Laser bird deterrent effectively reduces blueberry loss caused by birds

Inés Espinoza is the manager of Agrícola Calandria blueberry farm. The blueberry farm experienced severe damages to their blueberry crops with the Chilean eared doves. To reduce their dove problem in an effective and environmentally friendly way, Agrícola Calandria decided to install an Agrilaser Autonomic, an automated laser bird deterrent.

“Birds have always caused issues at our blueberry farm. This year we have harvested more blueberries than the previous year. We already exceeded a production of 50,000 kg of blueberries with additional 2,000 kg to be harvested. We have never had this before. This means that the Agrilaser Autonomic works very well and shows great results!”, says Inés.

Inés adds: “I went to the blueberry field several times after the Autonomic’s installation and there were a few doves. Normally the birds cause a lot of damage but compared with this year the damage was reduced to a minimum. We managed to save more blueberries this year as well as drastically reduced damage to branches, leaves and blueberries themselves.”

Before installing the automated laser bird deterrent Inés Espinoza had tried many other bird deterring methods including classic scarecrows and plastic ribbons that make sound in the wind. These ribbons were attached to the bamboo across the field. Inés says: “It didn’t work, the bamboo bothered us during the harvest and it looked terrible.”

“The laser projects the green laser beam which is perceived by birds as physical danger. This makes the birds fly away. “I will continue using this laser technology and service. Last year we exported 20,000 kg of blueberries, this year after the Autonomic’s installation we exported 38,000 kg.”

Plant age (years) Production (kg)
8 years 38,000 kg
9 years 40,000 kg + 5 %
10 years 42,000 kg + 5 %
11 years (without Autonomic) 52,000 kg + 19 %

Fertilizations are similar every year. The irrigation has never failed. The only difference this year with the rest of the years is the Agrilaser Autonomic.
