7.1.1c Kaka Recovery Programme (DOC) - Project Details:
The kaka - our native parrot
Its home in the Whirinaki Forest
Setting the net
careful handling of a precious bird
A little food makes a new friend
In safe friendly hands - contented
measuring that sticky beak
Fitting it's nametag
identified for research
fitting a radio tracking backpack
sealing the knots
later Claude prepares for a climb
Next stop - the nesting hole
Be careful Claude, its a long way down
Oberving by closed circuit TV
Aah yes that chick is safe
It's good to be back with you earthlings
There is mum going back to the nest
A lot of explaining is to be done
WHIRINAKI KAKA INORMATION.
SPECIES: Kaka (nestor meridionalis septentrionalis.)
Weights.
(Averages ) Females 430 gins Males 480 gins.
Colour.
Greyish crown, olive/brown back, reddish brown underbelly, splashes of orange red under the wings yellow brown tinges beneath the eyes.
Habitat.
Beech forest, mixed podocarp I hardwood, exotic plantations.
Food / Feeding.
Kaka feed at all levels of the forest strata from high in the emergent to ground level on invertebrates, fruits, seeds, sap and nectar.
Home ranges.
20 hectares, winter & summer home ranges, 80 hectares with huge variables.
Sexing.
Beak measurements taken with callipers 47mm and less indicates female.
Anything above 47mm is a male. Cloachre swelling in females is noticed in the breeding season
Breeding season.
A good breeding season will start around October with pairing and will go through to June when the late chicks fledge.
Phenology & synchronism.
The cycles, periodicity, synchronicity of flowering and fruiting food source
trees.
Insufficient food source means insufficient weight gains = no breeding.
Sex ratios.
About 4 :1 in favour of males.
Breeding.
Some pre-cops activity “head bobbing” initiated by the male.
Cops lasting up to 30 minutes. Some “beaking” activity.
Nest hunting.
The male kaka finds a possible nest site. The female accepts the nest or rejects it.
Nest sites.
Cavity nesters . Host trees include rimu, totara, matai, beech. A typical nest, vertically cylindrical shaped hollow with a solid base, plenty of dry rot matter to the upper walls. One or two entrances. (simplistic view.)
Eggs:
Average clutch 3. some lay more then this and some less. Egg laying usually occurs over a week. Colour is white 40mm x 30mm. (variable) Nests can fail through eggs being infertile.
Incubation.
Up to 25 days.
Brooding / post natal.
55—60 days spent in the nest growing up. The male kaka brings food into the vicinity of the nest then calls the female out to be fed. She in turn regurgitates some of the food and feeds the chicks. As they grow they are increasingly left on their own so that the female can also get out and about to forage for food. Down stage — pin feathers — feathered.
Fledglings.
Chicks are called and coerced out of the nest chamber when they are fully feathered. Their wing muscles are not fully developed. They are often heavier in weight then their parents. Suppression of food is often used by the female to get the last remaining chicks to take flight. If they don’t land in a handy tree nearby they nearly always end up on the ground. They can remain on the ground for several days. They try and remain motionless unless provoked by hunger when they begin wing flapping and “begging”. When they gain some semblance of flight and strength they make their way higher into the canopy. They eventually come under their parents tutelage for a few weeks before eventually dispersing.
Breeding age.
Females = 3years.Compared to captive bred birds (Mount Bruce) 1 year.
Predators.
Highly vulnerable to predation whilst nesting.
Rats (eggs) Musteids (all stages ) Possums (egg, chick, juveniles ) Falcons (
juveniles, sub-adults.)
