Our most perfect winter and early spring weather comes when the
wind blows directly off the snow-clad Ruahine Range, the nights are frosty,
the days are still, the lake a sheet of glass, the blue sky cloudless.
During weather such as this in early August, everywhere on the run may
be heard the long, tremulous trill of the Warbler, rather like a cricket's
cry than a bird's.
Presently, from some manuka thicket, a sombre plumaged little bird will
emerge, light on some topmost twig, and pour forth to three-quarters of
the globe - for in his ecstasy her nearly sings a circle - this faint
sweet trill that heralds fuller spring.
Although a plentiful species on the run, even in winter the warbler's
presence about the homestead is infrequent. During spring he is even more
rarely seen; he has then, like all the native species, retired to breed
in deeper solitude than a New Zealand homestead can afford, but though
gone, he has not gone far away, and his faint song is still distinctly
audible from the house.
In some dark manuka thicket his pear-shaped nest is built, or deeply
set in some dense branched bush. The nest itself is not unlike that of
the British long-tailed tit, similar in the neat finish and feather lining,
but our New Zealander has often a tiny portico above, or little ledge beneath,
his entrance hole. The five or six eggs are sometimes almost quite white,
sometimes they are freckled like a wren's, with tiny spots at the thicker
end. The warbler sits close, and often when feeling for eggs or young I
have touched the old bird in her nest. The youngsters grow with great rapidity,
and for some time after quitting the nest they may be seen all together,
haunting the vicinity of their old home. Watching the parents and brood
together thus in a family party, the young able to feed themselves, though
still accepting food and all very merry and lively and busy, gives the
impression that this last week of companionship must be one of the happiest
episodes in the lives of parent birds. The cares and dangers of incubation
are past, the labours of feeding and rearing over, whilst there still remains
just sufficient responsibility to excite the parental instincts. The young,
like children to whom each hour provides new matter of wonder and interest,
are content in the exercise of their new developed functions, their facile
captures and brief flights.
Then comes a day at last when the warblers begin to think of their second
nest, and again in early summer, as in early spring, couples may be seen
playing and fluttering in the glades, poised in the warm air, and again
may be heard poured forth at every stage of their courting tour that faint,
sweet, tremulous trill, so unlike the note of any other native bird. It
is this second nest that is often patronised by the shining cuckoo, for
the warbler, though so small a bird - only four inches long - is that barred
migrant's favourite host.
It is the warmth, perhaps, of the domed nest that tempts these tropical
sybarites, or may be their knowledge of the unwearied industry of the little
warblers.
The earliest nest I got this year was party constructed on August 19th,
and was but a few days in advance of many others. No doubt, therefore,
second nests would be in process of construction, or even finished, by
the date of arrival of the shining cuckoo.
This cuckoo arrives at Tutira during the first week of October. This
year he was first noticed only on the 8th, and heard at intervals up till
the 27th January.
