With the last of the ice melted from lakes and reservoirs, waterfowl has been on the move north. I popped over to the Wallkill NWR the other day to see what was shakin’. Used to having the place to myself, with perhaps one or two other cars; I was stunned to find the parking lot full. I squeezed the car onto the grass and stomped off to the other side of Liberty Loop. The weeds, reeds and grasses that hide the ponds during the summer were thin and for the most part wind-blown. There were Song Sparrows on every high seed head tuning up their rusty voices. A shimmering mirage of Snow Geese circled the fields to land with a large flock of Canada Geese gorging on tender new shoots. The ponds themselves were loaded with Mallards, Pintails and Green-winged Teals. The resident Red-tailed Hawk sat on the wires and a female Northern Harrier coursed back and forth. The muskrats were swimming between lodges and turtles were sunning themselves. The marsh is feeling the change of seasons.
