Was headed north on Rte 3 in Bedford, just past where I-293 crosses, when I saw five flights of ducks at fairly low altitude cross Rte 3 on about a WSW heading. The flocks ranged from about 15 to 50 birds, fast wing beats but because I was in traffic I could not ID them.
There is, of course, the Merrimack nearby but also Nutt Pond a bit farther to the east and then Lake Massabesic on their flight course. This was around 1:30.
