It has been a
frustrating spring. Just when the weather appears to be improving there is
another wintery blast from the far south. The few still warm days have been
glorious but they do seem to have been few and far between.
This year we have had
high pest numbers to contend with. Rat numbers were exceptionally high in our
pre-control monitoring. This followed a major seed drop earlier in the year. In
the past month or so several stoats, a weasel and two ferrets have been
trapped. More rabbits have appeared on the un-forested parts of the estate and
these may have attracted the ferrets. Our pest control contractor has been
working on the possums and rats and I have recently seen young bellbird and
tui, so some birds have successfully raised a first brood.
This has been an exceptional year for seeds and flowering in the forest. At present, Quintinia is looking impressive and white rata are in full flower.

Several people have
commented how the bush seems to be less dense than it was. From our near ground
human perspective the adjacent forest does seem to have opened up but I think
that this is simply the forest moving towards maturity.

So far this year I
have completed sixty-four 5 minute bird counts within the estate. This is the
only way of providing a direct comparison of the bird numbers year on year.
Numbers of all the native species appear to be consistent with previous years.
This year I first heard Shining Cuckoo on the estate on the 18th
September – nine days earlier than last year. As with last year a kiwi called
near the house in late September. It is difficult to know whether this is a
consequence of kiwis moving within the estate or simply reflects the warmer
evenings and the fact that we spend more time on the decks. Sara and Rogier
recorded Kaka on the upper estate most evenings for a period in spring.
The most exciting and
unusual bird record on the estate was seen and photographed by Jude
Hooson. In misty conditions a
Diving Petrel was attracted to the house lights at night. Jude was able to
photograph it as it fluttered around on the deck. Unfortunately the mobile
phone photograph at night through the ranch slider is not clear enough to
reproduce here, but is just adequate for identification purposes! The Common
Diving Petrel (kuaka) is a small seabird (20cm) which breeds off the NZ east coast
including the Mercury Islands and spends most of its time in adjacent waters. It
is the most aquatic of all petrels. It flies with a whirring flight close to
the surface of the sea. Strangely, Jude said it appeared to be attracted to the
moths fluttering against the window. This was probably a response to their
movement not as a source of food. Diving Petrels feed mostly on small krill and
copepods, swimming underwater using their wings and legs for propulsion. A
fascinating record for the estate! It just shows that almost anything
can turn up. It also reinforces the importance of taking photographs. Had Jude
told me she had watched a Diving Petrel chasing moths on her deck 475metres
above sea level I would have suggested she should be certified! With
photographic evidence, Jude has made a most extraordinary ornithological record.
