The document discusses three endangered species in Mexico: the American gray wolf, which exists only in captivity through a preservation program between the US and Mexico; the imperial woodpecker, which was last seen in Durango, Mexico in 1956 and its disappearance occurred between 1946-1965, leaving a difficult gap; and the Bengal tiger, whose numbers have declined drastically from 100,000 copies in the 20th century to an estimated 5,000 copies currently due to habitat loss, environmental changes, and division of populations.

1. ENDANGERED ANIMALS
IN MEXICO

2. AMERICAN GRAY
• American gray wolf, which currently exists only in captivity. As part of a
program to preserve created in 1980 between the United States and
Mexico, will be located 200 descendants of four founding individuals.

3. IMPERIAL WOODPECKER
In Mexico another bird, the beautiful imperial woodpecker left the scene less
dramatic, but, as all losses left a difficult gap to fill. It was the largest
woodpecker in the world, 51 to 56 cm long. The male sported a striking red
crest that ended in a point, while the females a black crest that curved
forward. His last record was in Durango in 1956. Although the date of
termination is not as precise; it is estimated that occurred between 1946 and
1965.

4. BENGAL TIGER:
From XX were said to have around 100,000 copies of Bengal tigers in the world.
Today is supposed no more than 5,000 copies, this disproportionately positive
ways speaking from mind.
The largest of the ancient ancestors of cats two million years ago the world, is
affected by its existence thanks to the exaggerated house of their species,
environmental changes and the division of the herd in different localities.
