The Society has been commissioned by AFCD to conduct a survey on House Crow Nest in the coming two months. The purpose is to provide data to AFCD in order to reduce the number of this exotic species which may threaten the natural environment of Hong Kong. You are welcome to inform us the location of the nest through e-mail (hk bws@hkb ws.org.hk) or PM. Photos or map showing exact location is most welcome.
