Unique to New Zealand, the hoiho, or yellow-eyed penguin, is one of the world’s rarest penguin, so it’s exciting to see that chicks are on their way!Continue Reading...
By Wayne Beggs, Biodiversity Ranger in Akaroa.
We’re fortunate to have some passionate farmers, Mark Armstrong and Francis Helps, who love the local wildlife and who have been the driving force behind protecting the penguins on Banks Peninsula. They had grown up with penguins and were used to seeing them around and they became very concerned when numbers started to seriously decline in the nineties.
Mark and Francis didn’t muck around and bought their own predator traps to try and control the ferrets, stoats and feral cats that were decimating the local little blue and yellow-eyed penguin colonies.
Mark and Francis soon realised that they needed some help and sought support from the local DOC rangers. DOC ranger Robin Burleigh stepped in and added additional trap lines as well as assisting with monitoring the penguins.
Pōhatu is now home to the largest mainland little blue penguin colony (over 1200 pairs last count) in New Zealand and yellow-eyed penguin numbers are starting to creep back up.
A local vet, Susan Shannon, has volunteered her time to help with nest searching, mico-chipping penguin fledglings and providing emergency care for injured or sick penguins.
There are also two passionate volunteers, Thomas and Kristina, who really love penguins and put a lot of time and effort into caring for under weight, sick and injured penguins.
It’s thanks to the fantastic effort of all these people and organisations that the penguins on Banks Peninsula have a bright future.
Sometimes our native species have it tough out there in the wild. This year large numbers of yellow-eyed penguin/hoiho chicks – natives of coastal Otago – have had a particularly challenging first few months of life.
There are often a few that are abandoned by their parents or aren’t well fed, and need to be removed from their nests. But this year a late breeding season and lack of fish to eat has meant a large number of chicks have gone hungry and many have died.
Fortunately, around 80 of these chicks and juveniles are now in the care of Penguin Place.
Penguin Place is a privately run conservation effort and tourism operation, funded through the guided tours they conduct. This project began in the mid 80’s as a family-run conservation project and nature tourism experience. They now carry out a range of conservation work including a research programme, trapping predators, providing safe nest boxes, restoring a stretch of coastline to prime penguin habitat, and rehabilitating sick and injured penguins in its penguin hospital.
Throughout the breeding season, a small team of DOC rangers and volunteers monitor the penguin nesting grounds, conducting health checks of the chicks to make sure they are well fed and gaining weight.
Those that are showing signs of starvation or other ailments are removed from the nest where needed and taken to safe havens like Penguin Place till they fatten up and are ready for release.
Feeding 80 hungry beaks is a big job. It takes two keepers three hours twice a day to hand feed all of the penguin hospital’s current patients – and they’re consuming up to 80 kilos of fish per day! Plus, because they’re still growing, these young patients need fish that’s full of protein and other vitamins, preferably small whole fish with blood, guts and bones.
Thankfully some generous partners have come to the aid of Penguin Place this year. Talleys Nelson contributed an emergency supply of one tonne of pilchard; and seafood company Sanford Limited has just agreed to provide an ongoing donation of up to six tonnes per year.
DOC doesn’t run its own facilitates for providing the specialist care that’s needed to rehabilitate sick or injured wildlife. We work in partnership with a number of specialist organisations like Penguin Place, who have permits from DOC to care for native species. These organisations play a really important role in conservation. So next time you’re in Dunedin pop by, join a tour or make a donation, and show your support.

Using a band or ring has been vital to the monitoring and conservation of birds for more than 100 years. Yellow-eyed penguins were first fitted with leg bands as part of a landmark population study by schoolteacher-biologist Lance Richdale in the 1930’s.
Unfortunately, leg bands proved to be difficult to read and also caused some injuries so, by the late 1950’s, flipper bands became the standard for marking penguins.
The current banding programme for yellow-eyed’s started in the 1970’s and has enabled the monitoring of penguin survival (to a ripe old age of 24 years) and allowed researchers to know the age and history of the individuals at the focus of their research.
Flipper bands are not without problems. They decrease the underwater efficiency of the bird and, particularly if poorly fitted or maintained, can cause feather wear and injury. Alternatives to bands have been explored and one under investigation at the moment is the use RFID tags of the same type used in dogs and cats. While safe and long-lasting, they do have the downside of requiring electronic readers to find out if a bird is marked and who it is.
Whichever method used, it is important to ensure that those applying the tag are doing so correctly in order to minimise the risk to the bird and maximise what we learn as a result. Penguin chicks get tagged just before they go to sea and I recently took the opportunity to join DOC staff, Yellow-eyed Penguin Trust and Massey University Veterinary students and oversee the tagging of this season’s batch of chicks on the Otago Peninsula.
Assisted by volunteers willing to crawl through flax, gorse and nettle, we visited several sites, going to nests found earlier in the season, before locating and capturing the chicks. Bags are used to restrain the birds while they get weighed, measured and tagged before being released back at their nest site. The weight tells us how good the food supply is (5-6 kg is the normal range) and measuring the head and feet of the chicks gives us an indication of the sex – the males are slightly larger.
Also along for a day was Jeff Corwin of “Animal Planet” fame, filming for the third series of “Ocean Mysteries”. Jeff, trailed by his camera crew, enthusastically crawled through the shrubbery, helping capture and measure chicks. Later in the day he assisted researcher Dr Thomas Mattern with the retrieval and deployment of GPS/dive loggers attached to the parents of some of the chicks we tagged as part of a long-term project looking at where the birds feed.
The opportunity to assist with this work, and spend a few days on the beautiful Otago Peninsula in no less than spectacular weather, was very much worth the being stung by nettle, scratched by gorse, bitten, beaten and pooped on by penguins.
Since my visit some 57 adult yellow-eyed penguins on the Otago Peninsula have died suddenly, possibly due to a marine biotoxin. Birds found dead on the beach have been identified by their tag, enabling rangers to locate the nest and keep a close eye on their almost-fledged chicks. Understanding how the penguins encountered the bio-toxin will be helped by the GPS and dive logger data.
Come behind the scenes and into the jobs, the challenges, the highlights, and the personalities of the people who work at the Department of Conservation (DOC).
Today we profile Dean Nelson, Programme Manager – Biodiversity Assets.
Name: Dean Nelson.
Position: Programme Manager Biodiversity Assets, Twizel Te Manahuna Area Office.
What kind of things do you do in your role?
I primarily manage the staff and the resources involved in undertaking the Biodiversity Assets programmes in the Twizel and Aoraki Areas. The key one is the kaki/black stilt recovery project and the associated Tasman predator control programme, but there are numerous others involving plants, fish, lizards and invertebrates. Examples include the delightfully named ‘fish guts’ plant (yes it smells), a fish only found in the Mackenzie Basin called bignose galaxiid (it has a bulbous ‘nose’) and the recently rediscovered knobbled weevil which hadn’t been seen since the 1920s.
Occasionally I still manage to get out in the field when the team needs someone to help out with bird surveys or something similar. I also enjoy doing a bit of fish work where we are having some excellent results with using weirs as trout barriers to protect the bignose and lowland longjaw galaxiids.
What is the best part about your job?
Working with some incredibly dedicated people who never stop trying despite everything that gets thrown at them. Also the chance to work with some really cool species and visit some stunning places.
What is the hardest part about your job?
Dealing with some of the decisions being made by people further up the line who seem to have a relatively limited grasp of the reality of operating at an area level.
What led you to your role in DOC?
I did the old Parks and Recreation Diploma at Lincoln College (now University) and got a job as a Park Assistant at Makarora where I had spent some of my practical year. Not long after I was offered a ranger job at Mount Cook National Park – this was back in the Department of Lands and Survey days. After about seven years of doing all sorts of stuff, I shifted to Dunedin in the middle of the 1989/90 yellow-eyed penguin population crash and got thrown into hand rearing orphaned chicks which led to the species management work I had always been keen to do.
What was your highlight from the month just gone?
A trip to Whenua Hou/Codfish Island to resurvey the yellow-eyed penguin population which is declining for some reason. This is my fifth trip to the island for penguin work and it is a very special little haven for biodiversity. I’ve been fortunate to have a few kākāpō encounters, including having Sirocco do his thing on my head—a painful experience. Have also met and worked with some special people down there.
I wrote a diary (probably should call it a blog or something these days) of this trip which was organised by the Yellow-Eyed Penguin Trust.
The rule of 3…
- My family.
- Getting into the outdoors, walking, tramping, hunting, mountain biking, fishing …whatever it is as long as it’s away from built up areas.
- Holidays which generally involve the above two. I think it is really important to give the kids adventures and experiences that they will remember and treasure.
3 pet peeves
- Idiots who think that it is entirely appropriate to take their 4WD wherever they can, regardless of the damage it causes or the impacts it has on wildlife.
- So much of our beautiful Mackenzie Basin disappearing under pivot irrigators.
- The habit/fashion (whatever you want to call it) that people have of wearing their pants at half mast, exposing undies, boxers and/or bits of their anatomy that shouldn’t be seen.
- Tasman Bay scallops fresh out of the water and quickly fried in a wee bit of butter – melt in your mouth, but unfortunately a bit of a distant memory now!
- Crunchy peanut butter and honey, spread thickly together on warm toast.
- Good quality boutique brewery beers – we have got some stunners down south but sadly, Emersons has sold out to Lion. Hopefully it won’t affect the quality and variety of the beer!
3 favourite places in New Zealand
- Totaranui – I holidayed there as a kid for many years and we are now going back as a family.
- Nelson Lakes – my tramping playground as a teenager. Beautiful valleys, easy tops and the best shingle screes to run down anywhere in the country.
- Any backcountry hut at the end of a hard day’s tramping with the trusty pit laid out on a bunk and a brew on.
Favourite movie, album, book
- Movie: showing my age here—Butch Cassidy and the Sundance Kid. A classic.
- Album: Pink Floyd—Wish You Were Here
- Book: there are heaps of books which could fit the bill however, for someone who has done a wee bit of climbing, an excellent read is ‘Savage Arena’ by Joe Tasker. He delivered the manuscript of this book on the eve of his departure for the British Everest Expedition 1982 where he lost his life. A dramatic tale from a guy who lived life on the edge. “Every step was dogged by a presentiment of catastrophe, as if, out of the mists above, a white wave of death would engulf us.”
Deep and meaningful…
What piece of advice would you tell your 18 year old self?
Get out and do it—you are a long time old and decrepit or even worse—dead.
Who or what inspires you and why?
Our rangers. They are our unsung heros at the bottom of the heap, paid peanuts but they do some stunning work.
When you were a kid, what did you want to be when you grew up?
As a kid, the usual list of suspects, but then in the third form at college, a mate and I wanted to be marine biologists. He is—working for NIWA—and I guess I ended up on terrestrial stuff.
And now, if you weren’t working at DOC, what would you want to be?
I’ve always had a hankering to be a helicopter pilot or failing that, a photographer for National Geographic.
What sustainability tip would you like to pass on?
Turn down the thermostat on the hot water cylinder by a couple of degrees—they are often set too high. I’ve done it a couple of times and my wife who loves her hot showers hasn’t squealed yet.
Which green behaviour would you like to adopt this year—at home? At work?
Get the compost working better and grow more veggies.
If you could be any New Zealand native species for a day, what would you be and why?
There are a whole lot of them that I really admire—the diminutive wee rock wren, the fearless falcon (I saw one trying to attack an Iroquois helicopter that came too close to its nest) the melodious kaka – the list is endless. However, imagine going back in time and being Harpagornis/Haast’s eagle. Now that would be something.
