The Cranes of the Forest: An Australian Story

The habitat that first comes to mind when we refer to cranes is wetlands. We immediately think of an expansive amount of water dotted with lilies and lotus, bordered by swaying reeds in which a heron or two skulks, accompanied by the symphony of frogs.

For the Sarus Crane, the imagery is more diverse. In South Asia, these cranes live and nest amid flooded rice paddies, never far from the humdrum of a north Indian village, its farmers and their cattle. They also use the community-owned wetlands on the riverine floodplains, where they are joined by a multitude of waterbird species, alongside cattle, pigs and farmers.

The habitat of breeding cranes in Australia is rather different. The Sarus shares their breeding areas with Brolgas in the region of northern Australia bordering the Gulf of Carpentaria. Here, they breed in woodlands!

These three young Sarus Cranes search for food in an artificial borrow pit along the road.

Along with local ecologists, crane experts, collaborators and colleagues, I visited Australia in April and May this year to understand how the cranes are faring. It was a very different world indeed than the one I am used to in South Asia.

Tall grasses and other vegetation frequently necessitated that we get on top of our vehicle to count cranes.

Much of the land is held under long-term leases, with owners using the mixed grasslands, wetlands and woodlands, primarily of Eucalyptus, to graze millions of cattle. They also need places where the cattle can drink. These areas are provided by either naturally flooded depressions, or artificial ones, which the cranes also have adopted.

Artificial water holes made for cattle serve as habitat for many waterbird species like these whistling ducks, as well as both Sarus Cranes and Brolgas.

We counted over a thousand Sarus and Brolga during our survey, where we covered nearly 3,000 kilometers. We saw that many of the pairs had managed to raise chicks, and we witnessed wonderful, noisy flocks of both crane species jousting on the cattle ranches.

Sarus Cranes are infrequently seen in grasslands, but some pairs do breed in these open, non-woody habitats.

Brolgas use several grasslands where thousands of cows graze.

The forests, we also discovered, were a fantastic repository to a multitude of unique wildlife. We had to stop our vehicle many times to allow bustards displaying to each other. Massive flocks of pigeons feeding on the roads also halted us. We counted thousands of falcons and kestrels, several of which were following cranes walking through the grasses to pick up the insects that the cranes disturbed.

Evening drives across the grasslands are slow due to the wildlife, which at times included several displaying Australian Bustards kicking up the dust.

A very pleasant break from constant driving across grasslands were massive flocks of the stunning Harlequin Bronzewing Pigeons.

Animals were largely unused to vehicles, and we saw many road kills. These, in turn, attracted the wedge-tailed eagles and other raptors turning our driving into a refreshing opportunity to watch fantastic wildlife.

Road kills of wallabies and kangaroos attract many raptors, including the majestic Wedge-tailed Eagles.

We swerved away from Wallabies and Kangaroos on the roads, slowed down to allow flocks of brightly-colored Galahs to fly away, screeched to a halt as frill-necked lizards displayed valiantly at our vehicle, and watched in awe as gigantic monitor lizards moved across the grasslands looking for something to eat.

Agile Wallabies are abundant and not yet clued into the dangers of the road and traffic.

With a killing color combination of pink, grey and white, the Galah was easily one of the most attractive cockatoos we saw.

The largest mammals we saw were the Red Kangaroos, whose family groups included wobbly joeys that had recently emerged from their parents’ pouch.

The Frill-throated Lizard is an iconic Australian species, and we were fortunate to see several during our survey.

Huge Monitor Lizards roam the grasslands and woodlands of the Gulf and we frequently saw them watching us quietly from behind the vegetation.

The Sarus’ breeding areas in Australia, we realized very quickly, were much more than just crane areas. They were in part ancient in having lizard and bustard habitats, and in part recent in being modified for cattle and ranchers, proving to be useful for cranes.

Few vistas are as stunning as the natural marshes that are bounded by termite mounds and woodlands, with yellow and white lilies floating on the water surface.

The cranes of the forest have opened up a world that is exciting, somewhat untouched despite being heavily modified, and hosting a diversity of flora and fauna that is uniquely Australian. With this post, we are thrilled to announce our new foray into Australia where we will work with several Australian colleagues and institutions over the coming years. Together, we will seek to learn about the wonders of this glorious landscape, and collaborate with the hard-working people of the Gulf region to conserve the cranes.

This work was initiated with the support of donors in Australia, matching grants provided by the University of Melbourne, and support from the Nature Conservation Foundation. Our partners in this initiative are Australian ecologist John Grant and crane expert Elinor Scambler, colleagues at the University of Melbourne, Inka Veltheim and Michael McCarthy, and Swati Kittur from the Nature Conservation Foundation. To all, I am beholden for their interest, help, and partnership, and look forward to a long-lasting collaboration.
