Crow Control Industrial Facility

Experience report of the BirdGard Super Pro PA4 for crow control in an industrial facility Location: DE-Worms (Industrial facility) Objective:Crow control Species causing damage:Large number of crows Area to protect:Pipelines, roofs, walkways, etc. Due to the waste heat from the industrial plant, the facilities are particularly frequented by crows in winter. At night the birds stay on the facilities and leave behind heavy contamination. After the device was put into operation, the birds completely withdrew from the site. Because of the strong bird pressure, the settings must be adjusted regularly. The BirdGard Super Pro PA4 was mounted on a tower in the middle of the site to cover the largest possible area. "In conclusion, it can be said that with the help of the BirdGard Super Pro PA4 the number of crows and thus the degree of contamination could be significantly reduced." (Norbert Jäger; Maintenance Planner / P&G Worms)

Bird Control with the Purivox Carousel -Triplex V

Customer Review of the Purivox Carousel - Triplex "V" for Bird control in a 38 ha Vineyard Location: Martinborough (New Zealand) Purpose: Bird control Harmful bird species: Starlings, blackbirds, thrushes, and waxeyes Protected area: 38 ha With 38 ha of productive vineyard, divided into 20 individual plots ranging from half to six hectares, the logistics of vineyard management at Murdoch James Estate require a lot of coordination. Late in summer, bird protection is a priority for Steve Plowman, who leads the four-person vineyard team. Steve says: "Our plots are on varied terrain – by the river, on slopes, on cliffs, and on flatter areas – and there are many trees that not only enhance the aesthetics of the estate and provide habitats for beneficial insects, but of course also serve as homes for many birds." "We cover all vines with bird nets, but as anyone in viticulture knows, it is extremely difficult to prevent especially the waxeyes from entering the nets. Even the smallest hole lets them in. Here we have large flocks of starlings, and also blackbirds and thrushes are abundant." "We found the gas cannons particularly good; they produce a strong, loud bang, and as with all gas devices, they need to be moved regularly. We used the mirror pyramid that sits on the tripod gas devices – this is very effective. When the gas device fires, the pyramid rotates, and the random flashing of the mirrors was very effective." Overall, Steve says he found the Purivox gas devices cost-effective. "They are reasonably priced and definitely perform their task very effectively."

Experience Report Purivox Carousel Triplex V

On the property of Kirchengut Demmin, 2 Purivox Carousel Triplex V units were installed for bird control. This was necessary to reduce feeding damage caused by the birds present. Location:Kirchengut Demmin Objective:Prevention of feeding damage Species causing damage:Cranes Area to protect:14 ha Since the installation of the devices, the arrival of cranes has significantly decreased.Feeding damage is now only sporadic. Without this deterrence, reseeding would have been pointless, as the cranes were still very active in the fields in recent days. Apparently, they repeatedly target the same spots in the field. Each device covered approximately 7 ha of field.To protect local residents, we had to limit the firing intensity and volume to a minimum.H. Kloke

Customer review of the Purivox Triplex "V" for bird control in a fruit orchard Location: El Salvador Purpose: bird control Species which are causing damage: variety of birds "I live in El Salvador, a tropical country with a large variety of birds that took the liking of my tropical orchard fruits. The Purivox gas cannon reduced the incidence of the birds. Our birds do not come in flocks, hence only a reduced incidence, but clearly a help. The unit has been operational for two and half years without problems. On a few occasions I needed technical assistance, the response via email has always been quick and helpful!" Karl H. May

Successful crow deterrence with the crow dummy

Crow control using crow decoys Location:Preetz Garden Objective:Crow deterrence Area protected:Bird feeding station Product used:Crow decoy Customer feedback:"The crow decoys arrived and I immediately put them into use: one was placed under our bird feeding station, and the other was hung in the apple tree beside it. By the next morning, the crows no longer approached the feeding station. Instead, they circled in the sky, cawing indignantly, and then left. They have not returned since. I must honestly say I did not expect such success and would like to thank you for this excellent product. At times, up to thirty crows were sitting at the feeding station, plundering the food and even attacking sparrows. Now, alongside sparrows and tits, woodpeckers, jays, and starlings are enjoying the station, and my food consumption has dropped by more than half."
