The large waterhole with copious lignum,
located on the Eyre Development Road about 40km south of Bedourie (or 125km
north of Birdsville), is another place where Grey Grasswrens (Amytornis barbatus) have been recorded.
The waterhole is on Eyre Creek, which runs
west and then south from the water hole eventually disappearing into the
Simpson Desert. This watercourse probably once discharged into Lake Eyre before
drifting sand dunes, which are now stable, cut off its course.
We camped on Eyre Creek for a night and
searched again for GGW in the afternoon and the morning - once again without
success.

ancient spreading Coolibah tree. |
There were a number of water birds on the
creek/waterhole including Pelican, Darter, White-necked and White-faced Heron, Yellow
Spoonbill the odd Eurasian Coot and Masked Lapwings.

View upstream from our campsite – note
the fringing lignum. |
This site had the most extensive lignum
stands we have encountered so far and the lignum was in good condition with
fresh green growth following recent rains. So one would expect that conditions
were ideal for Grey Grasswrens. However these birds are reputed to be very shy
and hard to find even when it is known they are present.
We found it hard to know how to go about
looking for them in such a vast area of lignum. In the end we adopted the
strategy of walking slowly by as many large lignum clumps as possible, stopping
frequently to listen for their calls which we thought they would make in response
to our presence, and thereby giving us a location where we might concentrate
our search.
At the same time we were also hoping we
would luck onto a bird that popped up to take a look at the intruders. Once
again all to no avail with not one single hint of a GGW after several hours
searching.
We did however find other species at the
location to enjoy and photograph.

White-necked Heron taking flight at my
sudden presence. |
|
First it flew one way – note the lignum
in background. |
|
Then it flew the other way eventually
landing some distance downstream |
|
Some Pelicans having a break from
fishing. |
|
Caspian Terns, our largest tern, are often
found on arid inland waterways and lakes, perhaps surprisingly for a bird we
think of as a seabird. |
There were also a good number of raptor
species at the water hole.
|
At first I thought this bird might be
the rare Letter-winged Kite as we were within its core range however when it
flew I could see no under wing black W
marking so it was a Black-shouldered Kite. |
|

look very similar to the Black-shouldered Kite, taken near the Birdsville Track
in August 2012. |

Female Nankeen Kestrel perched above
waterhole. |
|
Some of the 40 - 50 Black Kites in the
area. Unlike other raptors, this species seems to often gather in large flocks
to feed and roost. |
|
This Black Kite came in for a close
look at me. |
|
Curiosity satisfied the Black Kite soon
departed. The distinct shallow V tail, an easy ID feature, is clearly showing in this shot. |
While searching lignum in the early morning
we came across a Wedge-tailed Eagle resting in the top of an acacia tree
amongst a parasitic growth, perhaps a mistletoe species, which afforded good
cover and might explain why this bird did not move even when I approached quite
closely with the camera. The chance encounter briefly interrupted the GGW
search while I took some close up portraits of the Eagle.
|
Enjoying the early morning sun. |
|
The Eagle kept an eye on me but would not be budged from its perch. |
|
The Eagle was still there when we passed by half an hour later. |
We crossed paths on a number of occasions
with fast moving small flocks of Flock Bronzewing (a pigeon species). While
hunting for the Grey Grasswren at Eyre Creek two small flocks flew past with a
couple of distant photos captured. I would like to get some closer shots of
this elusive species one day.

small flock of about 15 birds. |
In the end, not knowing for sure if Grey
Grasswrens were present in the area we decided to give up on the search, after our
third unsuccessful attempt to find them. So our next move was north to Boulia
to stock up on fuel, water and food before heading west on the Plenty Highway
to Alice Springs.
