Preliminary studies conducted in the field of ultrasonic broadcast for bird pest control has identified among others, that ultrasound of specific frequencies and certain audio sounds can serves as effective parameters in weaver bird pest scaring. Of interest is ultrasound frequency of 35 kHz as the put-to-flight and stay-away frequency in bird homes, while 25 kHz holds in farm conditions. These findings set the stage for this work which is aimed at determining the compositions, dimensions and specifications of a stand-alone device capable of electronically generating ultrasound of the required frequencies and incorporating audio sounds of predators to effectively scare weaver birds away from farms while overcoming the challenge of habituation. The design consists of sections as: the solar power supply, tripping, timing, oscillatory, frequency selection, amplification, microcontroller, predator cry, LCD and ultrasonic transducer sections and their respective circuits. The design if implemented and tested, will ensure 360o horizontal ultrasound coverage and a vertical boost to effectively repel weave bird pests from the vicinity of broadcast.
