A handout picture dated 08 February 2015 and made available on 09 February by Oscar Montero, an inhabitant of Prioro town in Leon province, central Spain, shows a Cantabrian brown bear cub covered in snow at Montero's home exterior stairs. The Cantabrian brown bear is catalogued on the Spanish Red List of Endangered Species as “In Danger of Extinction”. The wild animal appeared in front of Montero's house after the town kept several days isolated by the snow and two and half days without electricity. As Montero explains, at first it was not clear to him what kind of animal it was, he thought it was a big dog, but then he realized that it was a bear cub, quietly climbing the stairs. “My first impulse was to go out and to touch it, but then I did not do it because I was warned that, being a baby, the mother could be close and it could be dangerous. When I was going to make a video with the phone and opened the door of the house, the animal turned and quickly slipped out behind the house”, Oscar says. (Photo by Oscar Montero/EPA)
