Chemical Deterrents

An area of interest and considerable research is the use of chemical additives to make the toxic water unappealing to birds. Dyes are not effective as birds land on water of all colors seemingly without any prejudice. There have been several chemicals which have shown promise in reducing a birds intake of water. However none of these chemicals have been shown to be effective in defending a pond. It is unknown how the chemicals will hold up in a low pH. environment, as well as the effects of wind, UV radiation, temperature and time upon the chemical repellents. These chemicals are typically not manufactured in large amounts, so their cost is often high. Even if the chemical has a deterrent effect (and that has yet to be shown) the bird must land on the pond then ingest pond water to ingest the chemical deterrent. The act of landing on the pond and ingesting the water is often enough to cause mortality in birds.
