Driving south on the Silver City Highway we
stopped for morning tea about 30km north of Broken Hill at Yanco Glen, a ruin
beside the highway and just up stream of a creek crossing. Stepping from the
vehicle I was struck by a distinctive bird call I recognised immediately,
Chirruping Wedgebills, even though I have only seen these birds twice before.
The birds at this stage were calling from within the abundant saltbushes
surrounding the ruins of an old building now reduced to not much more than
foundations with remnants of the building and occupation scattered here and
there.
Postponing morning tea I grabbed the camera
and went to investigate.
Curiosity soon got the better of one bird, which appeared at the top of a nearby saltbush. |
There are two species of Wedgebills, Chirruping
and Chiming, both are birds of the arid inland and are closely related to
Whipbirds with which they share a number characteristics including crests, long
tails, strong feet and a preference for dense vegetation. Both forage on or
near the ground, both are shy and somewhat reclusive and both have distinctive
calls which often give away their presence.
The rakish crest definitely adds character to these otherwise plain brown birds. |
The Chirruping and Chiming occupy an
eastern and western range respectively, which stretches right across central
Australia to the WA coast with an overlap in the Simpson Desert. Chirruping
Wedgebills were once found in Victoria where they are now extinct. A check of
my copy of the Victorian Biodiversity Atlas database shows one pre 1900 record
near Swan Hill and a 1900-1949 record west of Mildura.
While these birds may have a large range
and be locally common, from my experience they are not encountered very often
and when they are found it is often due to hearing their distinctive calls.
Both species are very similar, however their
calls are very different and Chiming is much more shy. Both species will call
incessantly for long periods from a high vantage point however the Chiming
ceases calling and retreats to cover readily when disturbed while the
Chirruping is more approachable and is more likely to keep on calling when
approached. Also the Chirruping songs often involve male and female duets
whereas the Chiming does not do this.
Both species respond readily to call
playback but only to their own calls, which was one of the ways researchers
were able to work out there were two species and not one as originally thought.
At Yanco Glen, based on their calls and the
appearance of birds here and there among the saltbush, it soon became apparent
there were at least four or five birds in this area. And true to their nature
one soon flew up to the top of a dead tree and commenced calling.
The brisk wind did not deter this bird singing from a high and exposed perch. |
Males and females look identical - I suspect this is a male on basis that it is most likely the males that call from high perches. |
Note the long tail and short wings, these birds are not strong fliers and mostly run between clumps of saltbush and make short flights occasionally. |
I was pleased to find this species again,
albeit by shear chance, and pleased to get some photos.
It was interesting to read this post as we stopped there on our way north to Innamincka and saw several species, but didn't hear or see Wedgebills there, although we did see some in Sturt National Park a couple of days later. The photos make it well worth the postponed morning tea!
ReplyDeleteThanks for the comment, glad you caught up with some Wedgebills in Sturt NP.
