Another Kiwi Killed by Dog

“Sprat” – Wild-hatched Kiwi

Unfortunately, when checking Sprat’s monthly location for July, the signal from his transmitter was a “mortality signal” – meaning either he was dead or he had dropped his transmitter. When located, all that was left of Sprat was a pile of bones and a few feathers. The bones showed evidence of a dog kill (broken ribs and a puncture wound to the skull). The data from the transmitter gave his date of death as around the 24 June 2010. We have been checking with locals at the Nook for any sightings of uncontrolled dogs around that (or any other) time. Sprat was a wild hatched kiwi who had become “Jackie’s” partner last season and we had put a transmitter on him to monitor nesting (the dad’s sit on the eggs). Unfortunately 50 years of potential breeding by Sprat has been lost.

Here’s the July update for monitored kiwi in the Whangarei Heads, as reported by Todd Hamilton, WHLF kiwi ranger:

Dallas is in the pines north of the Whangarei Heads School and is coming up on 2 years old so had his transmitter upgraded to a “Chick Timer” transmitter to check for any nesting.

Darwin is hanging around the wetlands by Lamb Road and is also sporting a new transmitter. He is in excellent condition and weighting 2425g.

Daniel – is settled in the bush on the north side of Kauri Mt Road .

Xmas is still hanging around the edge of the recently logged horse paddock at Mcleod Bay

Violet is still in the pampas by Bay View road.

Lambert is once again showing himself to be a good breeder and is nesting on the west side of Taurikura Ridgewith chicks due in early October..

Whitu – is also nesting on the face of Mt Aubry above the Reotahi carpark and if successful should produce a chick or chicks around the end of September.

Dog Killed Kiwi Chick
Unfortunately a kiwi chick was killed by a dog in the Bream Head reserve recently. Someone was either illegally walking their dog there or the dog had wandered there the previous night. The 900g chick was found on the walking track on the way to the gun emplacement by locals out for a Sunday morning walk. This chick was a wild hatched chick that was getting close to stoat proof size. DoC have taken saliva samples from the body to DNA test to help identify the dog.
Here’s the May update for monitored kiwi in the Whangarei Heads, as reported by Todd Hamilton, WHLF kiwi ranger:

– Dallas is in a paddock of pampas just west of the Whangarei Heads School

– Jackie and Sprat are hanging out together at the Nook – hopefully getting ready to nest.

– Darwin has moved back to his favourite haunt in a pampas patch at the end of Lamb Road.

– Sleepy – had to catch Sleepy twice this month, once to upgrade his transmitter to a chick timer and then again a week later because the mercury switch in the new transmitter was faulty giving a mortality signal (if the tx does not move for 24 hours it trips a mortality signal). He was 2200g in weight.

– Xmas is still hanging around the edge of the recently logged horse paddock at Mcleod Bay.

– Violet is in the pampas by Bay View road- she had her 6 monthly check and was 2560g in weight and her bill was 132.9mm (she was 2440g and 126.6mm six months ago so she is still growing at coming up to 3 years old).

– Lambert is still playing hard to get in the gorse at the top of Taurikura Ridge.

– King – haven’t managed to get a signal from King this month, this is not uncommon for him as he often tucks himself down on the flax covered coastal cliffs at Kauri Mt.
It is the kiwi breeding season at present so the birds are calling each other regularly in the evening so it is good time to listen for kiwi in your backyard.

May 5th, 2010

Here’s the April update for monitored kiwi in the Whangarei Heads, as reported by Todd Hamilton, WHLF kiwi ranger:

– Dallas is just west of the Whangarei Heads School

– Jackie has returned from her stint on the Parua Bay side of the Nook and is back with mate Sprat on the western end of the Nook

– Darwin is still in the wetland by Lamb Road looking for some soft ground and any potential mates.

– Sleepy has moved from the Kiteone Road side of Oxborrows’ farm to the Nook road side.

– Xmas is hanging around the edge of the recently logged horse paddock at Mcleod Bay.

– Violet has moved from the upper slopes of Mt Aubry down to the pampas by Bay View road

– Lambert is due his 6 monthly tx band check but is playing hard to get in the gorse at the top of Taurikura Ridge.

– King had his 6 monthly check – he was 1960g, his bill was 100.4 and he is in reasonable condition.

– With the bit of rain we have had the adult kiwi should be starting to feed up well for the imminent breeding season – the birds should be calling each other regularly now in the evening so it is good time to listen for kiwi in your backyard.

Here’s the March update for monitored kiwi in the Whangarei Heads, as reported by Todd Hamilton:

– All monitored kiwi alive

– Xmas: was nesting near where logging of WDC pines took place in McLeod Bay, but stopped nesting and moved away from logging area. On a side note, the logging crew have been very good- I have monitored birds regularly and kept them updated but geeze logging makes a lot of noise.

– Violet: has moved away from logging area near the Club and settled onto Mt Aubry

– JR: has also moved away from an area of earthworks

– According to our “chick timers” there are no other nesters – all timers are indicating high activity (10 hours)- ie: they are moving, not nesting!

– Performed biometrics update for Dallas and Sleepy

– Performed a transmitter change for Sleepy (finally)

Lambert – Dad of the year

March 30th, 2010

Lambert is one of the kiwi chicks that we have brought into the Whangarei Heads area from a high density kiwi population out at Purua (west of Whangarei).

Nick Edgar, CEO of NZ Landcare Trust, with Lambert

He was hatched by “George” the kiwi (it’s the dads that get to sit on the eggs for 80 days!) at McGraths’ farm at Purua in December 2006.  He got his name from George Lambert who was an old time farmer out there that protected the bush his dad “George” nests in.

We transferred Lambert to the Limestone island kiwi crèche in the Whangarei Harbour at a weight of 260g. 18 months later (July 2008) we re-caught him using a trained kiwi dog to find him, he had grown to 1760g and was ready to come back to the main land.

He was released at the Hunts’ farm on the eastern side of the Taurikura Ridge by a group of locals and special guests NZ Landcare Trust’s head office. We put a radio transmitter on his leg as one of a sample of 15 kiwi we track at the Heads to check on their movement, survival and breeding progress.

Lambert spent the next year wandering around the Taurikura Ridge. He must have found himself a local girlfriend in that time because in August 2009 Todd found him nesting in a hollow Mangeao tree above Mckenzie Bay.  Lambert successfully hatched both eggs from that nest and we named them “Marita” (after Marita Hunt who has been working on the possum and rat control project at Taurikura Ridge) and “Amber” (who was named by the NZ Landcare Trust head office in recognition of their support of the Landcare projects at the Heads.

To successfully hatch two chicks is pretty good going for a 2 and a 1/2 year old kiwi, as kiwi are the slowest growing bird in the world and don’t fully mature until around 5 years old.

As if that wasn’t enough, Lambert and his mate started another nest in November 2009.  We knew this because after his last nest Todd had changed Lambert’s transmitter for a ‘smart’ “chick timer” transmitter that measures the movement of the kiwi using a mercury switch and indicates when the kiwi settles down to incubate an egg (pretty clever  technology!)

This nest was in a pampas bush in a pine plantation and in January 2010 Lambert successfully hatched another chick, which we named Jeremy, after the computer geek that developed this web site.

3 chicks in one season (and its not over yet) for a young kiwi male makes him our “Dad of the Year”.

About Chick Timers

March 11th, 2010

Chick timers are a “smart” kiwi radio transmitter developed by a couple of clever engineers in Hawkes Bay. They were sick of doing heaps of night field work on their local kiwi recovery project checking kiwi nests to see if chicks had hatched.

These guys (John and Al of Wildtech) have taken a standard kiwi chick tx (“tx” is short hand for transmitter) with a mercury switch inside it and added some software.

The mercury switch detects movement and the software basically counts how often the kiwi moves his leg.  High counts mean lots of movement. The software then interprets the trends in movement and sends out a coded signal in a data stream that we can monitor with our standard kiwi radio monitoring gear as series of beeps.  We put these tx’s on the males because it is the dads that incubate the eggs after mum has made a huge effort to lay them.

When the dads are nesting their activity is usually around the 3 to 4 hour mark. This is the time it takes the dad to sneak off the nest for a quick feed each night.  He usually nests for 80 days – the longest of any bird species.

This chart is the datastream for Whitu at Reotahi at 10.15am on 23 March 2010.  You can click on the chart to see the data, which tells us that there were 30 beeps per minute – and that’s good, because 30 is the signal for “alive but not nesting”.  It also tells us that it was 35 days since Whitu was last nesting, that he got up15 hours ago at 7.15pm, and was active for about 10 hours.  Two nights ago he was active for 9.5 hours, and he averaged about 9.75 hours of activity for the past four nights!

These chick timers have been great for monitoring our kiwi. We use them on the dads in Purua that are part of the BNZ Save The Kiwi Operation Nest Egg programme to tell us when a chick has hatched and is ready to be moved to the Limestone Island kiwi crèche. They save heaps of field work time that was previously needed to visually check kiwi to see if they were nesting.  These transmitters also mean the kiwi are far less likely to be disturbed by whoever is monitoring them because they can do it from a distance.

WHLF launches Backyard Kiwi

March 2nd, 2010

Look out for our road signs in Whangarei Heads.

Whangarei Heads Landcare Forum are delighted to introduce Backyard Kiwi, a community conservation and awareness project.

Whangarei Heads is a unique environment and over the past 10 years with improved predator control the kiwi population has grown from just 80 in 2000 to more than 300 in 2010.

“Backyard kiwi” is the initiative of the Whangarei Heads Landcare Forum, a local Landcare group working to enhance the recovery of kiwi populations at the Whangarei Heads.

Willy Oxborrow putting up the new "backyard kiwi" sign

You will see signs at the Whangarei Heads turn off and around the Nook and Kauri Mountain reminding us that we are some of the very few in NZ who can see/hear kiwi without going to the zoo!

And watch out–that may be a kiwi on the road at night, not a possum!

Sketching the Backyard Kiwi

February 2nd, 2010

An integral part of the Backyard Kiwi project was creating an illustrated kiwi character which would strike a chord with people in the area. They wanted the Backyard Kiwi to pop up on billboards, bumper stickers, postcards — anywhere he could!

Heather Hunt, an Urquharts Bay-based illustrator and graphic designer, was chosen to give the project its mascot. To create lifelike kiwi which would capture the feeling of the project, Heather worked closely with Todd Hamilton, going on some enthralling kiwi hunts to observe kiwi in their natural habitat.

“Todd was my best critic in developing an illustrated kiwi character. I wanted it to be a kiwi that people could relate to and Todd wanted it to be true to kiwi. I’ve learnt heaps about how kiwi live and move, and over several months Todd and I have come up with an unique illustrated representation of a kiwi. It combines humour and integrity with Todd’s exacting and intimate knowledge about ‘real kiwi’.”

Heather managed the art direction and graphic design for the backyard kiwi project and is currently working with an author to illustrate a children’s picture book.
