"From the start of bird control with distress calls in the Bird Gard, crows virtually abandoned 2 almond orchards in Yolo County and remained away from 3 other almond orchards in Sutter County for periods ranging from 9 to 30 days. Damage decreased at all sites compared to 1997. Almond losses ranged from $22/ac to $138/ac in 1998 compared to $46/ac to $1,015/ac in 1997. The decrease in damage represented significant dollar savings of $998, $3,642, and $5,914 for the three individual orchards," Paul Gorenzel, Horticulturist.

"The Bird Gard is very trouble free. In fact, it's more trouble free and less expensive to use than the crow guns...One of our foremen was in the grove and saw a flock of crows flying in. The unit went off at about that time, and the crows immediately turned in mid-air and left....A few days later the foreman said,'Notice how quiet the area is.' I had to admit it was pretty still. Normally we constantly hear blue jays squawking, but their presence was greatly reduced," Dr. Richard O'Barr.

"The Bird Gard Electronic Repeller with the gull chip (for crows) did a good job of changing crow feeding areas. The Bird Gard disrupted the crows and they moved to other areas. The way I used the Bird Gard was effective for about a week and then it had to be moved to another area," Dr. Thomas Crocker, Horticulturist-Pecans.
