Synurbization refers to the effects of urbanization on the adaptation of wildlife, and how animals that live in urban environments versus nature environments differ. Urbanization, in terms of ecology, means developmental changes to the environment. These changes are often in benefit to humans. When applying synurbization to circumstances of urbanization where species have adapted, that adaptation does not occur by accident. Animals making adaptations to the environment change are often only doing so because of urban expansion into their current environments—e.g., the expansion of cities removing forested areas occupied species such as birds. Urbanization causes synurbization. Animals change behaviour as required for survival. Those species that better adapt and have favourable variations i
