including in classics such as Lewis Carroll’s ‘Alice’s Adventures in Wonderland’ and the animated short film ‘Ice Age’. One of the reasons it is so well known is that it is considered to be the first… Read more »

Deep science

Our return voyage on the Marion Dufresne was very different from the voyage south. The first voyage was for logistics resupply, and delivery (and uplift) of personnel, plus we had twelve fare-paying tourists on board. The voyage back was an oceanographic survey voyage. There were a similar number of passengers on board (47), but more… Read more »

The purpose of our visit to Ile aux Cochons* was to undertake a pilot study of the foraging ecology and at-sea distribution of South Georgian diving petrels (’jojos’) to compare with the closely related (and similar-looking) common diving petrels (’plon plons’) that we had studied on Ile Mayes the previous week. The two islands are… Read more »

Very rare indeed: a Malawian dance garment

Witchy tale In 1936, the Dominion Museum was given a gift so rare and strange that it made the news.  Described in the Auckland Star and in museum records as a “witch doctor’s outfit”, the garment was subsequently displayed for many years in the Buckle St building that opened that same year.   During an… Read more »

The petrels of Ile Mayes, Iles Kerguelen

Isles Kerguelen harbour an astonishing diversity and abundance of seabirds, with 33 breeding species. We had seen breeding colonies of several of the larger species on Grand Terre, but Mayes provided a taste of what the islands would have been like before their discovery – and the introduction of cats, rats and rabbits in particular….
