An Epic Journey: Breeding and Longevity

The most incredible fact about the Common Greenshank is that despite being widespread across Australia in the summer, they do not breed here!

• The Northern Nurseries: Every year, between March and April, the Greenshanks leave Australia and fly thousands of kilometres north along the East Asian-Australasian Flyway. They breed in the vast, boggy taiga forests and northern steppes spanning from Scotland, across Scandinavia, all the way to eastern Russia and Siberia.
• Ground Nesting: Arriving in the sub-arctic summer, they establish territories and engage in beautiful, tumbling display flights. They build their nests as a simple, shallow scrape on the dry ground near marshy areas. The female usually lays four pale green, heavily splotched eggs.
• Shared Parenting: Both parents share the 26-day incubation duty. The chicks are precocial, meaning they hatch covered in down and are ready to leave the nest and run within hours, taking advantage of the 24-hour Arctic daylight to feed rapidly.
• Longevity: For a bird that makes such an exhausting, globe-spanning flight twice a year, their endurance is astonishing. In the wild, they commonly live for 12 to 15 years, and some banded individuals have been recorded surviving for an incredible 24 years, returning to the exact same Australian wetlands year after year!

Fascinating Facts: Frantic Feeders and Mist Dwellers

• What’s in a Name? The scientific name of the Common Greenshank is wonderfully poetic. Tringa comes from an ancient word for a wading bird, while nebularia is derived from the Latin word for “mist”—a beautiful nod to the damp, foggy marshlands they love to call home.
• The Active Hunter: Unlike the Great Egret, which stands completely still to hunt, the Greenshank is highly active and nervous. They feed by picking, probing, and rapidly sweeping their slightly upturned bill through the mudflats. They are even known to suddenly dash erratically through the shallows, actively chasing down small fleeing fish!
• Night Fishers: Because their incredible migrations require so much energy, they cannot afford to stop eating when the sun goes down. Greenshanks are highly adept at foraging through the dark, using the sensitive tips of their bills to locate crustaceans, molluscs, and worms in the nighttime mud.

Conservation Status and Environmental Threats

While the Common Greenshank is classified as Least Concern globally, their story within Australia has recently taken a deeply concerning turn. In early 2024, their conservation status under the Australian EPBC Act was officially upgraded to Endangered.

Extensive monitoring has shown their population numbers dropping by over 50 percent in recent decades. The primary cause of this decline isn’t happening in Australia or Siberia, but right in the middle of their migration route. The massive, rapid reclamation and industrial development of crucial coastal mudflats along the Yellow Sea in East Asia has destroyed the vital “stopover” refuelling stations these birds desperately need to survive their global flight. Locally, they are also threatened by the draining of Australian wetlands and constant disturbance by humans and unleashed dogs on our beaches.

What Can We Do to Help the Species?

Protecting migratory shorebirds requires a global mindset, but local actions make a massive difference. Here is how we can help the Common Greenshank rest and refuel on our shores:

• Leash Your Dogs: The single easiest way to help our migratory shorebirds is to keep dogs strictly on a leash when walking near estuaries, mudflats, and coastal lagoons. When a resting Greenshank is chased into the air, it burns the precious fat reserves it desperately needs to fly back to Siberia.
• Keep Your Distance: If you are birdwatching, kayaking, or fishing, admire these wary birds from a distance. If they start bobbing their heads nervously or calling out, you are too close.
• Support Wetland Conservation: Advocate for the protection of local coastal saltmarshes and inland wetlands. These quiet, muddy fringes are the vital dining rooms that sustain our global nomads throughout the long Australian summer.
