Hong Kong has recorded a roughly 11 per cent drop in the number of feral pigeons found at common gathering spots after an expanded no-feeding law took effect, according to authorities who are planning to use artificial intelligence (AI) patrol robots to enhance enforcement.

The number of feral pigeons stood at about 12,090 during the first quarter of this year, down by about 11 per cent from around 13,520 in the previous three months, across 140 spots in the city where birds gathered or caused a nuisance, according to the Agriculture, Fisheries and Conservation Department.

Food left by people for the birds was found at 30 of the 140 spots during the first three months of this year, down from 37 during the fourth quarter of 2024.

The department carried out a citywide study over the two quarters, with researchers conducting on-site inspections and recording the number of feral pigeons spotted.

“As various departments continue to strengthen enforcement to combat illegal feeding activities, we expect the problem of feral pigeons gathering in urban areas and the nuisance they cause to continue to improve,” said Dr Jeremy Ho Hon-pong, senior veterinary officer of animal health at the department.

The Wild Animals Protection (Amendment) Ordinance 2024 took effect on August 1 of last year, expanding the citywide prohibition on feeding wild animals to cover feral pigeons.

The revised law is part of the city’s efforts to curb illegal feeding activities and improve environmental hygiene.
