This review aims at giving all the information
and the key role of birds as bio-indicators of
environmentalhealth and help to detect pollution in the
environment such as water, air, soil, noise pollution, and
heavy metal contamination. Birds are useful to detect
forest recovery that properly helps forest management
and they have many useful roles to detect global
warming and climate change. Some birds help to detect
hotspot areas of biodiversity and a recent study even
says that birds can tell us about historic events of
pollution specifically air pollution. Therefore, many
problems according to environmental health and habitat
destruction can be measured in a very cost-effective and
easy manner with the help of birds as bio-indicators.
