The Eurasian tree sparrow was the most notable target of the campaign.

The Four Pests campaign (Chinese: ; pinyin: Chú Sì Hài), was one of the first actions taken in the Great Leap Forward in China from 1958 to 1962. The four pests to be eliminated were rats, flies, mosquitoes, and sparrows. The extermination of sparrows is also known as smash sparrows campaign (Chinese: ; pinyin: què Yùndòng) or eliminate sparrows campaign (Chinese: 消灭麻雀运动; pinyin: Xiāomiè Máquè Yùndòng), which resulted in severe ecological imbalance, being one of the causes of the Great Chinese Famine. In 1960, Mao Zedong ended the campaign against sparrows and redirected the fourth focus to bed bugs.


The "Four Pests" campaign was introduced in 1958 by Mao Zedong, as a hygiene campaign aimed to eradicate the pests responsible for the transmission of pestilence and disease:

  • the mosquitos responsible for malaria
  • the rodents that spread the plague
  • the pervasive airborne flies
  • the sparrows—specifically the Eurasian tree sparrow—which ate grain seed and fruit[1]


The government also declared that "birds are public animals of capitalism".[2][better source needed] Sparrows were suspected of consuming approximately four pounds of grain per sparrow per year.[3] Sparrow nests were destroyed, eggs were broken, and chicks were killed. Millions of people organized into groups, and hit noisy pots and pans to prevent sparrows from resting in their nests, with the goal of causing them to drop dead from exhaustion.[3][4] In addition to these tactics, citizens also resorted to simply shooting the birds down from the sky.[5] These mass attacks depleted the sparrow population, pushing it to near extinction.[5]

Some sparrows found a refuge in the extraterritorial premises of various diplomatic missions in China. The personnel of the Polish embassy in Beijing denied the Chinese request of entering the premises of the embassy to scare away the sparrows who were hiding there and as a result the embassy was surrounded by people with drums. After two days of constant drumming, the Poles had to use shovels to clear the embassy of dead sparrows.[6]


By April 1960, Chinese leaders changed their opinion due to the influence of ornithologist Tso-hsin Cheng[2] who pointed out that sparrows ate a large number of insects, as well as grains.[7][8] Rather than being increased, rice yields after the campaign were substantially decreased.[8][9] Mao ordered the end of the campaign against sparrows, replacing them with bed bugs, as the extermination of sparrows upset the ecological balance, and insects destroyed crops as a result of the absence of natural predators.

By this time, however, it was too late. With no sparrows to eat them, locust populations ballooned, swarming the country and compounding the ecological problems already caused by the Great Leap Forward, including widespread deforestation and misuse of poisons and pesticides.[9] Ecological imbalance is credited with exacerbating the Great Chinese Famine, in which 15–45 million people died of starvation.[10][11] The Chinese government eventually resorted to importing 250,000 sparrows from the Soviet Union to replenish their population.[12]

Revived campaign[edit]

On June 19, 1998, a poster was spotted at Southwest Agricultural University in Chongqing, "Get rid of the Four Pests". Ninety-five percent of households were ordered to get rid of four pests. This time, sparrows were replaced with cockroaches.[7] A similar campaign was spotted in the spring of 1998 in Beijing. Few people responded to these campaigns, as many already had the habit of killing the aforementioned pests, especially cockroaches.[7]

Cultural influence[edit]

In the 2009 TVB drama series Rosy Business (set in mid-19th-century China), a peasant came up with the idea of killing the sparrows to improve agricultural output. It was meant to be a prank used to trick the peasant owners into starvation and poverty.

The smash sparrows campaign is mentioned in the 1960 Michael Carreras movie Passport to China. In a brief scene, people are shown using fireworks to make the sparrows ascend.

In episode 20 of the 2001 children's animated television series Sagwa, the Chinese Siamese Cat (set in China around 1900), the mistress of the house declares that certain useless animals are banned from the compound. After the animals—the episode's eponymous birds, bees, and silkworms—are driven out, the family discovers the consequences. The mistress's fancy banquet is ruined by the lack of food and clothing, and she learns a valuable lesson.

The album Every Red Heart Shines Toward the Red Sun (2006) by the American post-rock band Red Sparowes tells, by way of its song titles, the story of the great sparrow campaign.

The children's book Sparrow Girl (2009) by Sara Pennypacker tells the story of the sparrow war.
