Fox takes over crow's nest CHARLOTTETOWN, Prince Edward Island, March 19 (UPI) -- Staff at the University of Prince Edward Island in Canada said a fox has taken up residence in a crow's nest on campus. University workers said the fox has been residing in the nest, located in a slanted tree behind the school's utility building, for about two weeks, the Canadian Broadcasting Corp. reported Monday. The workers said the home chosen by the fox, which is believed to have been living in the area for two years, has led to daily standoffs between the mammal and local crows. The fox isn't the first interloper, though. Squirrels were living there last fall, workers said.
