Lake Law and A.E.Sea are the most productive lakes for migrating waterfowl, loons, and grebes in early spring and late fall. All inland duck species have been found on these two lakes including Canvasback, Redhead, Greater Scaup, and all three merganser species. Northern Harriers can be found hunting the fields to the south and west of Lake Law. During migration Ospreys and Bald Eagles have been located near the small woods at the south end of A.E.Sea. In spring of 1992 a Cinnamon Teal was found on Lake Law and in 1989 an Eared Grebe was recorded on A.E.Sea.
Sparrows are present in good numbers in late fall.
Eleven species of sparrow have been seen at one time in this area . Most of the Fermilab records for Harris's Sparrow come from this hedgerow, including Fox, Vesper, and perhaps a Clay-colored later in the season. This area can also be productive for Orange-crowned and Pine warblers. Late spring and early fall are the best times to find migrating terns on these lakes. In 1993 a first year Common Tern was found on Lake Law.
