Written Answer by Ministry of National Development on measures adopted by NParks to control the population of birds in HDB housing estates

Aug 2, 2021

Mr Zhulkarnain Abdul Rahim: To ask the Minister for National Development (a) what are the measures adopted by NParks to control the population of birds in HDB housing estates or assist in the relocation of birds in a sustainable and humane way in order to reduce the noise disturbances caused to residents in areas where there is an over population of birds roosting in trees; and (b) whether NParks is studying other innovative ways or collaborating with other agencies in such measures.

Answer: 

NParks adopts a holistic, science-based approach to manage the population of birds in Singapore, comprising measures such as habitat modification, food source reduction, and population control. 

At HDB housing estates, NParks carries out habitat modification, such as the directional pruning of trees. The intent is to deter birds such as crows and mynahs from perching, and to break up large roosts. NParks also works with Town Councils to remove the nests, and to replace certain tree species with suitable ones to discourage roosting. In addition, NParks carries out studies to understand the ecology of birds, such as their roosting patterns and movements, to support its bird management strategies. 

To reduce the availability of food sources, NParks works closely with SFA, NEA, and Town Councils to encourage proper food waste management at food establishments around HDB housing estates, and to enforce against littering and illegal bird-feeding. NParks also partners agencies and Town Councils to educate the community on proper refuse management. 

NParks will continue to work closely with agencies to enhance its bird management strategies to reduce bird-related disamenities, such as noise disturbances caused to residents.
