Forum: Smarter tray return systems can help manage crow numbers

The recent decision by the authorities to resume crow shooting operations has sparked debate online, with many Singaporeans expressing discomfort over the use of lethal force. While I share these concerns, I also recognise the tough job the National Parks Board faces. With the crow population rising to an estimated 160,000 and complaints about crow attacks surging to over 2,000 cases in 2025, residents do need to be protected.

However, returning to a method previously halted in 2020 due to safety risks comes off more as a reactive measure. Shooting targets the current crow population, rather than the easily accessible food supply that is the root cause.

The Animal Concerns Research and Education Society has shared that around 13,000 crows were removed in 2025 without firearms, yet the overall crow population still grew. This proves that culling doesn’t work if the crows’ primary food supply remains easily accessible.

I have seen that gathering food scraps into open tray return racks at local hawker centres inadvertently creates centralised buffets for the birds. While the National Environment Agency trialled automated anti-bird shutters at places like ABC Brickworks Market and Food Centre, the birds quickly figured out how to tailgate patrons as the doors slide open.

I urge the authorities to develop the next generation of bird-proof tray return systems. Potentially, we could upgrade these stations islandwide with existing technologies like double-door mechanisms, weight-activated flaps or faster-closing sensors to keep birds out.

I believe upgrading the food waste infrastructure is the most sustainable way to complement current non-lethal culling efforts. By designing smarter facilities, we can naturally reduce the crow population, ensure public hygiene and achieve our shared vision of a City in Nature.
