The first kākāpō eggs in three years have been discovered by rangers on Codfish Island/Whenua Hou. The two nests that have been found so far belong to Lisa, an experienced kākāpō mum, and Tumeke who has bred before but had infertile eggs.

Both Tumeke and Lisa have laid two eggs each – but it will be another week before it’s known whether their eggs are fertile.

Today’s photo of the week is of Tumeke being viewed on her nest through a video monitor.

Kākāpō breeding and nesting on Whenua Hou is triggered by the amount of rimu fruit available on the island, as it is the food that the mother kākāpō relies on to feed her chicks. There has been no breeding during the past two summers because of poor rimu crops.

The Kākāpō Recovery team is preparing for the possibility there could be up to 15 kākāpō nests this season.

The takahē population on Mana Island have had a few new pairings formed over recent months, as a result of the sort of behaviour that could only be likened to an episode of “Days of our Lives” or “The Young and the Restless”.

While it is not always a good idea to anthropomorphise a wild animals behaviour, the antics of one of our recent immigrants does seem to warrant it.

McCaw (named when she hatched soon after the All Blacks won the 2011 Rugby World Cup) came to Mana Island from Maud Island in the Marlborough Sounds for an “arranged marriage” with one of our young lads.

McCaw spent three weeks in a large enclosure with her new suitor, Nohorua. They appeared to be getting along, but as it turned out she had other plans. The male from another pair that lived beside the enclosure had caught her eye. Within a couple of days of release McCaw left Nohorua, and used her youthful energy and good looks to split up the long established pairing of Kat and Santi.

But like all good day time television dramas these heart breaking acts had a happy outcome for some; McCaw and Santi have just started nesting. Kat – after licking her wounds and shaking her tail feathers has landed herself a younger man in Hori. But what of the jilted Nohorua you ask? His quest to find the perfect match continues.

Our takahē are well into another breeding season, with nine pairs nesting. The first nests of the season have started to hatch so hopefully we get a reasonable run of weather to help the chicks establish.

We had planned to do another egg transfer to Southland this year, but the birds had other plans. Our birds were a bit tardy in getting going while the southern “foster” pairs started earlier. The requirement for them to start around the same time was lost on the takahē, but at least they’re nesting!

The West Coast Blue Penguin Trust have been busy building nesting boxes for the local population of little blue penguins/kororā.

A nesting box ready for action!

Timber and materials were kindly donated by the local Mitre 10 in Westport during Conservation Week and the Buller conservation volunteers group spent a day helping to build the new nesting boxes.

These volunteers are a group set up by DOC. They meet at DOC’s Northern West Coast District Office every fortnight and go out with a DOC ranger to do a variety of work for the day—planting, helping community groups, track maintenance, historic maintenance and an array of other jobs.

The volunteers helped to build ten nesting boxes. The hope is that baby penguins hatch in the boxes and are given a measure of protection against predators.

The boxes were placed out in a penguin colony at Charleston on the West Coast to create penguin homes for when the little blue penguins are nesting. The West Coast Blue Penguin Trust monitors the boxes throughout the year.

It was a great day had by all, bringing together a wonderful partnership between the community, business, volunteers and DOC staff.

Whilst many folk are doing their best to be seen on our beaches this summer, some of our more secretive residents are struggling with the crowds.

I’m talking about the NZ dotterel (tuturiwhatu) which nest in sand scrapes on many of our North Island beaches.

These birds and their nests are well camouflaged and often invisible to the untrained eye, leaving them vulnerable to disturbance by unwary beachgoers, their dogs and vehicles.

Today I’ve had a report from a member of the public about people walking through the fenced off nesting site at Matakana to relieve themselves and to sit in the sun.

It’s true that sometimes the birds choose to nest in places that are inconvenient to beach users, but in the scheme of things, I’d suggest that the inconvenience of having to walk an extra 100m is a small price to pay for the survival of this species which numbers just 1700 individuals in NZ (and the world!)

and the results can be devastating – this chick was crushed by an unwary motorist

When dotterel adults are disturbed off the nest while incubating, the eggs are at risk of overheating. Young chicks, when disturbed, can die from exhaustion as they cannot eat in time, or get to their feeding grounds at the water’s edge.

Here in Tauranga we have major dotterel nesting sites on Matakana Island and Maketu spit that are protected through the efforts of Ranger Witana and the Port of Tauranga at Matakana and community volunteers at Maketu whom control predators, monitor breeding success and fence off the nesting areas in an effort to protect them from being disturbed.

Birds bred at Matakana last year have recently been seen at beaches around the Coromandel and East Cape.

So as you enjoy the beach this summer, please spare a thought for the shy locals (even if you can’t see them) and give them a little space.
