The Volcano Rabbit

"The volcano rabbit, which is endemic to the Trans-Mexican Volcanic Belt surrounding Mexico City, is one of the world’s smallest and most unusual rabbits. It has small, round ears and, unlike other rabbits, makes high-pitched penetrating sounds. The rabbit lives on the slopes of the Iztaccíhuatl and Popocatépetl Volcanoes and in 16 small fragments of habitat on the slopes of the Pelado Volcano and the Tláloc Volcano in the mountain complex south of Mexico City. Frequent burning of the zacatón bunchgrasses, which the rabbit uses to construct and protect its burrows, as well as ever-increasing encroachment of settlements from the expansion of Mexico City, pose a threat to the survival of this charismatic species." http://www.biodiversityhotspots.org/xp/Hotspots/pine_oak/biodiversity.xml
