A computer based bird control system is provided. The bird control system utilizes an impactor that is attachable to a structure, such as an I-beam or other similarly sized and dimensioned metal object, to create an acoustic impact noise similar to a whacking of the structure. The impactor is preferably actuated at a random or a semi-random impact rate such as around once every ten seconds. The acoustic impact noise may be provided in addition to the playing of bird predator or other deterrent sounds maintained in audio files on the computer. The system also provides audio and/or physical bird presence detection within a monitored area. Detection of the presence of a bird may be used as a trigger for the actuation of the impactor and/or predator/deterrent sounds. Actuation of the impactor and/or sound files may be accomplished via a schedule through the use of timer files in addition to or in place of animal presence detection. A graphical user interface of the system provides user control of the system including the ability to set and/or modify system parameters such as those that can detect particular bird species via audio detection, as well as the manipulation of timer file parameters for automatic or forced activation of the impactor and/or sound files.
