Spring has arrived this past week in Dunedin with the return of Taiaroa Head’s northern royal albatross/toroa. Today’s photo of the week is of an albatross coming in to land for the upcoming breeding season.Continue Reading...

New Zealand’s magnificent shorebirds are masters of their elements but they only reach this supreme state of being after rigorous training of mind and body.
To a casual observer, the birds are just mooching around, or foraging for food, but look closer. You might be surprised to see what they are really up to.
I dropped in on a couple of Wellington’s shorebird chapters: the beach chapter at Petone, and the city branch at Wellington Harbour, to watch their training sessions.
A pair of oystercatchers were just finishing their afternoon tea at the beach to fortify themselves for their self-improvement class. The first one led the way, closely followed by an inquisitive red-billed gull.
The tide was in and pounding against the end of a concrete pier.
The pair of oystercatchers took their positions at the end of the pier where the raging sea would drench them. They showed no fear but just stared down the approaching waves.
The gulls arrived shortly afterwards but they were the new entrants to the class, taking a back row – watching and learning from the masters.
With the skills learned from the beach, the gulls tried to apply them, in the comparative privacy of Wellington Harbour. Their test was to hone their flight skills on a spectacularly windy winter’s day. Their test area was the outfall from the wetland next to Te Papa.
As they arrived, their first task was to stand their ground in the face of the wind that was blowing the falling water back the way it came.
Following the example shown by the oystercatchers, the lead gull stepped to the edge to show no fear while being pelted by the spray and then to execute a flawless take-off.
Clearly a bit more practice was needed. He was nearly wiped out by a cross wind. It must have dented his confidence as I saw him later retaking his beginner’s take-off class. By that time, I had to get back to work, so I never witnessed the landing.
More than a third of the 80 or so species of sea and shore birds that breed in New Zealand are found nowhere else on Earth, including the variable oystercatcher.
Both variable the oystercatcher and red-billed gull are native to New Zealand and are often found around our coast.
Do you have a ‘chapter’ of these shorebirds near you?
Titi, or sooty shearwaters, have one of the longest migrations of any bird on the planet.
Department of Conservation sea bird scientist, Graeme Taylor, is on Rangatira Island, in the Chatham Islands, to find out where they go.
His team employ a novel approach to try to retrieve 16 geolocators in 10 days.
Have a watch…
Rangatira Island, is one of New Zealand’s premier sea bird islands. It is free of all introduced pests and it is riddled with sea bird burrows.

Last month I shared a photo of one of our newest, cutest, and fluffiest additions here on the West Coast — a one month old Westland black petrel chick in its burrow just south of Punakaiki.
One month later and look what the fluffy petrel chick has turned into!
Like all children, this one grew up very fast, and has turned into an almost adult looking Westland black petrel. He has kept his handsome smile though, as well as some fluff on his belly.
His parents fed him well but, when he got too chubby to fit through the tunnel to get out of the burrow, they left him to get back into fighting fit shape for his next big adventure — flying practice!
Flying practice involves jumping off a cliff, launching into the air and, most of the time, a not so graceful crash landing. Good luck petrel, we’ve got our fingers crossed for you!

The chick’s parents still come in for feeding time in the evenings by doing an “elegant” crash landing in the canopy. They then drop to the ground, looking slightly disorientated for a few minutes, before regaining composure and waddling off to their burrow to have a noisy and somewhat reproachful chat with their partner. A bit like: “Did you actually forget to bring the Hoki? Do I now have to fly ALL THE WAY back to Hokitika to get one!”
In the morning mum and/or dad petrel will have to jump off the cliff to get airborne as their legs are too short to get them going on even ground. And off to another day at sea. Isn’t it amazing what these guys take on to raise their chick?
But let’s be honest – who wouldn’t, looking at a fluffy thing like that?
Today’s post was provided by the Southern Seabird Solutions Trust. The trust is a partnership between the commercial fishing industry, WWF and the government.
At this time of year there is plenty of night time activity at the top of Mt Hobson/Hirakimata on Great Barrier Island. Black petrel chicks, with new glossy adult feathers, are coming out of their nest burrows and furiously flapping their wings. When they feel strong they waddle to a prominent rock and launch themselves, flying off towards South America where they stay for a few years before returning to find a mate and nest.
Black petrels used to breed on high points throughout the North Island and top of the South Island, often flying far inland to nest. They played an important role in the health of the forest, bringing rich nutrients into the ecosystem from the sea. Their droppings, eggshells, and dead chicks were deposited in the forest and they aerated the soil with their digging, acting like little composters.
This annual foray inland went on for millions of years. After the arrival of people the mainland colonies slowly disappeared as habitat destruction and predation by rats, cats, stoats, and pigs got the better of them. There are now about 15,000 black petrels left in the world, and of these only around 2,000 breeding pairs.
Whitianga and Leigh longline fishermen Adam Clow, Wayne Dreadon, Gavin Perry, Clayton White, and Mark Dellow, along with Leigh Fisheries employee Angela Cole, and boat builder Mitch Pascoe, recently joined Biz Bell, Seabird Researcher, on top of Great Barrier Island to help band black petrels before they flew off.
“Five minutes after meeting Biz I was up to my armpit in a black petrel burrow, carefully pulling a bird out then holding it while she banded it,” Gavin says.
“They’re smart birds and have an extraordinary homing sense. On land the path they use is like a bird highway at night, as black petrels from nearby burrows waddle to the rock they take off from. After the chicks have left for South America the parent birds fly there too and, the following spring, they fly back to their burrows and meet the same old partner.”
It was also an amazing day for Adam: “The biggest thing for me was the realisation of how special and smart these birds are and how rare they are. I learned that they have a low survival rate and that fishermen here and in South America play a part in their decline.”
Gavin says that no fishermen like catching birds and he and others in his fleet follow the Leigh Commercial Fishermen’s Code of Practice, developed by Leigh fishermen over 20 years ago.
Wayne, Adam and Gavin agree the dangerous time is when they’re setting gear before dawn and birds want to dive on the baited hooks. They use tori lines to keep the birds out of the danger zone and weights to sink the baited hooks fast so the birds won’t dive on them. They make sure the deck lights point in inwards to minimise the visual presence of the boat at sea. And they hold scraps onboard when there are hooks in the water – tipping a bucket of fish scraps overboard is like a dinner gong for seabirds.
“This experience hammered in the vulnerability of these birds and their importance as a species. It gave me a totally new respect for them. It would be great if all fishermen did this trip to the colony at least once,” Gavin says.
“Our fleet has been aware of the risk to seabirds for many years and we will continue to do our bit to protect them, and to help others. A few years back a Leigh fisherman went to Peru to talk to fishermen over there about ways to avoid catching seabirds.”
Wayne agrees that helping band black petrels was a primo experience. “Watching them waddle to their take-off rock and fly off, into the night, was a primeval experience. These birds have been doing this, from this place, for thousands of years. All fishermen are obligated to work as a team to look after black petrels so they will continue to have a place, here, for thousands of years to come.”
