Ulva Island bird sanctuary

17 November 2019

The water taxi drops us off at the jetty, and as we walk up to the small shelter where we’re due to meet our guide we’re greeted by a giant cartoon rodent inviting us to check for rats and seeds. It’s a reminder – if one were needed – that we’ve landed in a very special place.

Hint: this is a very special island!

Ulva Island, weighing in at 267 hectares (660 acres, or just over one square mile) is one of the jewels of New Zealand conservation. Here’s what the Department of Conservation has to say about it:

Listening to the bird song on Ulva Island/Te Wharawhara is like stepping back in time, to an era when New Zealand’s bird fauna was still largely intact. This predator‑free island, located in Paterson Inlet/Whaka a Te Wera, Stewart Island/Rakiura, is not only a bird enthusiast’s paradise; it is also one of the few offshore islands with a largely undisturbed podocarp forest. This mature forest distinguishes Ulva from other sanctuaries such as Kapiti and Tiritiri Matangi, which are largely covered in regenerating vegetation.

Cats, possums and stoats – three of the main predators that threaten native birds – have never made it to Ulva, but rats were a big problem. An eradication programme that ran between 1992 and 1997 successfully got rid of them, but constant vigilance is needed to ensure they don’t make an unwelcome return.

Similarly, efforts to keep the seeds of introduced plants off Ulva help protect the primeval vegetation. There are almost no non-native plants here on Ulva.

The trees come in all shapes and sizes

Before we move off into the forest we’re pleased to see an old friend, the weka, searching for insects on the kelp washed up along the beach. He’s intent on lunch, and untroubled by our presence. We’ve seen these flightless birds at several places during our New Zealand travels, although the plumage of those from Stewart and Ulva Islands is a slightly different – chestnut – colour.

We set off on our walk, along well maintained tracks that were first carved out of the undergrowth in the 1880s. Unsurprisingly the bird watching is challenging, as it always is in forests. Bird listening is easy – they’re all over the place, singing their little hearts out – but can we see them? Of course not, the little buggers are keeping their heads down amongst the foliage. All except, that is, the Stewart Island Robin.

Stewart Island Robin

The Stewart Island Robin, or toutouwai as the Maori call it, is small, primarily grey and sports a white breast. It is ludicrously tame, approaching our party fearlessly, hopping between and over our feet. Given its trusting nature and habit of nesting close to the ground it fares badly wherever rats are present, so here on Ulva is one of the few places where it continues to thrive.

That the robins are here at all for us to enjoy is thanks to a reintroduction programme. Following the eradication of the rats, 18 birds were brought in from another population on Stewart Island. These quickly settled in, and numbers have since grown steadily. We find them – or, to be more accurate, they find us – at various points along our walk through the island, suggesting they are now very firmly established here.

Yellow-crowned Parakeet

As we walk on we’re delighted to see some more old friends, kaka, or forest parrots. They inevitably remind us of dear old Lady Kaka, the feisty bird that lives, loves and squawks loudly on the porch of our accommodation on Stewart Island. But there’s another parrot too, or more correctly a parakeet. The Yellow-crowned Parakeet, or kakariki, is a noisy chap who spends most of his time flitting around in the forest canopy. Luckily one drops on to a low-hanging bough for a few seconds, giving Mrs P a chance to fire off a quick shot.

The variety of vegetation is immense

It’s not all about the birds, though. The variety of vegetation, all of it totally unfamiliar to a casual visitor from the UK, is immense. Our guide knows her plants however, and shares her knowledge of bush-lore. Amongst the most interesting things she tells us about is the Muttonbird Scrub Leaf.

Until the 1970s it used to be entirely legal to pluck a leaf from this plant, write a (short) message, whack on a postage stamp and send it through the New Zealand mail. Also, when you’re caught short in the bush, the leaf makes excellent toilet paper. We’re told that there is a similar species found further north in New Zealand which has the consistency of two-ply toilet paper. However down here they do things a lot better: Ulva’s Muttonbird Scrub Leaf is four-ply quality. Oh, such luxury!

South Island Saddleback

But perhaps the greatest thrill of our visit to Ulva Island is to catch a glimpse of the South Island Saddleback. In 1964 this bird was confined to Big South Cape Island, and down to just 36 individuals due to the arrival of rats. Those few birds were moved to pest-free islands, and in due course some were brought to Ulva where they are flourishing. It’s another encouraging example of how, with hard work and sufficient resources, threatened birds can be brought back from the brink.

Ulva is an inspiring place, a hint of what all of New Zealand must have looked and sounded like before humans arrived with their alien species of mammals, birds and plants. In one sense I suppose it’s like a museum, but a living museum, teeming with life, exuberant, vibrant and colourful. It’s most definitely a must-see destination for visitors who seek an understanding of New Zealand’s unique natural heritage.

    It’s good to know that a few refuges remain, but it’s heartbreaking to think about all the birds that have been and are still lost to invasive species (humans included).

      Agreed on both counts. As things stand today, in 2019, humans are both the main problem and the only solution. Let’s hope that compassion and resourcefulness can win out over indifference, greed, ignorance and idleness. Ulva Island gives me cause for hope, but then I read about the other stuff, the devastating impact of plastics on marine life for example, and the slow death of ecosystems as a result of climate change, and despair sets in. I suppose all we can do is lead good, responsible lives ourselves and try, in our own small way, to get the message across to people we’re in touch with in person and online?

    What a wonderful place, and what a shame it has to have such high security protection. If only we weren’t so slap happy about ‘regulating’ populations, chucking pesticides about, introducing pests and invasive species because we thought it would look pretty in the front garden…

      NZ is overrun with species that Europeans (mostly Brits) and Aussies (mostly ex-Brits) thought would look good, taste good or sound good, or just remind them of home. Sparrows, blackbirds, goldfinches, skylarks … New Zealand’s got them all, shipped over in the nineteenth century and released to make themselves at home. Most ironically and shamefully of all, Brits introduced rabbits because they’re good for the pot. They then found themselves overrun by rabbits, so they introduced stoats to control them! Now the stoat, being a clever creature, quickly realised that there was little point in running fast to catch rabbits when it could eat just as well but with much less effort by chasing down the local flightless birds. And thus was born New Zealand’s greatest ecological disaster: the stoat is Public Enemy Number 1 as far as native bird species are concerned. You couldn’t make it up.

        The energy they’re having to expend to clean up the mistakes of the past! You could say ‘they didn’t know any better’ also that they had very little regard for other life forms, but I think we’ve evolved a bit since then. No excuse now for importing ridiculous exotic plants riddled with exotic bacteria and bugs.

        Totally agree. In the 21st century, with all that we know, there are can be no excuses from crimes against the environment.

        There shouldn’t be, and those who deny there is a problem need taping up and dropping in the non-rising ocean.
