Abstract: A towable, single axle utility trailer having a support platform, a rearwardly angled frame at a front end, a support column at a rear end, control units on the angled frame to generate timed electrical signals representative of geese recordings of alert and alarm, audio speakers on legs of the support column for sounding alarms of multiple geese in motion and at different levels of distress, and a solar panel collector atop the support column for energizing a storage battery in providing the electrical power required to operate the speakers and control units.

Abstract: A towable, single axle utility trailer having a retractable tower supporting a sonic bird repeller at an upper end thereof, a solar powered panel coupled to charge a storage battery on a trailer platform, and an electric cabling connecting the battery to actuate the sonic bird repeller for providing predatory bird distress calls in creating a danger zone to frighten infesting birds away.
