Hoffmeister 1944 Mustela frenata April 13 4 mi. NW San Bernardino, San Bernardino Co., Caly. Saw an adult long-tailed weasel slowly run across Highland Avenue (a main thoroughfare) just east of Mount Vernon Avenue in the above city at about 9 a.m., on a bright, sunny morning. It ran from a weedy grape vineyard across the road and stopped at the edge of a cultivated, bare field. It held its head high and looked about as I drove by in the car and remained this way until I could no longer see it. It appeared especially bold to me.
