Scare birds from fish farms
A before-and-after trial at 25 fish ponds in a catfish farm over 45 days in February and March 1992 in the Mississippi delta region, USA (Stickley & King 1995), found that using a ‘Scarey Man’ resulted in a rapid decrease in double-crested cormorant Phalacrocorax auritus numbers (320 birds/patrol before treatment vs. 8/patrol for the first seven days after erection and 16/patrol for the whole 46 day experiment). Clothing the devices to resemble marksmen, replacing them with actual marksmen and using propane gas exploders (at up to six Scarey Man positions for 23 days) did not further reduce cormorant numbers.
