⚫ In November 1929, as the world reeled from the stock market crash, a quiet and strange war was unfolding in Western Australia. Unlike the farcical emu standoff three years later, this campaign never made the headlines. It lacked the absurdist flair and wasn’t waged against giant flightless birds—but against cormorants, fish-eating fowl that local farmers and fishermen deemed public enemy number one. It was part of a sweeping yet little-known "National Protection Programme", and its weapon of choice was, once again, the Lewis machine gun.
⚫ The silhouettes of pelicans, swans, and cormorants—once teeming along the shallows of the Swan River—had grown ghostly by the late 1920s. Perth’s streets were adorned with bird-shaped lampposts, a silent memorial to lost biodiversity. But for authorities and farmers, cormorants weren’t symbols of a vanishing wilderness; they were a blunt threat to fish stocks and farmland. A hunt was declared, sanctioned at the highest levels.
⚫ The program operated on a simple, brutal principle: declare a species a "competitor" to humans and systematically wipe it out. The campaign against cormorants was justified under the Fisheries Act of 1905, which allowed bounties for the destruction of birds "hostile to fish life." Paradoxically, the same species could be protected under the Game Act of 1892, but bureaucratic logic prioritized economic interests over conservation.
⚫ The 1929 operation was a logical extension of the emu war, with one key difference: if emus were the "tanks" of the land, cormorants were the "guerrillas" of the waterways. Machine-gun crews—often the same soldiers who’d fought in earlier campaigns—faced tactics that today would be called ecological guerilla warfare. The birds scattered, exploited the shoreline’s terrain, and displayed astonishing resilience.
⚫ Success was measured the same way as in the emu war: body counts and bullets expended. Official reports claimed hundreds of cormorants killed, but the real impact on their population, as with the emus, was minimal. The birds kept nesting and feeding, their capacity for recovery outstripping the military’s ability to suppress them.
⚫ The climax of this story wasn’t a military victory but a quiet revolution in scientific thinking. While the gunners waged their war, scientists like ornithologist Dominic Serventy of CSIRO began gathering data that upended the narrative. They proved the real culprit behind dwindling fish stocks wasn’t the cormorant but large-scale land reclamation and the destruction of coastal shallows—natural spawning grounds.
⚫ Scientific reports from the 1930s became an indictment not of birds but of human activity. Cormorants transformed from "pests" into indicators of ecosystem health. Their disappearance from the Swan River wasn’t a triumph over a competitor but a symptom of ecological collapse driven by urbanization and agricultural expansion.
⚫ This shift in perception was slow and painful. Public debate gradually moved from "How do we kill cormorants more efficiently?" to "How do we preserve fragile habitats?" Machine guns gave way to scientific discourse, and the "protection" program revealed its true nature: it wasn’t about safeguarding nature but shielding economic interests from its consequences.
⚫ The failure of the 1929 campaign and subsequent attempts at a military solution led to a change in strategy. Authorities switched to a bounty system, which proved just as ineffective. By 1950, as parliamentary records show, the government authorized farmers to use .303-caliber army ammunition for DIY bird control, allocating 500,000 rounds for the purpose.
⚫ Yet by the mid-20th century, it became clear that the future lay in barriers and ecological management, not machine guns. The scientific community, led by figures like Serventy, finally convinced the government that sustainable solutions required habitat conservation, not the extermination of its inhabitants.
🧠 The war on cormorants isn’t a punchline—it’s a lesson in how easily we mistake symptoms for causes. We arm ourselves with machine guns against birds while the real enemy is our own short-sightedness. Cormorants, like emus, were just a mirror reflecting the contradictions of our drive to dominate nature. And in that mirror, we saw not our enemies but ourselves—creatures capable of great folly and, perhaps, great awakening.
