Nesting pied shags on Kapiti Coast New Zealand


Welcome to the Midnight Collective Broadsheet 148
Actively supporting NZ’s endangered wetland birds

Mum settles down...
Today a quick note, plus video on a pied shag colony 30 km north of here established in the macrocarpa at Waikawa Beach. This beach is famous as the bolt hole of provocative early Labour Minister of Public Works ‘Red’ Bob Semple, so first things first –

For those not currently up with the state of political play in New Zealand and who have been patiently ‘watching this space’  as advised, we do have a new Labour-led coalition Government which includes the Greens.
 96 years later and here she goes - Jacinda Ardern PM
It is very early days but a first big test is on the horizon with the Climate Change conference about to get underway in Bonn Germany. PM Jacinda Ardern and James Shaw – leader of the Greens have both attended in the past and Fiji is providing leadership, so we are expecting major support for ‘at risk’ Pacific nations to emerge from this new Government, which early declared its serious concern about the Planet's slide into global warming.    Now back to the shags…

Growing chick with parent regurgitating
This pied shag colony along the Waikawa stream is only three or four years old, but growing steadily and we were lucky to be able to catch some film of the nests of  parents with their young. We had to film from a distance, then through tangled branches so apologise in advance for the quality – but here are youngsters being fed and parents swapping over nest sitting duties. 

There are at least two chicks in each nest, one of which is rather larger than the others and busy copping the lions share of the regurgitated food.
Pied shags, our largest shag, are coastal birds that feed in the sea and estuary. They had a bounty on their head in the 1940’s when their numbers plummeted. There is still surprisingly little information about how they are faring nationwide with population estimates varying between 1000 and 5000, though they are thought to be in decline. They appear stable on this coast however and our marine reserve must be a big help in growing this local population.  The major threat is from continued shooting, the deliberate destruction of nesting sites and net fishing.  The experience of two locals shows why.

They were visiting the colony and found a bird enmeshed in a net set right below it. They jumped into the creek to free the bird but found it so thoroughly entangled they had to send home for a knife in order to cut it free. The bird fortunately, was no worse for her ordeal but not at all thankful for its rescuers. It bit the finger of one, causing blood to flow and when released dived down and bit his toe. First aid had to be rendered to the rescuers and the safest way to hold it (to protect themselves) was by the scruff of the neck. On this evidence the future of this bird looks assured!
  

Midnight Collective Conservation Order of the Month goes to those two who cut up the net then advised the authorities. 

Track we were listening to while posting this was Fats Domino's Blueberry Hill, 89 years old when he passed away last Thursday (our time). If you are a Treme fan you would have seen him as a highlight of  Series 3, at his house, post-Katrina, playing the piano, looking all sorts of worn, but still with those magic New Orleans fingers playing over the keys.

Love's sweet melody
But all of those vows you made
Were never to be

Pollution at Kapiti wetland - the continuing story


Welcome to the Midnight Collective Broadsheet 147
Actively supporting NZ’s endangered wetland birds


Still mucky after all these weeks

We have taken a while to follow this up because we have been away on a jaunt. However we pursued this pollution story with the Regional and District Councils and here are the results; Regional Council first.
The investigative officer sent our photographs to their science lab, who came back to them (a week later) with a definitive judgement (from the photographs), that this was a natural phenomena, a reaction of bacteria to ferrous iron, that sometimes occurs in recently disturbed waterways. It was therefore not a pollutant issue. We had also consulted the District Council who filed a similar story, having obviously been in contact with them.
Naturally stagnant? - Is this now a permanent feature of our wetland? 
There are issues around this that need to be brought out into the open. No-one from either of these organisations carried out a site inspection, so no water samples were taken to confirm the judgement. The Regional Council is based in Wellington  an hour away. This travel time and expense seems now to be factored into their decision making. It also confirms that much of their work day is spent in the office talking to their laptops. This has not gone unnoticed by people we have talked to on-site. ‘They’re all just academics,’ was one caustic response. None of this decision-making took into account the fact that the pollution appeared to start around the dumped rubbish and oil cans, then flush out into the wetland. The District Council said they would send someone down to clean up this mess. A month later it still hasn’t happened.
Now you see it.
Now you see it (Month later)
We have had above average rainfall over the last few weeks which should have flushed the area but this ‘non-pollution’ is now spreading, leaving wider areas stagnant.


The NZTA is still working in the area, reinforcing the drainage banks, so the area isn’t draining the way it was designed to; though, needless to say, none of this shemozzle is filtering into the news media.

And this work appears very ad hoc, drying up the wetland at a time when it is usually at its peak. This is a worry for nesting birds like pukeko and pied stilt which rely on the water to safeguard their nests and their youngsters. Yet there seem very few nesting birds down here. We’ve spotted a couple of ducklings and two pukeko chicks at a time when there are usually three or four broods of both.

No pied stilt so far and no paradise duck broods. Though a couple of spurwinged plover pairs are skulking around (these self-introduced  predators feed upon native eggs and chicks).
Coastal wetland areas (pakihi) are notoriously difficult to define however, for they change from season to season. And it is still early days in the life of this one so let's finish on a positive  note. Every year NZ holds a kereru count (these birds are crucial for spreading large forest tree seeds). There are populations in the Tararua forests around here but we have never seen them down on the coast, so imagine our delight when for the first time one gate crashed our kowhai.
Here’s the video

But what is going on? Tui numbers have been up again this year and it’s possible that the tuis are dragging curious kereru in their wake.

Tui - ditto repeato
Kereru also feed on kowhai, but on leaves not flowers. Another native bird that has been spotted locally though we haven’t seen her yet, is our endangered native falcon – karearea. And she may also be following the tuis. One was apparently spotted chasing a tui away from a feed in a back garden; though we need photographs to confirm this.


Track we were listening to while posting this - well it had to be, Halloween drawing ever closer on our luxurious spring parade

I was working in the lab late one night
When my eyes beheld an eerie sight
For my monster from his slab began to rise
And suddenly to my surprise

He did the mash
He did the monster mash
The monster mash
It was a graveyard smash
He did the mash
It caught on in a flash
He did the mash
He did the monster mash
