Coromandel Striped Gecko |
The most exciting news
since the start of summer has been the discovery of three geckos on the estate.
Two of these, discovered and photographed by Sara Smerdon, were Coromandel
Striped Gecko – possibly the rarest Gecko in the world. The species was discovered
on the Coromandel at the end of the 1990s and only a handful has been seen
since. We are awaiting further information from scientists and DoC experts but
most or all previous records have been from the 309 road north to Moehau.
Sara’s records may extend the known range of the species. This is a beautiful
and quite large gecko. Both the individuals Sara photographed had previously
dropped, and were regrowing, their tails. Reviewing photographs on the internet
I see that this is also true of other individuals. It will be interesting to
know if this is the case with all gecko species or if these geckos are
particularly vulnerable to predation.

The other Gecko was
found and photographed by Kevin and Cynthia and looks like a forest gecko.
These photographs have also been sent away for verification.
It is important to
know that it is illegal to handle or keep in captivity any of the native
lizards. All are especially vulnerable to predation by cats and rats. These
gecko records further illustrate the incredible diversity of rare species that
we live alongside at Mahakirau.
Around the house there
have been a number of Copper and Blue Butterflies as well as visits from the
occasional Red Admiral and Painted Lady. The lack of cicadas is noticeable and
we have seen fewer puriri moths than usual. Apparently cicada numbers are low
across the country. This is a consequence of what was going on five years ago when
they would have started their life cycles.
In the hot dry January
we have just enjoyed, the bush has been relatively quiet as far as birds are
concerned. We have several families of silvereye, fantail, tomtit and bellbird
in the bush around us and kingfisher have been noisy at times. A lone kaka flew
over the house in mid January – but they seem to spend time at more elevated parts of the estate, only
occasionally visiting us at 300masl. Two Black backed gulls flew over the estate in December – a
surprisingly rare occurrence. Californian Quail appear to have had a bumper
breeding season with several parties of more than twenty chicks. The number of
well grown young suggests that stoat and weasel numbers must be low – a tribute
to the pest control team.
Shining Cuckoo are
still calling occasionally. At the end of December we had an interesting
experience when about ten cuckoos spent an hour or more in the mature Tawa tree
immediately beside the house - calling incessantly. They were very agitated
displaying to each other with outstretched and quivering wings and tail. Every
so often there would be wild chases through the tree canopy and at other times
they could be seen feeding on caterpillars. After they flew from the tree I
heard them continuing to call about 100 meters away. The next day a smaller
number of birds returned to the Tawa and began calling again. According to the
Handbook of Australian, New Zealand and Antarctic Birds these communal displays
may involve up to a dozen birds although I have not seen more than six birds
together before.
Forest Gecko |
Finally, it was a good
spring and summer for many of the flowering forest trees. Hinau and Rata had
particularly impressive seasons and now white rata are flowering well.
Another great article Allan. It seems the Coromandel striped gecko may be more numerous than experts think, in part due to Sara’s efforts! We probably don’t know enough about their habitat preferences, hence where to search in order to get an accurate picture of range and numbers. I also note from an early paper on Stephen’s Island striped geckos that over 46% (from a large sample size) of those captured had lost their tails at some point – noticeably greater than other native lizards. It would be wonderful to know which species of lizard inhabit the estate and in what numbers. On another note I’m pleased that the butterfly fauna gets a mention as their conservation, together with other invertebrates, seems to be a low priority compared to birds and other mega fauna. We really need to consider the entire ecosystem from the bottom up if it’s to be self-sustaining. Please keep posting as I’m looking forward to your next instalment.
ReplyDeleteBeautifully written Allan. Oh what a privilege it is to live in this miraculous forest, where we can keep discovering something new and expand our knowledge! It is an inspiring and healthy way to live.
