The Guam rail is a flightless bird that is endemic to the Island of Guam, as its name suggests, which is located in the West Pacific.

To this day, it’s still the second bird in history to have recovered after being considered extinct in the wild. The reduction in the number of Guam rails took place after the Second World War. It was a consequence of the unintentional introduction of a type of tree snake that, by 1987, had already eradicated the Guam trail from its natural habitat. Now, after more than 35 years, its reintroduction to its natural habitat was made possible, keeping in mind that an active management of the species is still required to guarantee its protection.
