"Once managed as commercial blueberry land, Kennebunk Plains WMA is jointly owned and managed by DIF&W and The Nature Conservancy. Of the 1,041 total acres of this WMA, about 600 are open grasslands. Sandplain grasslands are scarce in Maine. Consequently, bird species that prefer this kind of habitat are also uncommon or rare in the state. For instance, Kennebunk Plains Wildlife Management Area (WMA) hosts one of the few colonies of Grasshopper Sparrow found in Maine. Also present are Vesper Sparrow, Upland Sandpiper, Bobolink, Eastern Meadowlark, and Horned Lark. And while certainly not uncommon, you might encounter Wild Turkey, courtesy of a program of reintroduction, by the DIF&W.
Although an unmarked foot trail exists here, the best way to bird the plains is by road. Stop, get out, and scan the grasses for perching Grasshopper Sparrow. Look in the air for Upland Sandpiper and Horned Lark. And listen for birdsong of these and other species. Also spend some time watching and listening at either of the two DIF&W parking areas. Rachel Carson National Wildlife Refuge, in nearby Wells, has an interpretive trail with lots of birding opportunities."
