The purpose of Special Ornithological Researches (S.A.Rs) is to provide decision makers with accurate and up-to-date information on the potential impacts of a proposed project on bird populations and their habitats. This information can then be used to make informed decisions about whether to go ahead with the project and, if so, how to minimize its impact on birds and their habitats. By conducting these studies, decision makers can ensure that new developments are carried out in an environmentally responsible manner, helping to protect bird populations and their habitats for future generations.

S.A.Rs are usually conducted for projects that are likely to have significant impacts on bird populations, such as those involving large-scale infrastructure construction or residential or commercial property development in bird-rich areas.
