Pigeons on your HDB aircon ledge: what can you do?

Pigeon problem HDB: why pigeons pick your ledge

An aircon ledge is flat, sheltered and out of reach, so it is an easy place for a bird to rest. When someone in the estate feeds birds, pigeons have food close by and a quiet ledge to come back to. Droppings, feathers and nesting material then build up where you cannot easily reach them.

The Ministry of National Development (MND) has set out how the issue is handled across estates. In its written answer on pigeons at air-conditioner ledges, MND said NParks manages pigeons through population control, habitat modification, enforcement against illegal bird feeding and education.

That list is a useful way to think about your own flat. Pigeon numbers are not something you can control, but you can play a part in the rest:

• Habitat: make your own ledge a less comfortable place to settle.
• Enforcement: report feeding so NParks can look into it.
• Education: knowing why pigeons settle on ledges helps you and your neighbours avoid attracting them.

Report feeding

Feeding is the part of the problem you cannot fix from your own window. OneService says bird issues reported through it are assessed by NParks through site visits, monitoring or surveillance. It also notes that feeding pigeons is an offence under the Wildlife Act, and asks you to share the timing of feeding or the feeder's identity with NParks if you know them.

In a written answer on enforcement against bird feeding, MND said that under the Wildlife Act, feeding any wild animal, including birds, can draw a fine of up to S$5,000 for a first offence and up to S$10,000 for later offences. The same answer encourages feedback providers to give detailed information and evidence of feeding.

A pigeon feeding report is more useful when it is specific. Note where the feeding takes place, what time of day it happens and how often you see it. Leave enforcement to NParks rather than approaching the feeder yourself.

For the steps to file a report, see how to report estate issues through OneService.

Make the ledge less inviting

Start with what you can reach safely from inside the flat. Clear away twigs, leaves and other nesting material as soon as you see them, and keep the ledge clean so droppings do not build up. Do not leave food, pet food or open rubbish anywhere birds can reach, including the window sill.

Netting and other deterrents are a different matter, because they are fixed to the outside of the building. In the same written answer on air-conditioner ledges, MND said NParks and HDB will trial deterrent measures such as bird nettings in consultation with Town Councils. It also said there are no plans to change the Home Improvement Programme for this.

Cleaning droppings safely

Clean only what you can reach from inside the flat, with both feet on the floor. A simple routine keeps the job tidy:

• Wear gloves and a mask before you start.
• Wet the droppings with water first, so they lift off as a paste rather than as dry dust.
• Scrape or wipe them into a bag, tie it and throw it out with your household rubbish.
• Wash your hands when you finish.

Avoid pouring or hosing water off the ledge, as it can drip onto windows, laundry and people below.

The same habits apply to any work at the window, so it is worth reading how to clean windows safely in an HDB flat before you start.

Aircon units on the ledge

A pigeon aircon ledge problem often reaches the outdoor unit too, because the unit sits right where the birds rest. Droppings can collect on the casing and around its base. Do not try to clean the unit yourself through the window, and do not open its cover.

Instead, ask your aircon technician to clean the unit and the area around it during a routine aircon maintenance visit. Mention the droppings when you book, and ask whether this cleaning is included or charged separately, as the price depends on the job.

Pigeons may also gather in shared spaces outside your flat. Before you place anything in the common corridor to keep them away, check the corridor rules for your block.

Who handles what

Each part of the problem has a different owner. Bird issues go through OneService, where NParks assesses them, and NParks manages pigeons through population control and other measures.
