![]() ![]() In this paper, we explore the possibility of employing MA aerosols as a bird deterrent strategy. Methyl anthranilate (MA) is a potent avian chemosensory irritant. Chemical repellents are typically used to render a resource unpalatable and, as a consequence, create a disincentive for a bird to visit a particular area. ![]() Birds can rapidly habituate to visual and auditory hazing if the use of these tactics falls into a predictable pattern, or if the sign stimuli are not coupled with a salient aversive reinforcing stimulus. Typical protective measures to keep birds away from areas include exclusion by use of netting, hazing (i.e., scaring tactics) and chemical repellents. The use of bird repellents may be required when human activities place birds in danger, e.g., hazardous waste sites, or when birds cause damage to crops, architectural structures, or are a source of zoonotic disease. In large warehouses or hangars it is therefore advisable to bring the fogger to the height where the birds are, so that the fog stays in the upper regions without disturbing any operation on the ground floor. Smaller droplets stay in the air much longer and disappear by evaporation and do not drop to the ground. Large droplets not only are relatively ineffective, they also tend to drop to the ground prematurely and are lost. Also, birds in flight with a breathing rate of 50-100 times higher than the resting rate show increased effectiveness. It has been shown that droplets below 10 microns are inhaled by birds much more and therefore show an increase in effectiveness. Smaller droplets in the 10-micron range are theoretically 27 times more effective than 30 micron droplets and five micron droplets even 216 times more effective for the same quantity of product applied. It is not always the quantity that determines fast reaction, but more the form for the specific application. The product alone does not guarantee the desired success. Despite its effectiveness, there are many factors that influence the effectiveness and desired results. invasive species), and that the value shift motivating discussion of novel ecosystems is necessary if we want to understand and protect nature in a changing world.įogging of Rejex-it ® TP-40 (Fog Force) offers a very efficient method for the management of nuisance birds in many diverse areas without any adverse effects to non-target animals. I defend a value-laden conception of novel ecosystems, showing that applied ecologists are comfortable with other value-laden concepts (e.g. But the critics are wrong that this is illicit. ![]() I show that proponents of the novel ecosystem concept have been unable to make it both value-free and precise enough to allow for applied use.Īlso, the critics are right to be suspicious, because a goal for many proponents of novel ecosystems is to bring new values into applied ecology. By labelling a human-modified system a ‘novel ecosystem,‘ they worry, we give policymakers a “license to trash nature.“ The critics are right to be suspicious. Critics have complained about its imprecision, and that it illicitly smuggles problematic ethical and political values into the science. May be applied with either thermal or mechanical foggers (Ultra Low Volume Foggers – ULVs).ġ - 6 applications (1-4 days apart) will usually sustain "conditioning" of birds.Īirborne mist, effective until it evaporates.The very idea of novel ecosystems has been controversial in ecology. Automated fogging systems inhibit any future re-infestation from new bird populations and assure a total bird free environment. Can be used with the discounted Falcon Thermal Fogger currently listed at our used farm equipment section.Īfter several exposures to the fog the birds generally leave the area completely and do not return for the season. ![]() It is formulated from the food grade ingredient, Methyl Anthranilate (MA), a naturally occurring compound with reduced risk to the environment.Īpplication method: thermal or mechanical fogger. Rejex-it® Fog Force™ Bird Repellent is a fogging agent that is an efficient tool for the management of nuisance birds without harming target and non-target birds or other animals. ![]()
