I made a trip through Quabbin Park starting before dawn and had a good number of Common Mergansers. The total for the morning made it to 377 with the largest group of 318 together. I also had a nice looking pair of Red Breasted Mergansers and a handful of Hooded Mergansers. Among the other waterfowl were 67 Ring Necked Ducks and a handful of Wood Ducks, Black Ducks, Bufflehead, Green Winged Teal, Mallards and Canada Geese.
At home I had a half dozen Tree Swallows and a few migrant Cooper's Hawks.
