In this undated photo provided by the California Department of Fish and Wildlife, a captured male red fox is seen. California wildlife biologists say they have caught two rare Sierra Nevada red foxes in three weeks. The red fox was listed as threatened in California in 1980. Scientists studying the animal had not been able to capture a red fox in a decade. The Sacramento Bee reports Thursday, March 8, 2018, that a nearly nine-pound female walked into a trap Tuesday near Manzanita Lake in Lassen Volcanic National Park. Scientists with the Department of Fish and Wildlife say they took blood samples and put tracking collars on the animals. (California Department of Fish and Wildlife via AP)
