I've never had my phone
turn itself off with the warning message that it was not built to
operate at such temperatures. This happened on Monday, when a heat-wave seared the greater Port Elizabeth area. Addo recorded 48
degrees; while our 'cool' fynbos site was 38. Its been a while since
I've felt so uncomfortable, with a cold shower the only relief from
the heat.
Jerry Mokgatla, Cape
Sugarbird Masters student from Polokwane (up north), was happy that
it was warmer. It also meant we caught no Cape Sugarbirds at his
study site on Lady's Slipper, although we'd set the nets up
relatively late, arriving on site at 7.30.
Ben Smit, Jerry's
supervisor had joined us for the morning, and was also keen to help
out with some Buttonquail surveys. There had been a fire in the area
a few years earlier and the veld looked promising. However, our short
mission did not result in any success, only the loss of copious
amounts of sweat. Ben did find some chameleons to keep us entertained.

Tuesday morning Jerry
and I were up on our way to Lady's Slipper at 4am, operating out of
Van Staden's wildflower reserve. Weather was overcast, but by the
time we got to our ringing site the wind was howling. Opening nets
was out of the question. We sat in the car for 2 hours hoping for a
break, but none was to be had. There was no sign of any sugarbirds
either. We spent the rest of the morning scoping out the Longmore
forest in the hope of finding more suitable buttonquail habitat, but
without success. In the afternoon we conducted some behavioural
observations on sugarbirds as part of Jerry's work to understand how
Cape Sugarbird foraging is impacted by temperature. Protea mundii are
just starting to put on a show at van Stadens and we had good views
of the birds going about their busy social agendas.

Wednesday we finally
managed to net some sugarbirds – all females and subadults. Ben had been worried about a sex bias
towards males, but this session definitely evened out the ratios.
However, the session would end early with the arrival of some
persistent rain that lasted the rest of the day. A couple of Victorin's Warbler were the highlight of the morning:
Luckily for me I would
not have to spend any more nights in my tent as ECPTA and the
wonderful management and staff at Groendal Nature Reserve had laid on
the Rooikrantz self-catering cottage. This has to be by far and away
the most luxurious accommodation I've stayed in as part of the
buttonquail surveys.
On Thursday morning we
had the crack team of rangers assembled (and Brian) to help with an
ambitious survey of the upland plateaus that form the foothills of
the Groot Winterhoek mountains in these parts. We were optimistic
since the habitat is basically an extension of what we had been
surveying in Baviaanskloof, where we had been very successful with
finding Hottentot Buttonquails. After our ascent of 10 Stop Hill
(which I was told 3 times in one day is called that for a reason) we
reached the plateau with the first veils of rain, which would keep us
company for the rest of our 7 km survey.
The first birds up were
Common Quail, but shortly after we had a potential buttonquail
sighting. And then another buttonquail and another... but now our
challenge was not so much if we were seeing buttonquail, but if we were
seeing the right one! Hottentot Buttonquail have not been officially
recorded this far east before, despite suitable habitat. According to
range maps this is were Hottentot Buttonquails end and Black-rumped
Buttonquails start. We were in perfect HB habitat: 3 year old, flat
fynbos.

It was time to call in
the expertise of resident expert ornithologist Ben Smit. Ben is
familiar with Black-rumped from KZN, but has yet to officially tick
off a Hottentot Buttonquail.
Friday morning finally
dawned with balmy weather: temperatures in the 20s and sunny. Ben
together with two of his students Nick and Anthony joined us with the
rangers (and Brian). Expectations were high as we were basically
surveying the adjacent plateau to the one from the previous day.
However, 4.5km later and all we'd registered was a Common Quail.
Despite being superficially similar from a distance, the plateau had
a higher grass component and resulting increased vegetation coverage,
despite being the same age in terms of fire recovery time. Really,
the habitat was perfect for Black-rumped Buttonquail, but without
any.

We would like to
express our heartfelt gratitude to Khayelihle Ncube for use of the
superb Rooikrantz cottage in the Groendal Nature Reserve, Brian
Reeves and the ECPTA for organising and paying for everything, and of
course the rangers who got their feet very wet during the long
surveys across the fynbos plateaus. Also apologies to Ben Smit and
the NMMU team for being called out under false promises of a
guaranteed Hottentot Buttonquail sighting! Still, this site is very
likely the end of suitable habitat and hence the range of our
enigmatic endemic, and the data gathered will help us immensely in
our modelling of range and habitat suitability.
