s. Although the Rail had coexisted with the cats for over 70 years, the introduction of rabbits enabled an increase in the cat population, leading to increased predation on rails in winter with the rabbits at seasonally low numbers.

It is distinguished from a stray cat, which is a pet cat that has been lost or abandoned, while feral cats are born in the wild; the offspring of a stray cat can be considered feral if born in the wild.In many parts of...

Habitat destruction
Habitat destruction is the process in which natural habitat is rendered functionally unable to support the species present. In this process, the organisms that previously used the site are displaced or destroyed, reducing biodiversity. Habitat destruction by human activity mainly for the purpose of...
