This is one of 3 large bull moose that we've seen around the Nature Center recently. Soon their antlers will stop growing, the velvet covering will be shed, and their temperament will be less friendly when the rut (mating season) begins. Rut-crazed bulls take no prisoners when it comes to charming a potential mate and discouraging any perceived competition, which can include other bulls, people, even cars and trains. Rivals are usually met with a chase and possible head-on collision from their massive antlers, so keep a heads-up approach when hiking and maybe see if your auto insurance has a rider policy for rutting moose!
