The present disclosure concerns a modular bird dispersal system, comprising: a photonic beam module having a light source to generate an output beam, the photonic beam module further comprising a control unit for controlling the light source. The system further comprising a receiving module having a physical connector, for reversibly connecting to a matching counterpart connector on the photonic beam module, wherein the physical connector and matching counterpart connector are arranged to, when connected: align the photonic beam module within a pre- defined position; electrically connect a plurality of spaced connection pads with matching connection pins to form electrical connection between the photonic beam module and receiving module: and at least partly dissipate heat generated by the light source to the receiving module.
