For 16 days this July, I had an adventure in the Australian
outback. It had a road trip. It had camp cooking. It had sand dunes and
scrubland and bush walks and hot springs and country towns and dragons and a
marathon, and it had birds – lots and lots of birds.

To be specific, I was lucky enough to be included on a remote field trip to survey birds in inland Australia for Dr Richard Fuller’s Spatial Ecology research group. I accompanied Master Birders Claire Runge and Nick Leseberg for two weeks of surveying along the Birdsville track, starting in Adelaide, South Australia and ending up in Birdsville, Queensland. I was primarily the expedition’s chef and scribe, but by the end of our trip I believe I had earned the rank of Novice Birder, seeing a total of 67 “lifers” (birds I’d never seen before) and starting a bird list of my own.

By
combining the results from their long-term surveys with remotely sensed data on
weather and climatic conditions, the Fuller lab aims to determine how the
distribution of birds in Australia’s remote regions is altered by climatic
change. The surveys conducted along the Birdsville and Strzelecki tracks will
also help us figure out exactly what birds are out there and where they go as
the seasons change.

a night of raptorish activity. Letter-winged Kites are uncommon and nomadic,
and sighting numbers are further decreased by their nocturnal life history.

The Gibberbird (Ashbyia lovensis),
a type of Australian chat only found on the gibber plains.
|
As we made our way across the country, we saw some amazing
things. Some nights were spent camped out on gibber
plains, without a single shrub in sight – a situation that was far more comfortable
than you might imagine. In the mornings we found Gibberbirds, smooth-snouted earless
dragons, and lots of old hand tools made by indigenous people long ago. We also
found a nesting Inland Dotterel, faithfully sitting on her eggs until we
unwittingly almost walked over her, when she leapt up and played the bird with
the broken wing until we’d moved away.

look big. Most of the insects and reptiles out on the gibber plains are well
camouflaged.

Nesting Inland Dotterel (Charadrius australis), sitting
steadfastly on her four, well-camouflaged eggs.
|
Other nights we camped at Artesian hot springs, lush with
vegetation and bird life. Here we got to hang out with Pied Stilts,
White-breasted Woodswallows, Black-fronted Dotterels, Whistling Kites, along
with hundreds of Galahs who shacked up for the night above our tents.

It
wasn’t just the fauna that amazed me – the adaptations of the plant life to
such a harsh environment blew my mind. We surveyed at salt plains that looked
like a scene from the bottom of the sea, or a kind of terrestrial coral reef.
We trekked amongst the saltbush, including the chenopods with their
spectacularly aggressive seed pods (seriously. Those things hurt!), Acacia and Eucalypt woodlands and Spinifex grasslands. We also found some furry trees
along a riverbed, which turned out to be Acacias with minni ritchi, a type of
reddish-brown bark that continuously peels back from the stem.

Samphire (Tecticornia sp.), a salty succulent that comes in all different
colours and shades and looks kinda like a sea anemone.

With its leaves and flowers in
different shades of green, with its huge succulent seed pods – I have no idea
what this plant was, but it was beautiful.

bark that continuously peels back from the trunk and branches, giving the tree
a furry appearance).
|
Despite the beauty of the places we were travelling through,
there were some chilling reminders of some of the problems the ecosystem out
there faces. The number of rabbits we saw was absolutely astounding – sometimes
it was all I could do not to roll an ankle in the massive tunnel networks
they’d created throughout some areas of the landscape. We also saw a
disturbingly high number of prints from feral dogs, cats and foxes, all of
which pose a massive predation threat to the small birds, reptiles and mammals
that live there (especially ground-nesting birds like Lapwings and Dotterels).
In addition, the degradation of the land by cattle and sheep was extremely
obvious at many of the sites we surveyed.

Fox prints in the sand. Foxes are an
invasive animal in Australia, and along with feral cats and dogs they pose a
major threat to small mammals, reptiles and birds.

All of these things made me appreciate how fragile the
balance of the ecosystem is. The research the Fuller lab is carrying out is not
only important in determining how climate change will affect species
distributions, but it also will help us determine where rare species like the
Chestnut-breasted Whiteface and the Letter-winged Kite occur, and therefore
which areas we should focus on conserving. We live in a beautiful world, with
an amazing amount of biodiversity even within our harshest environments. It
would be a shame to lose that biodiversity due to lack of knowledge and
understanding.

This trip was a fantastic experience for me, and one that I
know many people will never get to have. I am extremely grateful to the Fuller
lab for including me on this research trip, and to Nick and Claire for making
it so much fun. Thank you for the adventure!
