Birds play many roles, including predators, pollinators, scavengers, seed dispersers, pests, predators, nutrient cycling, ecosystem engineers, and many other services. However, the global decline in bird populations means that the ecosystem services provided by these birds are also declining [1]. The services birds provide are ecologically and economically important, but are not adequately appreciated due to insufficient information. Therefore, this review article aims to elucidate the role of birds in the agro-ecosystem and their benefits to humans in order to promote their conservation. Healthy bird populations and their habitats would help protect various ecological services that would ultimately improve human well-being.
