Abstract

Urbanization affected the birds; by establishing the urban areas, plantations had to be cut, which played an essential role in decreasing the diversity of birds. The bird’s species, including the migratory population, is a crucial bioindicator of the ecosystem that plays an important role in various natural phenomena, including the multiple variations in the various species of plants. The avian fauna is mainly affected by global change, roadways, noise pollution, urbanization, deforestation, risky human behaviors, climate change, and absurd land use. This study is based on a survey of peer-reviewed papers that summarize the effect of development, urbanization, urban areas, and climate change on the diversity of birds and migration according to their ecosystems. As a result, increasing population demands more urbanization and deforestation, but as a comparison, we need to establish effective strategies that can help avian fauna in urban areas and provide suitable conditions for the bird species.
