The Wikipedia article of the day for April 3, 2017 is Camas pocket gopher.
The camas pocket gopher (Thomomys bulbivorus) is a rodent native to the Willamette Valley of northwestern Oregon in the United States. The herbivorous mammal collects its food in large, fur-lined, external cheek pouches, then hoards any surplus in underground tunnels. The coat, dull brown to lead gray, changes color and texture over the year. The gophers' large, protuberant incisors are well adapted for use in tunnel construction, particularly in the hard clay soils of the Willamette Valley. They make chattering sounds with their teeth; males and females make purring (or crooning) sounds when they are together, and the young make twittering sounds. Born toothless, blind and hairless, the young grow rapidly before being weaned at about six weeks of age. The species is prey for raptors and carnivorous mammals, and host to several parasitic arthropods and worms. While population trends are generally stable, threats to the species' survival include urbanization, habitat conversion for agricultural use and active attempts at eradication with trapping and poisons. Fiercely defensive when cornered, the gopher may become tame in captivity.
