Singapore authorities are facing a sharp increase in the number of crows in the city. According to Channel News Asia, the bird population has grown from approximately 7,3 thousand  in 2016 to approximately 160 thousand by 2024—resulting in one crow for every 38 residents of the city-state.

At the same time, the number of complaints from city residents has increased: in 2025, approximately 15 thousand were received—triple the number in 2020. Residents report noise, pollution, and aggressive behavior by birds. The number of attacks by crows has also increased: last year, more than 2 thousand cases were recorded, compared to approximately 460 a few years earlier.

Experts note that this primarily concerns the so-called house crow, an invasive species not native to Singapore. These birds are highly intelligent, capable of learning from each other, and quickly adapt to new conditions, including attempts to capture them.

Experts believe that one of the key factors driving the population growth is food availability. The expansion of the food service industry, as well as the tray and utensil collection system introduced in recent years, have provided birds with easy access to food scraps. The lack of natural predators in the urban environment has further contributed to the sharp increase in crow numbers.

To curb the population, authorities are implementing a range of measures: dozens of nests are removed daily, and more than 13 thousand birds were caught in 2025. After a six-year hiatus, culling has also resumed in some areas. However, experts acknowledge that these measures are not yet producing sufficient results: crows quickly learn to avoid traps, and the effectiveness of individual methods remains limited.
