CHECK UP: Game Wardens Terry Hughes, left, and Dave Simmons inspect a mixed bag of ducks Monday collected by hunters Paul Downs, bottom second from left, Jim Deaton, right, and Downs’ 10-year-old son, Camryn, on Lake Cobbossee in West Gardiner.  State and federal wardens were checking migratory bird hunters on the first morning of duck season in the southern zone of Maine, which is also the opening day of bird season across the state.   “We had a lot of misses,” Deaton said despite bagging several ducks.  “But it’s still a good day.”  The men were not issued any summonses.
