Caspian Terns at School

Sarah Harrison told us that the Caspian Terns were nesting near our school so we went and had a look , we did some sketching and did some research.

Did you know?

The Maori  name for the Caspian Tern is Taranui.  The scientific name is Hydroprogne caspia.

The Caspian Tern is one of the largest terns and they nest on a rocky point outside our school in Mulberry Grove.

Adults have black legs and a black cap to below the eye during the breeding season. But the black cap becomes speckled or spotty when they are not breeding.

We found out the chicks and eggs are in danger from cats and dogs because of where they nest, sometimes the tide and the waves might wash the eggs away.

Caspian terns can breed in groups or just as a pair with other terns or gulls.

The nest is a shallow scrape in sand or stony ground and may have some grass, feathers, sticks or other material. The two parents share sitting on the eggs . They lay  1–3 dark speckled light grey or olive-brown eggs and take about 3 weeks to a month to hatch.

Caspian terns are vulnerable because of people, their dogs, and off-road vehicles. Black-backed gulls and red-billed gulls may attack eggs and chicks if people disturb them.

Eggs are laid from late September through to late December. Chicks are fed whole regurgitated fish by both parents.

Lodge Opening

Visitors off the boat

On Saturday 23rd March 2019 the new lodge on Motu Kaikoura was opened.  150 people attended alongside the noise of many kakas.

Motu Kaikoura, within Port FitzRoy, is a scenic, public reserve to support natural regeneration of the vegetation free of invasive plants and animals. Since the eradication of deer, regeneration is very obvious, and bird life is increasing. Rat eradication is an ongoing struggle.

Current volunteer trustees are: Rod & Rosalie Miller, Geoff Davidson, Mike Lee, Mel Galbraith, Harry Doig, Sue Daly, Gemma Parkin and Kim Grove. We meet monthly to discuss issues ranging from eradication of rodents and weeds, maintenance of roads, tracks, machinery and always finances. A source of income now are the cabins upgraded by Warkworth Rotary volunteers.

Houhere  |  Hoheria populnea

It is the  Lacebark that you are most likely to see on Great Barrier and is in flower now until May.  An erect, much branched tree that grows up to 10m or so. The common name comes from the pattern of the stringy interlaced bark.  The somewhat leathery leaves have quiet marked serrated margins up to 14 cm long by 6 cm wide.

This variety can be semi deciduous, becoming nearly bare in the winter. That is if your local Keruru has not already near denuded it.

The flowers are about 2.5 cm in diameter and pure white with many stamens. Growing in clusters or singly in great profusion. They have a slight scent.

The fruit are odd looking and winged, with fine seed cases each with a single seed arranged as wings around a central axis. They germinate well as anyone who has Houhere in their garden will tell you.

A tree that is well worth it in the garden.

Trap Library

Auckland Council Environmental Services has made a significant grant for traps and trap boxes for residents and landowners on Aotea. If you want free gear all you need is a commitment to all year round trapping. When you apply, you supply your address and sign up with TrapNZ to record your monthly catches.  If after 6 months you have not used the gear or recorded your figures then you need to return all gear.

The first depots are being set up at Mulberry Grove School,  Motairehe Marae and Glenfern. Additionally, the Great Barrier Island Environmental Trust have them available.  Traps and boxes are also available at cost to those who do not wish to be part of the island -wide register.

This is a great opportunity for community groups to set up projects with the help of the Ecovision facilitator and Auckland Council. Okiwi are leading the way and of course the existing sanctuaries are always ready to help new set-ups.

Ecovision Update

The Ecovision initiative is a project of the Great Barrier Local Board to facilitate ecological restoration projects to develop and collaborate towards a shared ecological vision. Project representatives meet every month. The next Ecovision Open Day invites everybody interested in ecological restoration to visit Glenfern at 2pm on Saturday the 11th May. The new ‘Oruawharo Medlands Ecovision’ group,  with the advice of Professor John Ogden, will soon be starting an ecological study of the surrounding areas to identify and monitor issues deserving more attention. If you are a Medlands resident and would like to join this group, or be part of one in your area, contact Rendt on 029 770 7123, via Facebook: Great Barrier Ecovision or learn more at http://greatbarrierecovision.on-the-inter.net/

Dumping of Dredgings

On the 5th of February this year, Coastal Resources Ltd was issued a 35 year permit to dispose of 250,000 cubic meters per year of dredge waste from Auckland and Waikato, 25 km off the coast of Aotea (Great Barrier Island).

Kelly Klink, of iwi Ngāti Rehua-Ngātiwai ki Aotea, and the Society for the Protection of Aotea Community & Ecology, have lodged appeals against the resource consent in the High Court. Both appeals have been accepted by the High Court and are awaiting a court date.

Ngati Rehua Ngatiwai ki Aotea have a significant and an undeniable interest within the area - holding mana whenua and mana moana. Kelly states that “the proposed activity will have an irreversible impact on our moana” and “the harm will be irreparable to the wairua and mauri of Moana nui o Toi, adversely affecting the marine environment upon which our iwi have relied on mai rano”.

What can you do to help?

Okupu Beach Birds

Okupu is happy to let you all know that we have one NZ Dotterel that has grown to maturity.

In early November a nest was found with 2 eggs, they hatched at the beginning of December. Unfortunately within a week one chick had disappeared but the second one never looked back. Very protective parents.

A second pair of NZ Dotterels also attempted a nesting  but were washed out in the Christmas high tides and storm.

We also had a pair of Variable Oystercatchers attempt nesting. First time in about 5 years. One egg. The first nesting was at the same time as the NZ Dotterels and within a few meters of  the dotterels nests. Unfortunately that nest failed at about the time the dotterels hatched. End of December they re-nested at the same site with one egg again. This egg failed as well but the parent refused to give up and sat on the nest for nearly 2 months—it takes about 32 days for an Oyster Catcher egg to hatch.

The fact that the birds nest at the same time, that people like to use beaches, and that they have more than enough natural predators to put up with, explains why it is no wonder they have a hard time. The birds  will get off the nest when you come onto the beach and stay off if you linger too close to the roped off area. When the parent is off the eggs, they can cook in the hot sun or get too cold in a strong wind—the egg can fail due to these temperature changes.

All credit to those people who took time to look at the signs and kept their distance from the roped off area, and those dog owners who kept to the northern end of the beach or went down at low tide.
