Which example would be classified as a local extinction?

The classification of local extinction pertains to instances where a species disappears from a specific area or region but continues to exist elsewhere. In this context, when a bird species becomes extinct in one city but remains present in other locations, it is an example of local extinction. This situation illustrates how a species is affected by local environmental, ecological, or anthropogenic factors, leading to its disappearance from a specific area while it continues to thrive in other habitats.

This contrasts with broader forms of extinction, such as global extinction, where a species ceases to exist entirely across all its habitats, or regional extinction, where it is lost from a larger geographical area. Understanding local extinction is vital as it can indicate ecosystem health and biodiversity, showcasing how species interact with their environment and the impact of human activity or changes in their habitat.
