A study found that those species of birds that make cities home are highly adaptable and get used to human activity and the perils of urbanisation. [ Ссылка ]

Scientists reviewed 226 papers that were published between 1979 and 2020 and aggregated information on five major groups of bird traits from around the world that have been widely studied: ecological traits, life history, physiology, behaviour and genetic traits.

Urban avifauna is dominated by generalist species such as black kites and mynas while the specialists are on a decline, finds the study. Certain bird species in cities are smaller in size compared to their counterparts in non-urban areas, are stressed and are more aggressive in nature.

City planners need to rethink design, protect patches of native vegetation and water bodies to preserve the bird diversity in cities.
