We arrived at Christchurch and after collecting
our hire car, armed with instructions from local scientist and conservationist John
Dowding, headed for Black Stilt country, as we sped anxiously through the
pastoral landscape that New Zealand’s South Island has become, amazed at the
sheer numbers of Yellowhammers we were seeing, we saw our first Wader Quest
tick, South Island Pied Oystercatcher fondly known as SIPO to the locals.

We arrived at the southern end of Lake
Tekapo. As we drove past the first part of the shore visible I spotted two
stilts, and they looked dark. Pulling over rather more quickly than normal I
soon had my bins on the two stilts, as did Elis, and we found to our
consternation that they were hybrids, Black / White-necked Stilts. This is one
of the major concerns among those that are trying to save the Black Stilt from
extinction, the amount of hybridization that goes on within the two species
diluting the pure black DNA.

As we prepared to drive away a movement
caught my eye just below the car, on inspection it turned out to be rather more
pleasing than the stilt hybrids, a second Wader Quest tick, Double–banded
Plover, and what a tick it was, a beautiful bird.

From there we headed for Lake MacGregor and
seeing nothing remotely stilt like drove on to Lake Murray. At Lake Murray we
saw a full White-headed Stilt but no Blacks. Returning to Lake MacGragor we
renewed our efforts but still to no avail so we left. Having driven all of 100
yards Elis, as calmly as you like, almost whispered in an understatement to end
all understatements “I’ve found your bird.” My first thought was ‘why my bird?’
but without dwelling on this curious statement I leapt from the car in time to
see two beautiful black Black Stilts fly across my field of view!

This was fantastic and we watched them land
again and got some record shots and then saw them fly over some trees to the
other side of the road. We followed them but found just one. This individual
showed some white feathers in the under tail and around the face. I suddenly
became concerned about its ‘purity’.

I decided the best thing to do was to try
and find some more so we headed for Glentanner. Arriving at the site we had
been given we noticed a car parked out near the braided river system and a lady
walking around, we then noticed that there were several stilts flying around
her. We drove down to join her and see what was going on. We found that this
lady, Femme by name, was feeding recently released birds as part of the captive
breeding programme.

Intriguingly there was an all black adult
bird there too, Femme said this was a bird that had been released a number of
years ago (not sure exactly how many), but it knew when it was onto a good
thing and kept returning for a free feed.

We talked about the birds we had seen and
the concerns I had about them being pure. Femme asked to see the photos Elis
had taken so we obliged and she looked with interest at them, comparing them to
a chart she had of plumage variations. She seemed to be suggesting the bird was
looking good, then she saw the rings. “Its colour-ringed, that means it is 100%
pure, they only ring pure birds in the programme, it is probably just not quite
a full adult.” We were much relieved to find the birds we saw were pure. Some
will argue the ethics of ticking released birds, but for the purposes of Wader
Quest, quite frankly who cares? The point is, thanks to wader conservation,
they still exist!

After enjoying the close proximity of the
birds for some time Elis and I went for a wander and, to our complete joy,
found a Wrybill pair along the nearest stream of the braided river.

Our first Wrybill Anarhynchus frontalis. |
What a day this had been! Our first day in
New Zealand and we had seen four of our targets including what is probably the
rarest wader in the world, Black Stilt and the incredible, amazing and unique
Wrybill.
