White-Throated Woodrat - Cover Requirements

Cover Requirements

White-throated woodrats must rely on self-constructed, ground-level shelter to lower the energetic costs of thermoregulation in extreme environments. White-throated woodrats typically use 2 types of shelter: houses, constructed at the base of plants, and dens in rock crevices. Other shelter types include holes and crevices in cutbanks along washes, subterranean burrows of other animals, piles of coarse woody debris, and human habitations and structures. Houses and dens are often maintained by successive generations of white-throated woodrats.

Houses are built by white-throated woodrats at the base of trees, shrubs, and cacti or in piles of coarse woody debris. White-throated woodrats prefer to construct houses at the bases of plants that provide both adequate shelter and food. Houses are constructed of various materials and are typically 3 to 10 feet (1–3 m) in diameter and up to 3 feet tall. Dens function as houses but are located in rock crevices, rock fissures, and under boulder piles.

Houses and dens enclose a system of runways and chambers, including the white-throated woodrat's nest. The nest averages 8 inches (20 cm) in diameter and is composed of soft, fine material including grass, shredded prickly-pear fibers, or juniper bark.

Famous quotes containing the word cover:

    If I use the media, even with tricks, to publicise a black youth being shot in the back in Teaneck, New Jersey ... then I should be praised for it, and it’s more of a comment on them than me that it would take tricks to make them cover the loss of life.
    Al, Rev. Sharpton (b. 1954)
